I'm glad you're here, close to my heart.C

I'm shocked! An Alien! But, I'm more surprised that I'm not scared!

We're here now, in our backyard.

Oh I thought I saw a satellite.

Why did the Alien look for me???

An Alien! Right at our doorstep!;

I wonder which of the old spacecrafts on the Moon I'll see.

So many questions!!!

Earth looks so blue!3

It was as if I could...feel...the Alien's thoughts.

I'm so excited!

You'd have been smiling ear to ear throughout this journey.

I wonder if the Alien has a name.

It felt so peaceful, looking at the moon up close.

Ah it's so hard to see the stars with the Sun so close by.

I'm a bit nervous really.

We're leaving home behind.

We did say all the planets didn't we? We wouldn't miss out on Mercury and Venus.K

If we're lucky, we can find Gemlike Exogravic Matter near Planets or Stars.

If I stood on Mercury, I would only see one Sunrise every two years.&

I've never seen the Sun so big before!

One day in Mercury lasts over 1400 hours, just like Mondays for some people!A

Remember how you thought Mercury was actually made up of Mercury?

The Sun is HUGE!<

If I try hard, I can see Earth. Oh! I can also see the Moon!=

Venus is Earth's sister planet because of their similar size.

Where is that Alien from? Some hidden civilization on Mars?

It's too bad we won't be able to see Venus' surface.

The Drones sure are busy.

I close my eyes during Slipsream because it's so bright!/

I brought a Brontobyte worth of shows to watch.

I still find it odd that your favourite movie genre was Romance and not Sci-Fi.

When you glow it feels as if you're talking to me.

I wonder where the Alien came from.

I can't really see the Earth anymore.

Wasn't Venus really beautiful!

I'm still a little scared.

We actually found Exotic Matter near Venus! Too bad we can only analyse it back on Earth.

I'm thinking of a name for the Builder Drone.

Oh the sun is now smaller.

I wonder exactly what the Alien did to you?

I didn't see any signs of life on Mars.

Goodbye Earth, it was nice knowing you.

I guess the Alien isn't a Martian!

I'm still a little scared.

I gave the Builder Drone a name! Sculptor!

Oh the Sun is now much smaller.

I'm looking forward to seeing the Dawn spacecraft.

We're going to our first dwarf planet!

Wow the Dawn spacecraft was still orbiting Ceres!

If only you could see all this.

I'm getting used to the Alien zipping around constantly.D

You were right. You don't really see asteroids at the Asteroid Belt.$

The blue spots on Ceres were pretty!3

I wonder how much the Great Red Spot has shrunk by?

Cryonap makes me feel groggy for a while.

I still think the name 'Starsoul' is a little simplistic. But that's what you would have wanted.

The Aurorae on Jupiter is mesmerising!

The Great Red Spot really shrunk huh!

I can't wait to see the Rings!

The Alien just helps me, but doesn't communicate with me.

Saturn has Sixty Two moons!!! Sixty Two!B

Saturn's biggest Moon Titan, has more water on it than Earth does!

It's strange, but I don't feel like I miss Earth. It's our home after all...Why is that?1

I'm still trying to get used to the Super Boosts.

What form of propulsion does that Alien ship use???

It's such a coincidence that the Alien has a Humanoid Bipedal form like us!

Sensors indicated that Saturn had 63 moons! A new one appeared!

Ahh, I do miss the sound of your laughter.

I'm more curious about the Rings of Uranus than those of Saturn.\

If only I could listen to one more of your space jokes, even though I'd just groan as usual.J

We wouldn't have come this far without the discovery of Solid Dark Matter.

Maybe, I'm just not homesick yet?

The constellations still look the same from here.

Uranus' would have been 'Caelus' if we'd used the Roman name like the other planets.

I bet we'll see something similar to the Great Dark Spot.

Neptune's Rings are named after Courage, Liberty, Equality and Fraternity.

You used to like it that Neptune is blue. 'It feels right' you said.<

I thought I saw the Alien smile when it stopped by just now.]

Well, this is the last of the eight planets. But we're not even halfway through our backyard.

It's not me is it? You seem to be glowing brighter the busier I get.I

What was it you asked me? "What songs do planets sing? Neptunes!" *Groan*

The sun is so much smaller but I still can't look at it directly.

We're only going to Pluto, and not Eris, Charon or the other Dwarf Planets.

I'm kinda glad Charon is now considered a Dwarf Planet. Hooray Binary Systems!

The Kuiper Belt is just like the Asteroid Belt, nothing here to see all around.

I think turning yourself into a diamond is the 6th best idea you've ever had.

It's hard to tell, but you glow a bit brighter with every beat of my heart.

Doesn't the Alien have to be anywhere else?

Pluto is a really really cold place. Liquid Nitrogen would become rock solid there.

If you look from a certain angle, Pluto and Neptune share the same orbit around the Sun!

I think Pluto's Sputnik Planitia is simply beautiful.

Some people think that Sedna is part of the Inner Oort.

Should I just refer to the Alien as ELF? Enigmatic Life Form?

This is the last Celestial Body we'll visit in our backyard!"

Let's see how red Sedna really is!

I rarely go out of the shuttle. Sculptor does all the repairs for me.

I wonder if there are simple lifeforms within our Solar System.

It's going to be a lot of emptiness from here on!

I don't regret leaving Earth at all.;

Sedna looked really lonely. I don't know how to explain it.

Actually, come to think of it, compared to ELF, we ARE the simple lifeforms!R

Can you imagine if the known galaxies are actually orbiting something even larger.

If we are lucky we will see comet type objects!

You said that Space Manta Rays would be cool. I thought Space Turtles would be cooler.

I have our Map of the constellations ready.

You know, I figure why I don't miss Earth so much. It's because you're here with me.1

Are we going to see even more lifeforms like ELF?

I saw that from far off! A comet!

They say this is the area where comets like Halley's comet come from.

They say that eventually, the Inner Oort will thin out as the comets move out to Outer oort.)

What would Alien civilizations look like?

How many variations of the 'Full Tour of the Constellations' did we come up with?

Watching all those Sci-Fi movies prepared me for this not a single bit!

This is it, the end of our backyard! This is where our journey really begins!

Home is where the heart is. I understand that now.

"What time do Astronauts eat? At launch time!"

My heart, it is singing. Can you feel it?

After this, the 88 Constellations! I can't believe it!

I wish we could go faster!

I'd Cryosleep all the way if I didn't want to see everything first hand!%

Our first stop after this, Centaurus!

Centaurus was one of the old 48 Constellations.

Constellation' can mean a group of stars or a region of the sky.p

You had a habit of calling a pattern of stars a 'Constellation', I had to keep telling you that's an 'Asterism'.D

The Alien stared at me for a moment just now, and then whizzed away.

Goodbye Solar System!

The nearest star to us is actually Proxima Centauri.C

We are visiting the Brightest star from Centauri, Alpha Centauri A.

Centaurus is named after the mythological half human half horse, the Centaur.

A 'Spectral Class' of a star goes by Letters, from hottest to coolest, O, B, A, F, G, K, M. I remember it easily by thinking 'Oh boy a Friendly Green Kind Martian!'

We are visiting the Brightest star from Centauri, Alpha Centauri A. It is a G2 V type star, meaning it is a yellow , main sequence star.<

Centaurus is not the only Constellation depicting a Centaur!8

Would the Alien have come to us if you were still alive?F

I think I want to write a song. Remember our favourite Constellations?

Alpha Centauri is a Triple Star system made up of stars Alpha Centauri A, B and C.

Alpha Centauri A has slightly more mass than our Sun. It is 1.5 times brighter!

Centaurus is part of the 'Hercules' Constellation Family.

I got goosebumps looking at Alpha Centauri A! Well, not straight at it of course.

Spectral Class O type stars are blue, and are the hottest types, with temperatures going above 30,000 K.#

Crux is the smallest Constellation!

Crux has an Asterism commonly known as the Southern Cross.

The Southern Cross is well known in popular culture.4

Crux is part of the 'Hercules' Constellation Family.E

'Acrux' is actually one of the stars in the Alpha Crucis star system.

'Acrux' is otherwise designated as 'Alpha Crucis Aa'.

One day, the stars in Alpha Crucis will go Supernova!

I wonder how far away ELF is from home?

How should the song start, hmmmm...

Wow, to be at the Southern Cross! I bet plenty of sailors were looking in our direction![

Spectral Class B type stars are blue white, with temperatures between 10,000 K to 30,000 K.

In Spectral Classes of stars, Also, 0 to 9 is used to subdivide each class within its range, so for Class B, B0 is the hottest and B9 is the coolest.

Musca is the first of the 'Bayer' constellation family we are going to.

Musca means 'Fly' in Latin.

Of the many stars in Musca, we are going to Alpha Muscae. It has five times the Sun's radius!

Alpha Muscae is turning into a Subgiant star.

Why would they name it after a fly though? Why not a Bee?

Oh! If I could 'feel' ELF's thoughts, then could ELF 'feel' mine?

Having no sunrise and no sunset in this shuttle makes me not know when to sleep.

Chamaeleon is of the 'Bayer' family of constellations.

Chamaeleon's brightest star, Alpha Chemaeleontis, is also its nearest star to Earth.Q

Alpha Chamaeleontis is bright enough to be seen with the naked eye back on Earth!

"Why did the Sun go to school? To get brighter!"V

I think there are more types of Aliens out there. ELF didn't seem surprised to see me.

Spectral Class A type stars are white, with temperatures between 7,500 K to 10,000 K.

Stars have luminosity classes, from hypergiants to dwarves they are 0, la, lab, lb, II, III, IV, V.

Chamaeleon is named after the chameleon, a kind of lizard.

The Apus asterism represents a Bird-Of-Paradise

Spectral Class F type stars are yellow white, with temperatures between 6,000 K to 7,500 K.

Under supergiant luminosity classes we have, '0' for hypergiants, 'la' for luminous supergiants, 'lab' for intermediate luminous supergiants and 'lb' for less luminous supergiants.O

Apus means "Without Feet" in Greek! They thought Birds-Of-Paradise had no feet!

Apus belongs to the 'Bayer' family of constellations.

The brightest star in Apus is 'Alpha Apodis'. It is 980 times our Sun's luminosity!

Alpha Apodis is Giant Star with a radius 48 that of our Sun's!

How old do you think ELF is?4

From Earth, the Milky Way covers most of Apus' area._

Any part of a constellation that is covered by the Milky Way is called the 'Zone of Avoidance'.

Dust and gas in the Milky Way makes it hard to observe stars and galaxies in the 'Zone of Avoidance'.

Triangulum Australe' means 'Southern Triangle'.

Triangulum Australe is different from Triangulum, which we'll be getting to much later!

Luminosity class 'II' stands for bright giants, 'III' for normal giants, 'IV' for subgiants and 'V' for Main Sequence...like our Sun!

Spectral Class G type stars are yellow, with temperatures between 5,200 K to 6,000 K. Our Sun is a G2V itself.

Triangulum Australe is part of the 'Hercules' family of constellations.

You can't see Triangulum Australe from the Northern Hemisphere of Earth.T

We are going to Alpha Trianguli Australis, the brightest star in this constellation.:

The star Alpha Trianguli Australis is also known as Atria.

Alpha Trianguli Australis is an orange Giant Star.

What do animals on ELF's homeworld look like?

Circinus' means 'Compass', the kind that you use for drawing circles.

The Milky Way also runs through Circinus, so you see lots of stars here.W

Spectral Class K type stars are orange, with temperatures between 10,000 K to 30,000 K.

Circinus is of the 'La Caille' Family of constellations.J

The 'La Caille' family of constellations represent scientific instruments!

We are going toward the star 'Alpha Circini'.

Alpha Circini has less than twice our Sun's mass, and double its Radius.=

Alpha Circini is really hot, at 7500 Kelvins, so it is white!

Alpha Circini could be 12 Million years old.

I wonder what ELF eats.

Observed from Earth, the mysterious 'Great Attractor' is somewhere around this and the Norma constellation.

The 'Great Attractor' is beyond 200 Million light years away from our Solar System.

The 'Great Attractor' seems to be attracting entire Galaxies toward it!

Lupus' means 'Wolf'. This asterism used to be part of the Centaurus constellation.

Lupus belongs to the 'Hercules' family of constellations.

Spectral Class K type stars are red, with temperatures between 2,400 K to 3,700 K.

Why did the Moon skip lunch? Because it was full!

We are on direct course to Lupus' brightest star, Alpha Lupi.

Alpha Lupus is one of the nearest Supernova candidates to Earth.A

A Supernova near enough to our Solar System could harm the Earth.

Does ELF have the same senses as us Humans do?

I was awestruck when you told me that the 'Great Attractor' was being pulled by a 'Shapley Supercluster'.

Norma' means 'Normal'. It's really referring to a Right Angle.

Norma's asterism is a Carpenter's Square.

Norma belongs to the 'La Caille' family of constellations.

You were often reminded of a certain actress when you saw the Norma constellation.

The Gamma Normid meteor showers originate from Norma.

The Normal Cluster is a cluster of Galaxies 222 Million Light years away.

The Norma Cluster is estimated to be 10 to the power of 15 times the mass of our Sun!

The Earth is barely an atom in a sea of stars. And that is an understatement.

I miss your voice dearly.

What is the extent of ELF's powers?

Ara' means 'The Altar'. The name has its roots in Greek mythology.

Ara belongs to the 'Hercules' family of constellations.

The Red Hypergiant star 'Westerlund 1-26' is in Ara.b

Westerlund 1-26' has 1500 times the radius of the Sun! It is one of the largest stars known to us.

We are going to the star Beta Arae. It is about 5600 times as luminous as our Sun!

How fast can ELF go? ELF's ship flies circles around us and it doesn't look like it is affected by momentum.M

I'm out of jokes, I was never as good at you with coming up with space jokes.

Corona Australis belongs to the 'Hercules' family of constellations.'

Corona Australis mans 'Southern Crown'.

Corona Australis is the counterpart to Corona Borealis.

We are going to the star Alpha Coronae Australis. It is also called Alphekka Meridiana.

The meteor shower that comes from this constellation are known as the Corona Australids.9

Did ELF's civilization ever go through a phase like ours?

You gave the nickname 'Crown Under' to Corona Australis. I don't think it ever caught on.

There is a snail with the name Telescopium Telescopium!

Telescopium is represented by a ...you guessed it...Telescope!

The Telescopium constellation is of the 'La Caille' family of constellations.

We are going to Alpha Telescopii. It has about 3 times the radius of the sun!

I wonder what kind of constellations ELF had back at its home planet?

The 5th best idea you've had was to plan that visit to that Observatory in Hawaii for my birthday.

The Indus constellation is represented by the Indian.

Indus belongs to the 'Bayer' family of constellations.

There doesn't seem to be any meteor showers originating from Indus.

The star we are going to is Alpha Indi, also known as 'The Persian'.U

Alpha Indi is estimated to be a Gigayear old! Or a short scale Billion if you prefer.

Does ELF even have a home planet? Maybe ELF's people have already colonised an entire galaxy!

At times, I feel bad not going back to share our experiences with everyone else.

The Pavo constellation is represented by a Peacock.

Pavo is the radiant of the Delta Pavonids and August Pavonids meteor showers.

Pavo is from the 'Bayer' family of constellations.

We are going toward Alpha Pavonis, it is actually a binary star![

Alpha Pavonis is also named 'Peacock'. So the Peacock star is in the Peacock constellation!

Alpha Pavonis is a spectroscopic binary star, but once we get near enough...!

How long lived is ELF? It's spending so much time on us, yet maybe, to it, it is just a negligible amount of time?

Octans is named after the Octant, a navigational instrument.;

Octans belongs to the 'La Caille' family of constellations.

Octans brightest star is Nu Octantis, it is a spectroscopic binary star.W

It is suspected that there is an exoplanet at Nu Octantis. Let's keep a lookout for it.

Nu Octantis is estimated to be 2 to 3 Gigayears old!a

I would like to ask ELF if to them, there is such as thing as 'Time' the way we humans define it.

Hydrus is represented by a Male Water Snake. Not to be confused with the constellation Hydra!

Hydrus is of the 'Bayer' family of constellations.

We will be going to Beta Hydri, it is both Hydrus' nearest and brightest star!

Beta Hydri is what our sun might look like in its next stages of evolution.

The Beta Hydri system has appeared in quite a few works of fiction, ashamedly none of which I have read.C

Maybe ELF has the power to go into a blackhole and survive! Nahhhh.

Tucana is named after the bird 'Toucan'.2

Tucana is of the 'Bayer' family of constellations.

Tucana has some interesting Deep-sky objects!

You can see the Tucana Dwarf Galaxy, it is 2.8 Million Light Year away from our Sun. (Wow)

The Small Magellanic Cloud is a dwarf galaxy you can see at Tucana.

When we get to Alpha Tucanae, we can finally see for sure if it is a binary star!

Maybe, ELF doesn't even talk! Maybe ELF just 'thinks' to other ELFs!z

The 4th best idea you've ever had was to take drawing lessons so that you could draw beautiful maps of the constellations.

The Grus constellation is named after the 'Crane', a type of bird.

Grus belongs to the 'Bayer' family of constellations.

The Spare-Tyre Nebula is a deep-sky object in Grus. What a funny name!

We are heading to Grus' brightest star, Alpha Gruis. It's also known as Alnair.

Alpha Gruis has 3.4 times the radius of our Sun.+

Alpha Gruis is about 100 million years old!

Going to the constellations may be meaningless to ELF, because our constellations don't make sense to it.

The Phoenix constellation is named after the mythical Phoenix!

Phoenix, Grus, Pavo and Tucana are together known as the 'Southern Birds'.

Phoenix is of the 'Bayer' family of constellations.

Interestingly, Alpha Phoenicis is an orange giant. I like to imagine it is a giant phoenix egg!

The brightest star in Phoenix is called Alpha Phoenicis, and is also known as Ankaa.h

Phoenix is the radiant of two meteor showers! Known as the Phoenicids, they appear in July and December.X

The Phoenix Cluster, seen in the Phoenix constellation, is 7.3 million light years wide!R

The El Gordo, seen in the Phoenix constellation, has a mass of 3 quadrillion suns!

I wonder if ELF came from a higher or lower gravity planet?

Oh look! It's the planet Vulc...just kidding!

Eridanus is the sixth largest constellation.#

Eridanus is represented by a river.

Eridanus is the first of the 'Heavenly Waters' family of constellations we are going to.H

The brightest star in Eridanus is Alpha Eridani, also known as Achernar.d

Alpha Eridani is spinning so fast that it is an 'Oblate Spheroid'. It looks like a flattened sphere!S

Nu Eridanis and Omicron Eridanis are both meteor showers originating from Eridanus.

There is a mysterious Supervoid in Eridanus, one billion light years wide. It is empty, no galaxies, nothing!

Can ELF's spaceship travel faster than light? Ooo, does ELFs know if anything travels faster than light?

The Fornax constellation is named after the furnace.6

Fornax is of the 'La Caille' family of constellations.

I wonder if we'll ever visit the Fornax Galaxy. Of course it's 500,000 light years away...

We are heading toward Alpha Fornacis. It is a binary star 2.9 billion years old.Y

What is ELF's civilisation like? Would humans ever understand their customs or lifestyle?

The name Cetus refers to a sea monster, but is also known as a whale.

Cetus is part of the 'Perseus' family of constellations. Perseus killed Cetus!

Cetus is not part of the Zodiac, but sometimes the moon and the planets may be in it for a short time!

We are going toward the star Beta Ceti, also known as Diphda, meaning 'Frog'.

The furthest group of Galaxies we know of is JKCS 041, seen in Cetus,is 9.9 Billion light years away.

The one Messier Object here is M77, a spiral galaxy.

A Spiral Galaxy is a flat rotating disk made up of stars, gas and dust. In the middle of it is a concentration of stars we call the bulge.

Does ELF watch television or play games? Do they even have movies or games in the first place?

The third best idea you've ever had was to push for the inclusion of the feelings chips in the drones.

Sculptor! Our Builder Drone's namesake! It is represented by a 'Sculptor's Studio'.

Sculptor is from the 'La Caille' family of constellations.

We are going toward Alpha Sculptoris. It has five times our Sun's mass!

The Cartwheel Galaxy in Sculptoris is actually made up of a merger of two galaxies!

How far can ELF feel someone's thoughts? Can another ELF block out their own feelings if they want to?

Hey Sculptor look we're going toward *your* constellation cool huh!

Piscis Austrinus means 'Southern Fish'.

In Greek mythology, Piscis Austrinus is the parent of the two fishes in the Pisces constellation.

Piscis Austrinus is of the 'Heavenly Waters' family of constellations.

The brightest star in Piscis Austrinus is Fomalhaut, or Alpha Piscis Austrini.

Fomalhaut means 'Mouth of the whale.'

Fomalhaut is one of the more well known stars to have a planetary system.

Maybe ELF has gone to Earth before! Am I the first human to see ELF?

Microscopium is a constellation represented by the microscope.

Microscopium is of the 'La Caille' family of constellations.j

Our destination this time is to Gamma Microscopii. It seems to be a member of the Ursa Major Moving Group.

The Ursa Major Moving Group is a set of stars that seem to be roughly moving in the same direction and speed.

The Microscopids are a meteor shower that radiate from Microscopium.L

There is Microscopium Void and a Microscopium Supercluster. What a contrast!<

I wonder what the temperature and air is like in ELF's ship.

Sagittarius is represented by a Centaur, just like Centaurus! It is shown holding a bow and arrow.

In Greek mythology, Sagittarius' arrow is pointing at Antares, the heart of Scorpius.

Sagittarius is the first of the 'Zodiac' family of constellations we are visiting!

The Zodiac is the area of the sky where the sun 'travels' through the year.

12 of our Drones are named after the Zodiac! Well sort, of, it's more like their Astrological names.8

The brightest star in Sagittarius is Epsilon Sagittarii.e

Epsilon Sagittarii is a binary star system, with one of the stars glowing a beautiful Blue and White.

Sagittarius has fifteen Messier Objects! M18, 21, 23, 25 are open clusters, M22, 28, 54, 55, 69, 70, 75 are globular clusters, M24 is a Milky way star cloud, and M8, 17 and 20 are Nebulas with clusters.

Globular Clusters are a collection of stars that orbit their galactic core, they're called 'Globular' because they are bound together by gravity in shape of a sphere.

Open Clusters are a group of stars, up to a few thousand at a time, that are loosely bound by gravity and sort of, orbit their galactic centre together.b

What if...theres many ELFs and it's just that they all look the same so I think it's just one ELF?

Capricornus is represented by a half goat, half fish creature.

Capricornus is the second of the 'Zodiac' family of constellations we are heading to!

There is a galaxy group in Capricornus that is predicted to turn into a giant galaxy millions of years from now.R

We are going toward Delta Capricorni, an interesting eclipsing binary star system!

If you watch an eclipsing binary star system from Earth, their orbits will make them take turns eclipsing one another.

The Messier Object in Capricornus is M30, a globular cluster.

Does ELF see into the visible spectrum like we do? Can it see Ultraviolet or Infra-red, or...even to higher or lower wavelengths?

The second best idea you've ever had was...dark chocolate with strawberry spread on toast!

Aquarius is represented by the 'Water Bearer'.

Aquarius belongs to the 'Zodiac' family of constellations.

An Ultracool dwarf star TRAPPIST-1 in Aquarius, may have seven earth like rocky planets!i

There are a few meteor showers with radiants in aquarius, with the strongest one being the Eta Aquariids.

The Eta Aquariids meteor shower originates from Halley's comet! This comet can be seen from earth every 75 or so years.

We will be going toward Beta Aquarii, or Sadalsuud. It's actually a double, well, triple star, but not a binary system!

A Double Star are stars in the same line of sight from Earth, but necessarily not be near or orbiting each other.

A Double Star and a Binary star are not the same!

Three Messier Objects are in Aquarius, they are M2 and M72, both Globular Clusters, and M73, an Asterism.

If space is infinite, then how far has ELF tried to go? Maybe the universe really wraps around into itself!

Equuleus means 'Little Horse', like a Foal. It's the second smallest constellation!

Equuleus belongs to the 'Heavenly Waters' family of constellations.

The brightest star in Equuleus is Alpha Equulei. It is also named Kitalpha, meaning 'A Piece of the horse'.

Alpha Equulei is a Spectroscopic Binary. The stars revolve around each other every 98.8 days.

Because of Equuleus' small size, there aren't any meteor showers associated with it.

This is our first foray into the 'Northern hemisphere' of constellations! It doesn't really mean anything except to humans though.

Are there weapons on ELF's ship? It looks harmless enough...

The Pegasus constellation is named after the Winged Horse, Pegasus.

Pegasus is of the 'Perseus' family of constellations.

The Eta Pegasids are a meteor shower that happens in May.

Stephen's Quintet is a cluster of five galaxies in Pegasus. One day, they'll merge into one large galaxy!

The brightest star in Pegasus is Epsilon Pegasi. It is a supergiant that has 185 times the radius of our Sun!

M15 is a Messier Object in Pegasus, it is a globular cluster.

Wow, what would animals from ELFs planet look like? Would they have blue dogs?

Lacerta is a constellation represented by the Lizard.

Lacerta belongs to the 'Perseus' family of constellations.

BL Lacertae is a galaxy with an Active Galactic Nucleus. BL Lacertae Objects are named after it.}

BL Lacertae Objects are different from quasars in that are active, but mostly in the lower part of the electromagnetic range.

The brightest star in Lacerta is Alpha Lacertae, it is 400 Megayears old!

What is ELF scared of, does ELF have any phobias?

Cepheus is named after a King in Greek mythology.

Cepheus' wife, Cassiopeia, and daughter, Andromeda, also have Constellations named after them.

Cepheus is of the 'Perseus' family of constellations.

The most massive black hole known to man, 'S5 0014+81', is 10,000 times bigger than the black hole in our Milky Way._

The brightest star in Cephei is Alpha Cephei, or Alderamin. It spins at a really fast 246 km/s!

The Milky Way is in a Void, does this mean ELF traveled in from outside the void? Or is ELF's home also within our void?$

Your best idea ever... was to exist.

Cygnus is a constellation named after the Swan.

The Northern Cross is an asterism in Cygnus, a Northern Counterpart to the Southern Cross.

Cygnus is from the 'Hercules' family of constellations.

Cygnus A' is a Radio Galaxy, meaning that it is luminous at radio wavelengths! Not that I can see radiowaves...

We're going to Alpha Cygni, better known as Deneb. It is part of both the Northern Cross and Summer Triangle Asterism.

The Summer Triangle is an Asterism spread out across a wide area. It is made up of Deneb, Vega and Altair.

Deneb is very luminous, almost 200,000 times that of our Sun.

Deneb has 200 times the Sun's diameter! If we replaced our Sun with Deneb, Earth would be inside it!F

Cygnus has two Messier Objects, it is M29 and M39, both open clusters.

Has ELF seen creatures that naturally live in space instead of on planets?

Lyra is a constellation represented by the Lyre.3

Lyra is of the 'Hercules' family of constellations.

Lyra's brightest star, Vega, is part of the Summer Triangle as well.|

Epsilon Lyrae is known as the 'Double Double', because it is two sets of Binary Stars orbiting each other! How cool is that?

Beta Lyrae Variables are Binary stars where one of the stars is already a giant, and is periodically losing mass to its smaller partner.X

We are going toward Alpha Lyrae! Many people know it as 'M.Bis...', sorry I mean 'Vega'.

Vega was an important star in the history of astronomers. Among other things, Vega was the first star other than our Sun to be photographed and one of the first to have its distance measured.

The April Lyrids originate from Lyra, and occur from mid April onward.

The two Messier Objects in Lyra are M56, a globular cluster, and M57, a planetary nebula.

Does ELF listen to music? Maybe there's no such thing as music in ELF's culture.

'Vulpecula' means 'Little Fox'. It used to be 'Vulpecula et Anser', for 'Little fox and goose', but now Anser is the name of its brightest star instead.:

Vulpecula is from the 'Hercules' family of constellations.

The brightest star in Vulpecula is Alpha Vulpeculae, it is also known as Anser. It is also part of the Arcturus Stream, a type of Stellar Stream.

Stellar Streams are a group of stars that were once a globular cluster or dwarf galaxy, but torn apart and stretched out along its orbit.

The Messier Object in Vulpecula is M27, a planetary nebula also known as the Dumbbell Nebula.

ELF zipped by just as I was thinking if it minded that I referred to it as 'ELF', and it gave me a thumbs up! Does ELF read minds??? Does thumbs up mean the same to ELF as to humans?

Sagitta means 'Arrow'. It is a small constellation, third smallest, in fact!6

Sagitta is of the 'Hercules' family of constellations.

Gamma Sagittae is the brightest star in Sagitta. It is a Red Giant.

Sagitta has one Messier Object, M71. It is a globular cluster.

When ELF zipped by just now I thought hard 'Give me a thumbs up!' but nothing happened.

Delphinus is a constellation named after the Dolphin.

Delphinus is of the 'Heavenly Waters' family of constellations.

Beta Delphini is the brightest star in Delphinus. It is a binary star where both stars orbit each other every 26.6 years.

Beta Delphini is also known as Rotanev, which is 'Venator', Latin for 'Hunter', backward, which in Italian is 'Cacciatore', for Niccolo Cacciatore, the man who named it after himself!

Alpha Delphini is also known as Sualocin, which is 'Nicolaus' backward, which in Italian is 'Niccolo', for Niccolo Cacciatore, the man who named it after himself!

This time when ELF zipped by I visualised a picture of ELF giving me a thumbs up. And ELF gave me one! ELF can read my mind!!!

Aquila means 'Eagle' and is also represented by one.5

Aquila is of the 'Hercules' family of constellations.

The brightest star in Aquila is Alpha Aquilae, also known as Altair. It is one of the Stars that make up the Summer Triangle.

Altair rotates so fast at 286 km/s at its equator that it is oblate, with the diameter at the equator 20% greater than the diameter at its poles.

NGC 6751 is a nebula in Aquila also known as the Glowing Eye because... it looks like a glowing eye! It's not the only one though.

Are there avians in ELFs world then? There must be worlds where nothing grew to have wings and to fly in the sky.

Scutum is a constellation represented by a Shield.

Scutum belongs to the 'Hercules' family of constellations.

Our target this time is Alpha Scuti! It is an orange K-type Giant K-type stars are cooler than our sun, which is a G-Type star.

Scutum has two Messier Objects, M11 an open cluster also called the Wild Duck Cluster, and M26, another open cluster.

Did ELF's world also have a shield around it that protected it from their Sun? Or maybe it didn't need one. Or...maybe it was a rogue planet and didn't have a sun!

The constellation Scorpius is represented by a Scorpion.5

Scorpius is of the 'Zodiac' family of constellations.

This time, we are going to Alpha Scorpii, it is also known as Antares, meaning 'Anti-Ares', in this case meaning Mars, due to it also having a reddish hue.

Antares is a supergiant that has over 800 times the radius of our sun! It might go supernova within the next million years but I don't think I'll get to see that.

The Alpha, Chi and Omega Scorpiids are meteor showers that radiate from Scorpius.

Scorpius' four Messier objects are, M4 and M80, both globular clusters, and M6 and M7, both open clusters.

Does ELF feel pain? For all we know, ELF doesn't feel anything like we do!

The Libra constellation is represented by weighting scales. It also used to be called the Scorpion's claws, in this case, Scorpius.

Libra is of the 'Zodiac' family of constellations.

Gliese 581 is a planetary system in Libra thought to have planets that may support life! Could the Alien be from there?

We are visiting Beta Librae, or Zubeneschamali. It means 'The Northern Claw', of Scorpius.

What is ELF's moral code like? What kind of values does it have?

The Ophiuchus constellation is represented by a man grasping a serpent. That serpent is the serpent in Serpens! Now say that 5 times quickly.

Ophiuchus is of the 'Hercules' family of constellations.

We are going to Alpha Ophiuchi, also known as Rasalhague. It is a binary system where the main star is spinning at about 88% of the rate which would cause it to break up!

Ophiuchus has seven Messier Objects and they are all globular clusters! They are M9, M10, M12, M14, M19, M62 and M107.

I wonder if ELF has ever seen major conflict. Or has it always lived a peaceful life?

Serpens is a constellation represented by the snake. It is unique in that this constellation is split into two parts, with Ophiuchus in between them!

The two parts of the Serpens constellation are known as Serpens Caput and Serpens Cauda.6

Serpens is of the 'Hercules' family of constellations.

This time we are going to Alpha Serpentis. It also has another name 'Unukalhai', which means 'The serpent's neck'. It is a Giant orange star that has 70 times our sun's luminosity.

Hoag's Object is a ring galaxy found in Serpens. It has a core of older yellow stars, and a beautiful ring around it made up of young blue stars. We will go there one day!

There is a Death Star galaxy, part of 3C 321, a system of two galaxies that are rotating around each other. The Death Star Galaxy is shooting a jet of matter toward the smaller one, thus its name.v

The two Messier Objects in Serpens are M5, a globular cluster, and M16, a H II region, also known as the Eagle Nebula.

Even if ELF doesn't speak, it must have a written language right? Do they have books?

Corona Borealis means 'Northern Crown'. It is named is derived from the shape of it's brightest stars, which form a semi-circular arc.

Corona Borealis is the first of the 'Ursa Major' family of constellations we are going toward.

The brightest star in this area is Alpha Corona Borealis, also known as Alphecca. It is a binary star with one white star and one yellow star.

I wonder what ELF's world leader is in charge of? Do they have a world leader?

Hercules is a constellation named after Hercules, a Greek mythological hero. It is the fifth largest constellation!

Hercules belongs to the 'Hercules' family of constellations...of course.]

The brightest star in Hercules is Beta Herculis, a binary star. It is also named Kornephoros.

The Hercules Cluster, or Abell 2151, is a cluster of about 200 galaxies. This is different from Hercules Globular Cluster, or M13, which is a cluster of about 300,000 stars.

Hercules has two Messier Objects, M13 and M92, both globular clusters.

Is ELF considered a kid? An Adult? Humans grow from babies to adult size, for all we know, ELF could grow to 10 meters tall!

The Draco constellation is named after the Dragon. If you are at the north pole, the stars here would never set because Draco is circumpolar, so you can see them all the time, well, except when the sun is out.

Draco is of the 'Ursa Major' family of constellations.

If you are at the southern hemisphere of earth, you would not see the Draco constellation at all.

The brightest star in Draco is Gamma Draconis, or Eltanin, meaning 'The great serpent'. It is an orange hued K-type star.

There is one Messier Object in Draco, M102, it is known as the Spindle Galaxy.

If ELF watched Earth's science fiction films would it find them absurd?

Ursa Minor means 'Lesser Bear', but some people also call it the Little Dipper.

Ursa Minor is from the 'Ursa Major' family of constellations.

Polaris! Also known as the North Star! Remember when we found out it was actually made up of three stars? You Were Shocked!

If you were near Polaris and you could see Earth, you'd be looking at the North Pole!

When we reach Polaris, we're going to celebrate with a bunch of yummy food! We'll call it 'Feast of the North Star'![

The Ursids are a meteor shower that occurs in Ursa Minor, around between December 18 to 25.

Can ELF also feel the emotions of animals? Like sheep or rabbits?

Camelopardalis is named after the Giraffe! That's because originally, in greek it is the combination of 'Camel' and 'Leopard' for its long neck and for having spots!

Camelopardalis is part of the 'Ursa Major' family of constellations.X

The brightest star in Camelopardalis is Beta Camelopardalis, a yellow G-type Supergiant.

Voyager 1, a space probe sent out a while ago, is actually headed toward this area, but I don't think we'll see it because it'll take a long time to get here.

It would be sad if the air I breathe is poisonous to ELF!

The Lynx, is named after the Lynx, a kind of medium sized wild cat.

The Lynx is of the 'Ursa Major' family of constellations.

We are now headed to Alpha Lyncis. It is roughly 55 times the Sun's radius. It is a variable star, meaning that it fluctuates in brightness.

NGC 2419 is a globular cluster also inaccurately named 'Intergalactic Wanderer' because it was thought to not be orbiting around our Milky Way when it actually was./

There are no Messier Objects in Camelopardalis.

Does ELF need to breathe? I wonder if ELF can survive in space outside the craft?

Cancer is named after the Crab. Decapod crustaceans of the infraorder Brachyura. Ok yes I got that from the database I didn't memorise that!3

Cancer is of the 'Zodiac' family of constellations.

Beta Cancri, the brightest star in Cancer, is our next destination. It is a K-Type giant, orange in color. It seems to have a planet orbiting it every 605 days.R

The Delta Cancrids are a meteor shower that occur from December 14 to February 14.

Cancer has two Messier Objects. They are M44 and M67, both open clusters.

Are there seas in ELFs homeworld? Do they have marine animals as well?

Leo is a constellation named after the Lion.2

Leo is from the 'Zodiac' family of constellations.

Alpha Leonis, or Regulus, is the brightest star in Leo. It's actually made up of stars Regulus A, B C and D.

Regulus A, one of the stars that make up the Regulus star system, is a spectroscopic binary, so I consider Regulus as made up of 5 stars!

The Leonids are meteor showers that occur in November. It's material comes from Comet Tempel-Tuttle.g

I cannot find records of a Nebula L77 in this constellation, but it's stuck in my head for some reason.

Leo has five Messier Objects, M65, M66, M95, M96 and M105, all galaxies.M

Is ELF a scientist? An explorer? Is it working? Or is it just having fun now?

Leo minor means 'smaller lion', in comparison to Leo, who is the bigger lion! Small or big, Lions are awesome anyway.

Leo Minor is of the 'Ursa Major' family of constellations.

The brightest star in Leo Minoris is 46 Leonis Minoris. It's also known as Praecipua, meaning 'The Chief'.

Hanny's Voorwerp is a quasar ionisation echo found in Leo Minoris. It is like a large area of gas that has a hole over 16000 light years across in its middle.

Ursa Major means the Great Bear, in contrast with Ursa Minor, the Little Bear. It is also commonly known as the Big Dipper.

Ursa Major is the third largest constellation behind Virgo and Hydra.

Ursa Major is the namesake of its own family of constellations.

Epsilon Ursae Majoris, or Alioth, is the brightest star in Ursa Major. It is also one of the 57 navigational stars.

The Navigational Stars are 57 stars used on earth for celestial navigation.

Ursa Major has seven Messier Objects. M81 and M101 are spiral galaxies, M108 and M109 are barred spiral galaxies, M82 is a starburst galaxy, M40 is a Double Star, and M97 is a planetary nebula.

A Barred Spiral Galaxy is a flat rotating disk of stars, gas and dust with a central bar shaped structure composed of stars. Our Milky Way is one!

I've tried it more times, but it seems like ELF doesn't read my thoughts, but can 'see' my visualisations and feel my emotions. Hmmm.

Canes Venatici is latin for 'hunting dogs', representing the dogs of Bo

tes the Herdsman.

Canes Venatici is of the 'Ursa Major' family of constellations.

We are on course to the binary star Alpha Canum Venaticorum, also known as Cor Caroli.

The largest void ever observed, the Giant Void, is found in Canes Venatici. It is over 1 billion light years across!n

Canes Venatici has five Messier Objects, M51, 63, 94 and 106, all spiral galaxies, and M3, a globular cluster.

It seems like ELF can transmit its intent to me. Just like when I first met ELF, it soothed my worries with its own feeling of peaceful intent.

Coma Berenices means 'Berenice's Hair' in Latin, in reference to Queen Berenice II of Egypt, who offered her hair to the gods for her King's safe return from war.

Coma Berenices is of the 'Ursa Major' family of constellation.

Coma Berenices is the only one of the 88 modern constellations named after a historical figure.

Beta Comae Berenices, the brightest star in this constellation, is a main sequence dwarf star that is close to our sun in size and brightness!

Coma Berenices has eight messier Objects! They are M64, 85, 88, 91, 98, 99, 100, all galaxies, and M53, a globular cluster.

Is that hair on ELF's head? I can't really tell...

tes is represented by a herdsman.

tes is of the 'Ursa Major' family of constellations.x

Alpha Bo

tis, also named Arcturus, is the fourth brightest star seen from earth. It's a 7.1 Billion year old Red Giant.j

If you were alive and we both thought of a different image to ELF at the same time, would it get confused?

Virgo is Latin for Virgin.

Virgo is of the 'Zodiac' family of constellations.

Virgo's brightest star is Spica, or Alpha Virginis. It is a spectroscopic binary whose stars are both egg shaped because they are so close together.

Virgo has eleven Messier Objects. M49, 59, 60, 87and 89 are elliptical galaxies, M58 is a barred spiral galaxy, M61, 90 and 104 are spiral galaxies and M84 and 86 are lenticular galaxies.

Elliptical Galaxies are galaxies that are sort of ellipsoidal, for example, a slightly flattened ball, without much structure other than that stars are orbiting around the centre.

Lenticular Galaxies are disc galaxies that have lost most of their matter. Hmmm, they may also be less flat than spiral galaxies.

I'm going to try to think of different things when ELF zips by!

The Corvus constellation is represented by the raven or crow.

Corvus is of the 'Hercules' family of constellations.

Gamma Corvi is the brightest star in Corvus, it is a binary star made up of Gamma Corvi A, also known as Gienah, and Gamma Corvi B.

We are going back past the ecliptic down to the southern hemisphere of constellations!

ELF just zipped past, and I visualised another UFO right behind it, and ELF turned around for a moment!

Crater is a constellation meaning...cup! Well that's because 'Crater' is 'Cup' in Latin.:

Crater belongs to the 'Hercules' family of constellations.

This time, we are heading toward Delta Crateris. It is an evolved giant star that is rotating so slowly it might as well have a rotational velocity of 0.0km/h.

I was thinking of our favourite hangout to look at the stars, and I started to miss the place. ELF happened to come by and reached out its hand, but before I could reach out, it cocked its head to one side and flew off...

Sextans is a constellation represented by the Astronomical Sextant, a device used for measuring the position of stars.

Sextan belongs to the 'Hercules' family of constellations.

Alpha Sextantis is the brightest star in Sextans. It is an A-type giant star, with 4.5 times the Sun's radius.

What does ELF use to navigate the stars? Does ELF have this super big map of the local group?

The Hydra constellation is represented by a water snake. It is the largest constellation by area, and also the longest one.

Hydra is from the 'Hercules' family of constellations.

Alpha Hydrae, or Alphard, is the brightest star in Hydra. It is about 420 million years old, and has 50 times the Sun's radius.

Hydra has three Messier Objects, M48, an open cluster, M68, a globular cluster, and M83, the Southern Pinwheel Galaxy.

I wonder if I could find a better way to communicate with ELF? Maybe if I imagined a word and what it is visually?

The Pyxis constellation is represented by a Mariner's Compass, because it is actually short for Pyxis Nautica in Latin.

Pyxis is of the 'Heavenly Waters' family of constellations.

Alpha Pyxidis, fated to go Supernova one day. This is the brightest star in Pyxis, and it has 10 times the mass of our Sun.

ELF came by, and I thought of the word 'Apple' while thinking of an apple, really really hard, and ELF stared at me for a moment...and flew off.J

Aah. Puppies and Pixies at the river of milk. We're finally here to visit.

The Pyxis Globular Cluster lies in the galactic halo of the Milky Way, around 133000 Light Years away from the centre of the Milky Way.

The Antlia constellation is represented by an Air Pump. If I remember, specifically one invented by a physicist by the name of Denis Papin.

Antlia is of the 'La Caille' family of constellations.

We are on course to Alpha Antliae, a K-type giant star with 53 times the radius of our Sun.

I held up two pictures of an orange and an apple when ELF flew by, and I thought hard about the word 'Apple'. ELF pointed at the apple!

The constellation Vela means 'Sail' in Latin, named so when it was once part of a larger constellation called Argo Navis, a Ship.

Vela is from the 'Heavenly Waters' family of constellations.^

Gamma Velorum, the brightest star in Vela, is actually a star system with at least four stars.

The Vela Pulsar was the first pulsar to be identified optically. It is in the Vela Supernova Remnant. It spins 11.195 times a second!

A Pulsar is like a...Pulsing Quasar. It's a highly magnetised rotating neutron star or white dwarf that emits a beam of electromagnetic radiation.

ELF came back and hovered there for a moment, looking at me. I was suddenly thinking of an apple!

Ah, Puppis. Like Vela, Puppis was part of the Argo Navis, and Puppis means the 'Poop Deck'.

Puppis is of the 'Heavenly Waters' family of constellations.

The brightest star in Puppis is Zeta Puppis. It's one of the most luminous stars in the sky because it is a rare Blue Supergiant, or an O-Type main sequence star.

The three Messier Objects in Puppis are M46, M47 and M93, all open clusters.W

I would have brought animal companions if I didn't think they'd feel cooped up in here.

Unfortunately 'Puppis' doesn't refer to 'Baby Dogs' or it will be cutest constellation. Right now the cutest one is Lepus the hare.

I've been randomly thinking out words and things to ELF as it zips by. I wonder how much it's absorbed?

Canis Major means 'Greater Dog', named to contrast with Canis Minor, the 'Lesser Dog'.

Canis Major is of the 'Orion' family of constellations.

Sirius! The brightest star in Earth's night sky! It's also designated as Alpha Canis Majoris and also called the 'Dog Star'. Alpha Dog indeed!

Sirius is a binary star, so when we get there near the main star Sirius A, we should try to look out for Sirius B.

Sirius is part of the Winter Triangle asterism, along with Procyon and Betelgeuse. We'll be visiting them soon as well!

Canis Major has one Messier Object, M41, it is an open cluster.

I tried to think of my face and my name at ELF, I wonder if it knows my name by now?

Monoceros sounds like Rhinoceros but is actually Greek for 'Unicorn'! Pardon my frivolous manner in saying that.5

Monoceros is of the 'Orion' family of constellations.

Beta Monocerotis is a triple star system,

NGC 2264 is an interesting one! It's a Cluster of Stars that look like a Christmas Tree, and a Cone shaped Nebula that seems to be balancing above it!

The Messier Object in Monoceros is M50, an open cluster.

ELF stopped right outside again and looked in my direction. I slowly saw the image of myself, but there was a sound building in my head, and I heard 'Stella'!

Canis Minor means 'Lesser Dog'. It's smaller in size compared to Canis Major.

Canis Minor is of the 'Orion' family of constellations.

Procyon is a binary star, and the brightest star in Canis Minor. It's part of the Winter Triangle asterism, together with Sirius and Betelgeuse.r

I don't know if ELF knew how happy I was that it communicated with me. But if can sense my feelings I bet it does!

Gemini is represented by a pair of twins, and is associated with Castor and Pollux from Greek mythology.3

Gemini is of the 'Zodiac' family of constellations.

The brightest star in Gemini is Pollux, but is designated as Beta Geminorum. The second brightest star is Castor, but is designated as Alpha Geminorum.

There is a planet orbiting Pollux, and it has a mass 2.3 times that of our biggest planet, Jupiter!

The Geminids are meteor showers caused by an asteroid instead of a comet.

Gemini's Messier Object, M35, is an open cluster.

I thought out to ELF again, and I pictured myself and my name, and a picture of ELF. It seemed like it was thinking for a while, but flew away.

Auriga is the Latin word for 'Charioteer'. It's associated with several mythological charioteers from Greece.

Auriga is of the 'Perseus' family of constellations.

Alpha Aurigae, or Capella, is a system of four stars, two bright yellow giant binaries and two small red dwarf binaries, orbiting each other.

Auriga has three Messier Objects, M36, 37 and 38. They're all open clusters.

ELF zipped close, and pointed at me, and I heard 'Stella'. It pointed at itself, and I felt a buzz in my head, but didn't really hear anything. ELF looked lost in thought for a while, then left.

The Perseus constellation is named after the Greek mythological hero, Perseus.

Perseus is the namesake of its own family of constellations.b

Alpha Persei, or Mirfak, is the brightest star in Perseus. It is a yellow-white F-type supergiant.

I know right off the bat, that if we had been going to Algol, you would have insisted calling it 'Ra's Al Ghul' instead of 'Algol', 'Beta Persei', or 'Demon's Head'.

Perseus has two Messier Objects, M34, an open cluster, and M76, a planetary nebula also called the Little Dumbbell Nebula.

ELF is still trying to tell me its name, but I can't hear it. Maybe it's just unpronounceable?

Cassiopeia is named after Queen Cassiopeia from Greek mythology. She's the mother of Andromeda, who also has a constellation named after her.

Cassiopeia is of the 'Perseus' family of constellations.

Alpha Cassiopeiae is the brightest star in the Cassiopeia constellation. It is an orange giant star, and is cooler than our Sun.C

Cassiopeia's Messier Objects, M52 and M103, are both open clusters.

I was staring out into space when I felt a presence, and the image of ELF popped into my mind. It appeared right after. Was this ELF's way of announcing its arrival?

Andromeda is a character from Greek mythology who was chained to rocks to be eaten by Cetus. That's why she's also represented as a chained woman.

Andromeda is of the 'Perseus' family of constellations.

Alpha Andromedae is a binary star. It easily looks like one star because the two stars orbit each other closely.e

The three Messier Objects here are M32 and M110, dwarf elliptical galaxies, and M31, a spiral galaxy.

Dwarf Elliptical Galaxies are elliptical galaxies that are smaller than usual elliptical galaxies.

ELF and I are starting to 'speak' in simple sentences now. I'm sure ELF is accommodating me because we're using an Earth language!

Triangulum is a constellation based on the shape, the Triangle. It's the most straightforwardly named constellation I think.s

The three brightest stars, Alpha, Beta and Gamma Trianguli make the 'Triangle' that got the constellation its name.

Triangulum is of the 'Perseus' family of constellations, but has nothing to do with stories regarding Perseus.

The brightest star is Beta Trianguli, a binary star system with an apparent magnitude of 3.00

M33, a spiral galaxy, is the only Messier Object in Triangulum. It's also known as the Triangulum Galaxy.

Learning to communicate with ELF is a unique challenge! Explaining emotions and their words are easier, because ELF can feel my thoughts!

Pisces is Latin for 'Fish' in the plural form.

Pisces is from the 'Zodiac' family of constellations.

The brightest star in Pisces is Eta Piscium, a G-type star./

Pisces has Messier Object M74, a spiral galaxy.

Trying to teach ELF words related to physical sensations is difficult! I tried to convey the word 'Smelly' but I didn't know what to think!

Aries is represented by the ram. It's name is Latin for 'Ram' as well. Sheep are cute!

Aries is of the 'Zodiac' family of constellations.

We are heading toward Alpha Arietis, or Hamal. It is a K2 III CA-1. Which means it is one of the hotter orange giant stars.

Through different examples ELF and I have managed to communicate simple words. Sometimes it says "I am here" just as it arrives, sometimes it says "Hello Stella".

The Taurus constellation is named after the Bull.

Taurus is of the 'Zodiac' family of constellations.

The brightest star in Taurus is Alpha Tauri, or Aldebaran. It is a K5 III star, which means, It's a moderately hot orange giant.

Pioneer 10, a space probe launched from earth in the 1970's, is on the way to Aldebaran as well. but it will reach here only in 2 millions years time.

Two Messier Objects are in Taurus, M1, a supernova remnant also known as the Crab Nebula, and M45, an open cluster known as the Pleiades.

One thing I've noticed is that ELF learns fast! I'm probably the one not 'thinking' up new words and information for it quick enough!

Orion is based on the hunter Orion from Greek Mythology.>

Orion is the namesake of the 'Orion' family of constellations.

We are heading toward Rigel. It is a multiple star system, with the main one, RIgel A, being a Blue-White Super Giant.

The Orionid meteor showers occur in October. The meteor's parent body is Halley's Comet, a comet that goes by earth every 74 to 79 years.

Orion has three Messier Objects, M42 and M43, both H II regions, and M78, a diffuse nebula. I wonder if there are giant aliens in M78.

ELF tried again to tell me its name. All I heard was "My name is" and the weird buzzing sound happened again.

Lepus is a constellation named for the 'Hare'.

Lepus is of the 'Orion' family of constellations.

Alpha Leporis is an F0 lb star, which means it is a yellow-white, less luminous supergiant star.6

Lepus has one Messier Object, M79, a globular cluster.

I asked ELF "Where are you from?" ELF replied with "I am from...", and the buzzing was in my mind again, but at least I saw a vague image of a spiral barred galaxy.

The Columba constellation is named after the Dove.

Columba is of the 'Heavenly Waters' family of constellations.

We are on course for Alpha Columbae, or Phact. It is a B7 IV star, so it's a Blue-White Subgiant.

ELF came by. It thought to me 'My name is...ELF.' And then gave a thumbs up. I think it didn't want me to worry about it too much!

Caelum is a constellation that is Latin for 'Chisel'. It's also the blueprint name for the Enhancement Drone!

Caelum is of the 'La Caille' family of constellations.

Alpha Caeli is an F2V star, which means it is a yellow-white main sequence star.u

It is easier to communicate telepathically with ELF now, but it still isn't as smooth as holding a real conversation!

Horologium is represented by a Pendulum Clock.

Horologium is from the 'La Caille' family of constellations.<

Alpha Horologii is a K2 III star, An Orange hued Giant Star.

The Reticulum constellation is represented by the Reticle, in this case, meaning the crosshairs on the focus of a sighting device.

Reticulum is of the 'La Caille' family of constellations.

The brightest star is Alpha Reticuli, aG8 II-III star.

Dorado is Portuguese for 'Dolphinfish'. It's not a Dolphin however, it's really a fish!

Dorado is from the 'Bayer' family of constellations.c

We heading straight to Alpha Doradus, which happens to be one of the brightest binary stars around.

Most of the Large Magellanic Cloud is in Dorado, it is a satellite Galaxy of the Milky Way and...we have plans to head there!

Dorado is where the South Ecliptic Pole is. So if we are in Dorado and we look straight at Earth, we'll be looking at the South Pole!

Pictor is represented by the painter's Easel. 'Pictor' itself is short for 'Equuleus Pictoris', which means 'Painter's easel'.

Pictor is of the 'La Caille' family of constellations.

When we reach Alpha Pictoris, we'll look toward Mars. We won't see it but we know we're looking at its south pole!

Carina is Latin for 'Keel' of a ship. And we are finally going to the third and final part of the Argo Navis!

Carina belongs to the 'Heavenly Waters' family of constellations.

Canopus is the brightest star in Carina. It is also the second brightest star in the night! It is an A9 II star, so it is a white giant.

Volans is represented by a Flying Fish. Some old maps had Volans being chased by Dorado, next to the Argo Navis.7

Volans belongs to the 'Bayer' family of constellations.

Beta Volantis is a K1III star, so it is a giant orange. Haha did I just say that I meant orange giant!...Star!

Mensa is Latin for Table. It's actually short for Mons Mensae, an actual mountain in South Africa, so it means, and is represented by the 'Table Mountain',

Mensa is the last of the 'La Caille' family of constellations we are visiting.

Alpha Mensae is the brightest star in Mensa. It is a G7 V star, so it is a Yellow main sequence star, almost like our Sun!

This is really it! I can't believe we came this far! The last of the 88 constellations! Unbelievable...

ELF and I were just discussing about the nature of the universe. At least, I tried to, I think theres too many advanced concepts that are not easily communicated across to me!

The Large Magellanic Cloud is a galaxy that orbits the Milky Way. It is an irregular galaxy and has a lot of star formation activity within it.

Kree! I'm so excited! We're going to another galaxy! Oh what a Flood of emotions.

The Small Magellanic Cloud is 75000 light years away from the Large Magellanic Cloud, but they are gravitationally bound and have a bridge of gas in between them.

When we are at the Large Magellanic Cloud, we can look toward the Milky Way and see the entirety of it! It's going to be super big and super bright!K

There's almost nothing for light years around, where does ELF disappear to?

The 'Local Group', is a group of over 50 galaxies, with its gravitational centre somewhere between our Milky Way and the Andromeda Galaxy.

The Magellanic Clouds are named after Ferdinand Magellan, who made it more well known to the general public.

The Andromeda Galaxy contains One Trillion stars! It's the largest Galaxy in the Local Group.

A few billions years from now, the Andromeda Galaxy will merge with our Milky Way. It's by no means going to be a peaceful merge though./

The Andromeda Galaxy is a barred spiral galaxy.

The Andromeda Galaxy is named so because it is within the Andromeda Constellation.

The Cigar Galaxy is a Starburst Galaxy. That means that there is a large amount of star formation going on in the galaxy.

The Cigar Galaxy is named as such because it is long and shaped like a cigar.

The Cigar Galaxy is number 82 of the Messier Objects, or just M82.

M82 is in the Ursa Major constellation

ELF and I were just discussing about the nature of the universe. At least, I tried to, I think theres too many advanced concepts that are not easily communicated across to me!

The Pinwheel Galaxy, or M101, is in the Ursa Major constellation.

The Pinwheel Galaxy sort of looks like a pinwheel! If you look closely it seems like its four spiral arms are spaced out nicely.c

M101 is the namesake of the M101 Local Group, which includes a few other companions of M101 itself.

The Pinwheel Galaxy has a diameter of 170,000 light years!

We think there are one trillion stars in the Pinwheel Galaxy, but I don't think anyone is going to count them one by one to prove it. Wait maybe ELF knows...

The Sombrero Galaxy, or M104, is in the Virgo constellation.{

The Sombrero Galaxy is named as such because there is a dust lane that surrounds a large bulge in the middle of the galaxy.

I was already in awe of the rings around Saturn. I cannot imagine how the dust lane of the Sombrero Galaxy is like that, but around an entire galaxy!

The Sombrero Galaxy is about 50 thousand light years in diameter, about one third of the Milky Way.

M51a is also known as the Whirlpool Galaxy. Its in the Canes Venatici constellation. It also has the name Typhon Canum Venaticorum.

M51a is interacting with M51b, a Dwarf Galaxy. It is believed that M51b passed through M51a 500 Million years ago.

NGC1300 is a barred spiral galaxy in the Eridanus constellation.&

NGC1300 is 110,000 light years across!

NGC 1300 looks like it has a spiral within a spiral.

The Tadpole Galaxy looks like a tadpole because it is a barred spiral galaxy that has been disrupted by a smaller galaxy that caused it to force out a trail of stars, gas and dust.1

The Tadpole Galaxy is in the Draco constellation.

The tail of the Tadpole Galaxy is 280,000 light years long!

I asked ELF if the Tadpole Galaxy was special, but ELF remarked that it's common throughout the universe.

Hoag's object is in the Serpens Caput constellation.E

Hoag's object has a ring of hot blue stars circling a yellow nucleus.
