Lets take a deep dive into this astonishing world of cosmos. Now you are going to read some of the coolest things about this universe.



10.Twilight phenomenon These spectacular phenomenon occurs when the unburnt fuel particles in the rocket trail and water condense, freeze and then expand in the thinner upper atmosphere and illuminated by sunlight. These giant colourful doodles in the sky leave us wondering what their message may be. But before we can decipher it, they’ve already disappeared.







9.cold stars

Yupp you read it right, in this vast cosmos, cold stars do exist.These failed stars are generally called brown dwarfs. The coldest brown dwarf star is known as WISE 1828+2650, this chilly star is not even as warm as a human body, but less then 25 °c.









8.Sun's colour

You will be surprised to know that the colour of our sun is not yellow.It looks yellow to us because the Earth’s atmosphere scatters higher wavelength colors, like red, orange and yellow less easily, but actually all the colours mix up together, which appears to our eyes as white.









7.rogue planets

In space, there are some planets which do not orbit any stars but they orbit the galactic centre directly. These fellow lonely planets have been ejected from their planetary systems, in which they have formed or never been gravitationally bounded with any stars.









6.cold welding

One of the interesting thing about space is that, you don't need any welding machine to joint your metallic mechanical parts. You just have to brought them in contact and they will automatically joint together.no liquid or molten phase is required to joint them.
