Pluto's moons are weird as hell.

Three of the dwarf planet's five moons — named Charon, Nix, Hydra, Kerberos and Styx — are coming into better focus now that NASA's New Horizons spacecraft is beaming back more images from last week's historic flyby, and man, do they look strange.

New Horizons — which made its close flyby of Pluto on July 14 — has revealed that Nix, Pluto's "jelly bean-shaped" moon has a red spot on it that might be a crater, but scientists won't know the definite cause of the red coloration until the spacecraft sends more of the information it has already gathered to the ground.

“This observation is so tantalizing, I’m finding it hard to be patient for more Nix data to be downlinked,” New Horizons mission scientist Carly Howett said of the enhanced-color image, in a statement.

The color red already seems to be an integral part of the color scheme for Pluto and its moons.

The dwarf planet has a distinctive orangey-red tint, while its largest moon Charon has a red looking north polar region. Scientists aren't yet sure what accounts for the red areas of Charon or Nix, but more data already collected but not yet downlinked from New Horizons should reveal the composition of the different areas, according to NASA.

Pluto's moon Hydra is also getting some attention. The moon, which is about 34 miles long and 25 miles wide, appears to be shaped somewhat like the state of Michigan, NASA said.

A new black and white image — taken on July 14 when New Horizons was 143,000 miles from the moon — also revealed at least two craters on the cosmic body's surface.

“Before last week, Hydra was just a faint point of light, so it's a surreal experience to see it become an actual place, as we see its shape and spot recognizable features on its surface for the first time," New Horizons mission science collaborator Ted Stryk said in a statement.

According to NASA, New Horizons should send images of Kerberos and Styx by mid-October at the latest.

New Horizons is helping scientists on Earth study Pluto like never before. The spacecraft became the first human-made probe to study Pluto and its moons at close range during its closest approach with the dwarf planet, when it came within 7,750 miles of the icy dwarf planet. The spacecraft was traveling more than 30,000 mph when it passed by Pluto, collecting a significant amount of data along the way.

Data from New Horizons has already revealed that Pluto has a nearly 11,000-foot tall mountain range made of water-ice, and likely is geologically active.

New Horizons will now spend more than a year sending back all of the photos and other data it took during the flyby.

Nix and Hydra were both discovered using data from the Hubble Space Telescope in 2005, about a year before New Horizons launched, but these images mark the first time scientists have been able to examine details on the surfaces of the moons.

Researchers also recently used Hubble data to discover that Hydra and Nix tumble in their orbits around Pluto because the gravitational environment created by Pluto and Charon throws the two moons into chaos.
