Shortly after unveiling the clearest, most detailed images of Pluto, NASA is sharing the highest resolution images of Nix, one of the dwarf planet's moons.

According to The Washington Post, the new images were available in color and in black and white. Like previous photos New Horizons snapped of Nix, the new ones also show a distinct reddish spot on the moon's surface.

Emily Lakdawalla, senior editor of The Planetary Society, shared the images on Twitter Friday.

New Horizons was not able to stop at Pluto, the dwarf planet on the edge of our solar system, and was thusly not able to travel around to see its moons. Regardless, the images of Pluto's moons are among the best ever taken.

In fact, the new close-up images of Pluto are not only stunningly detailed, but they prove just how geologically complex the dwarf planet is.

"The surface of Pluto is every bit as complex as that of Mars," Jeff Moore, leader of the New Horizons Geology, Geophysics and Imaging (GGI) team at NASA's Ames Research Center in Moffett Field, Calif., said in a news release. "The randomly jumbled mountains might be huge blocks of hard water ice floating within a vast, denser, softer deposit of frozen nitrogen within the region informally named Sputnik Planum."
