Pluto is "spray painting" Charon red!

X-rays aren't the only puzzle surrounding Pluto's atmosphere. After a year studying the data and images sent back from New Horizons, the mission scientists think they've solved the mystery of the red-tinged polar region on Pluto's largest moon, Charon. Methane is escaping from Pluto's atmosphere and is captured by Charon's gravity, where it settles in the icy regions at the poles. The red color is created when that methane is exposed to sunlight and molecules called tholins are formed, much like the methane snow-capped mountains seen on Pluto itself.
