Nasa Space Iquiry

Around a year ago Nasa's latest space craft caught a photo of Pluto's biggest moon, Charon, had turned red. For a long time scientists didn't know what it was but after a while of studying, a whole year, they figured out that there was gas escaping from Pluto. At first one scientist thought that the entire crust of Pluto had been split open. The scientists were happy since it took a very long time to figure out.
