Blue Skies and Water Ice on Pluto
We’re getting a first look at blue skies and water ice from Pluto. These images come from NASA’s New Horizon Spacecraft, which is studying Pluto and its moons. Researchers say Pluto’s “Blue Sky” tells scientists about the size and composition of the dwarf planet’s haze particles. The particles appear to be larger than the ones around Earth. As for the “Water Ice,” New Horizons detected numerous small, exposed regions of water ice on Pluto. But it’s not clear why the water appears exactly where it does.
