Blue skies, frozen water detected on Pluto

Pluto has blue skies and patches of frozen water, according to the latest data out Oct. 8 from NASA's unmanned New Horizons probe, which made a historic flyby of the dwarf planet in July.

Never before has Pluto -- a resident of the distant Kuiper Belt, a frigid region of the solar system beyond Neptune that is home to many comets and asteroids -- been observed in such detail.
