Pluto may be a strange, faraway world, but scientists have learned it shares a familiar trait with Earth -- a blue sky.
The first color images of a thin haze that surrounds Pluto show it to be reflecting a pale blue light, scientists working on NASA's New Horizons mission said Thursday.
"Who would have expected a blue sky in the Kuiper Belt?" said the mission's principal investigator, Alan Stern, referring to the region at the edge of the solar system that includes Pluto. "It’s gorgeous."
