Scientists Discover Outer Space Isn't Pitch Black After All
Scientists have used a NASA probe way out in space, beyond Pluto, to measure visible light that's not connected to any known source like stars or galaxies.

PHOTOS: These Images Were Captured Nearly 3.8 Billion Miles From Earth
The distance marks a record: the farthest from Earth an image has been taken. Before NASA's New Horizons probe caught these glimpses in December, the 1990 "Pale Blue Dot" image had held the record.
NASA Releases New Video Showing Higher-Resolution Closeup Of Pluto
The best photos from the New Horizons spacecraft that buzzed Pluto earlier this year are now making their way back to Earth, providing resolutions of less than 100 yards per pixel.
Distant Pluto Comes To Life
When a probe skimmed past the dwarf planet in July, researchers expected to see a cold, dead world. New results published today show that Pluto is an active place.
Why Is The Sky Blue? (On Pluto, That Is)
Pluto's atmosphere has a blue haze, in a new photo from the New Horizons probe. But the particles causing that color are probably gray or red — and the planet's surface has red ice.
NASA's New Pluto Images Point To Geologically Active World
The latest photos show ice plains that appear to be only 100 million years old and a hilly region that could be what is left when surrounding material is eroded away.
On The Cold, Dead Fringes Of The Solar System, Pluto Looks Shockingly Lively
New Horizons team scientist Carly Howett says no one expected the kind of geologic activity that the spacecraft appears to have found on the dwarf planet and its moon.
NASA Zooms In On Pluto, For Closest Views Yet
New images of Pluto are beginning to arrive from NASA's space probe, and they're already allowing scientists to update what we know about the dwarf planet.
Planet Or Not, Icy Pluto To Finally Get Its Day In The Sun
Astronomers kicked Pluto out of the planetary club in 2006 because of its small size. But scientists set to explore the surface Tuesday via a spacecraft's camera say those other guys are just wrong.
Earth Gets A Close-Up View Of Its Most Distant Neighbors
Early Tuesday morning, NASA's New Horizons Spacecraft will complete the first-ever flyby of the dwarf planet Pluto. NPR's Geoff Brumfiel reports live from the New Horizons Control center.
