Like graffiti sprayed by an unknown artist, unexplained arc-shaped, reddish streaks are visible on the surface of Saturn's icy moon Tethys in new, enhanced-color images from NASA's Cassini spacecraft.
Colorful new maps of Ceres, based on data from NASA's Dawn spacecraft, showcase a diverse topography, with height differences between crater bottoms and mountain peaks as great as 9 miles (15 kilometers).
The crater that contains those puzzlingly bright spots on Ceres may harbor an equally puzzling haze. Or not. The hints of haze on the dwarf planet, seen in some of the images coming from NASA's Dawn spacecraft, add another ...
Japanese space scientists are on the hunt for a new name for an asteroid that may contain the secret of life, with a public competition beginning Wednesday.
The New Horizons spacecraft did what it was meant to do. It explored the unexplored dwarf planet Pluto. So, now what?
Three astronauts living at the International Space Station were forced to scramble to safety after what NASA described as a "close pass" by flying Russian space debris on Thursday.
