Pluto has blue skies and patches of frozen water, according to the latest data out Thursday from NASA's unmanned New Horizons probe, which made a historic flyby of the dwarf planet in July.
The head of NASA appealed to Congress on Friday to put more money into restoring America's ability to send astronauts into space instead of relying on Russian rockets.
A spacecraft the size of a shoebox with Arizona origins will soon be orbiting our nearest neighbor to create a map of water-ice on the moon.
Enceladus looks as though it is half lit by sunlight in this view from NASA's Cassini spacecraft, but looks can be deceiving. The area on the right, where surface features can be made out, are actually illuminated by light ...
The closest-yet views of Ceres, delivered by NASA's Dawn spacecraft, show the small world's features in unprecedented detail, including Ceres' tall, conical mountain; crater formation features and narrow, braided fractures.
NASA's Dawn spacecraft spotted this tall, conical mountain on Ceres from a distance of 915 miles (1,470 kilometers).
On July 9, 2015 the four spacecraft of NASA's Magnetospheric Multiscale, or MMS, mission began flying in a pyramid shape for the first time. The four-sided pyramid shape—called a tetrahedron—means that scientists' observations ...
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 ...
Vast frozen plains exist next door to Pluto's big, rugged mountains sculpted of ice, scientists said Friday, three days after humanity's first-ever flyby of the dwarf planet.
