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.
The closer the New Horizons spacecraft gets to Pluto, the more puzzling the dwarf planet becomes.
An unmanned NASA spacecraft whizzed by Pluto on Tuesday, making its closest approach in the climax of a decade-long journey to explore the dwarf planet for the first time, the US space agency said.
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.
There's a near-perfect heart shape on Pluto's rusty red surface which scientists are seeing for the first time as a piano-sized NASA spacecraft, New Horizons, hurtles toward the distant body on its way toward a historic flyby ...
Come Tuesday, Clyde Tombaugh will pass within 7,800 miles (12,550 kilometers) of the icy world he discovered 85 years ago.
