Scientists with NASA's Mars orbiters have been waiting years for an event like the current Mars global dust storm.

Twelve new moons orbiting Jupiter have been found—11 “normal” outer moons, and one that they’re calling an “oddball.” This brings Jupiter’s total number of known moons to a whopping 79.

Juno’s JIRAM instrument points to a new heat source close to the south pole of Io that could indicate a previously undiscovered volcano.

Three of the world's largest radio telescopes have revealed that a near-Earth asteroid discovered last year is actually two objects, nearly equal in size, orbiting each other.

New research from NASA's Cassini spacecraft's up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its rings and its moon Enceladus

A dust storm continues to envelop the Red Planet and Curiosity's labs are back in action.

NASA’s Dawn spacecraft reached its lowest-ever and final orbit around dwarf planet Ceres on June 6 and has been returning thousands of stunning images and other data.

A new study uses Earth as a stand-in for an exoplanet and shows that even with very little light -- as little as one pixel -- it is still possible to measure key characteristics of distant worlds.

Mission controllers have turned off the industrious ion engines on NASA’s Dawn spacecraft for the last time and do not expect to turn them back on again, if everything goes as planned for the rest of Dawn’s mission.

Data from NASA's Cassini spacecraft reveal complex organic molecules originating from Saturn’s icy moon Enceladus, strengthening the idea that this ocean world hosts conditions suitable for life.

A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA’s Opportunity rover to suspend science operations. But across the planet, NASA’s Curiosity rover, which has been studying Martian soil at Gale Crater, is expected to remain largely unaffected by the dust.

A new multiagency report outlines how the U.S. could become better prepared for near-Earth objects—asteroids and comets whose orbits come within 30 million miles of Earth—otherwise known as NEOs.
