By aiming intense X-ray beams at iron samples, scientists have studied the cores of “super-Earth” planets triple the size of Earth. The team, led by…
Mercury is small, fast, and close to the sun, making the rocky world challenging to visit. Only one probe has ever orbited the planet and…
Saturn’s rings display their subtle colors in this view captured on August 22, 2009, by NASA’s Cassini spacecraft. The particles that make up the rings…
Hydrogen sulfide, the gas that gives rotten eggs their distinctive odor, permeates the upper atmosphere of the planet Uranus – as has been long debated,…
This image of Jupiter’s iconic Great Red Spot and surrounding turbulent zones was captured by NASA’s Juno spacecraft. The color-enhanced image is a combination of…
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant…
As Curiosity rover marches across Mars, the red planet’s watery past comes into clearer focus. In early 2017 scientists announced the discovery of possible desiccation…
Fragments of a meteorite that fell to Earth more than a decade ago provide compelling evidence of a lost planet that once roamed our solar…
Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) mission. The origin…
“The directive I am signing today will refocus America’s space program on human exploration and discovery. It marks a first step in returning American astronauts…
Planets orbiting “short-period” binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars’…
