The blue-toned rocks in the upper-left of the image are depleted in iron because it was removed during weathering on ancient Mars. This is geological…
Brown dwarfs are often called “failed stars.” They form like stars but are not massive enough to fuse hydrogen into helium as stars do. More…
A view from the “Kimberley” formation on Mars taken by NASA’s Curiosity rover. The strata in the foreground dip towards the base of Mount Sharp,…
Neptune and Uranus are the outermost two planets of our solar system and two gas giants. Credit: NASA Uranus and Neptune both have a completely…
The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA’s Juno spacecraft allowed scientists to discover faint aurora features likely triggered by charged particles coming from…
The first X-rays from Uranus have been captured by Chandra during observations obtained in 2002 and 2017, a discovery that may help scientists learn more…
Raised ridges spidering across the floor of a Martian crater were likely created by runoff from a long-lost glacier that once draped the planet’s southern…

When flying past Venus in July 2020, Parker Solar Probe’s WISPR instrument, short for Wide-field Imager for Parker Solar Probe, detected a bright rim around…
An illustration showing how a combination of static high-pressure synthesis techniques and dynamic methods enabled the researchers to probe the magnesium silicate bridgmanite, believed to…
“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon…
