Scientists analyzing NASA InSight seismic data have identified what appears to be a substantial liquid water reservoir 10 to 20 kilometers beneath Mars's surface, potentially rewriting our understanding of Martian habitability.

ESA's Mars orbiters captured unprecedented data as a massive solar storm hit the Red Planet, causing spacecraft glitches and supercharging Mars's upper atmosphere.

Scientists analyzing dust samples returned from asteroid Ryugu by Japan's Hayabusa-2 mission have uncovered a 4.6-billion-year magnetic record that reveals conditions in the earliest days of the solar system.

Scientists have created the first three-dimensional map of Uranus's upper atmosphere using the James Webb Space Telescope, revealing how the planet's bizarre tilted magnetic field creates complex auroral patterns and drives atmospheric cooling. The 15-hour observation session captured faint molecular emissions up to 5,000 kilometers above the clouds.

Mineral analyses near Pavonis Mons show Martian volcanoes evolved through multiple eruption phases, not single events as long assumed.

New analysis of young Martian volcanoes reveals surprising diversity in eruption styles and compositions. It challenges assumptions about Mars geology.
