Researchers studying material returned from asteroid Bennu report that organic compounds and minerals are clustered into three distinct chemical regions, suggesting that water altered the asteroid in a far more localized

Researchers from Delft University of Technology have outlined KYTHERA, a Venus lander concept designed to survive for up to 200 Earth days while conducting atmospheric, environmental, and geologic science on the surface.

Analysis of returned OSIRIS-REx samples suggests Bennu’s low thermal inertia comes from cracks within its surface rocks, helping explain why the asteroid looked so different up close than it did from Earth.

A research team in China has proposed an integrated system aimed at studying Venus’s extreme atmosphere, framing the concept as a new way to deepen exploration of one of the solar system’s harshest environments.

New complementary observations from the James Webb and Hubble space telescopes are offering one of the most complete views yet of Saturn’s layered and dynamic atmosphere.

NASA has named 10 participating scientists to help design and support lunar surface science for Artemis missions, strengthening the agency’s push to turn crewed Moon landings into a sustained research campaign.

NASA's James Webb and Hubble space telescopes have combined infrared and visible-light observations to produce the most comprehensive view of Saturn ever captured, revealing atmospheric features across multiple altitudes simultaneously.

The James Webb Space Telescope has identified L 98-59 d, an exoplanet with a molten rock ocean beneath its surface that traps enormous amounts of sulfur, creating atmospheric chemistry unlike any known world in our solar system.

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.
