New experiments have shown that the core of Mars formed much faster than Earth's core, thanks to molten iron and nickel sulfides seeping down through solid rock and into the center of the Red Planet.

Mars has a solid inner core, according to a new study published in Nature. Using seismic data from NASA’s InSight lander, researchers identified a dense, solid core about 600 kilometers wide, ...

Mars is known for its barren desert landscape and dry climate. But two recent studies in the journals Nature and Science go beneath the surface,... The core of Mars looks like Earth’s. What makes the ...

Three years ago, Martian dust shrouded the solar panels on NASA’s InSight lander, preventing further operations and leading to its retirement. But the mission’s data continues to reveal information ...

A clay-rich mesa in the Hellas basin of Mars. The blue color near the rim is aluminum bearing clays. The red-orange color below that is iron and magnesium bearing clays. The image captures an area ...

It's time now for our science news roundup from Short Wave, NPR's science podcast. I am joined by the show's two hosts, Regina Barber and Emily Kwong. Hi, y'all. EMILY KWONG, BYLINE: Hi. REGINA BARBER ...

Unravelling the interior structure of Mars is critical for understanding its geological evolution and current dynamical processes. Mars seismology investigates the generation, propagation and ...

The thick, mineral-rich layers of clay found on Mars suggest that the Red Planet harbored potentially life-hosting environments for long stretches in the ancient past, a new study suggests. Clays need ...

Mars’ Jezero Crater holds signs of ancient water and strange mineral reactions, some linked with organic compounds. With Perseverance’s samples and AI-refined mineral maps, scientists are closing in ...
