NASA’s Perseverance rover has assembled a compelling mineralogical case that Jezero crater on Mars once sustained a warm, wet ...

Mars may have been much warmer and wetter billions of years ago than previously thought, according to new findings from ...

A recent study showed that Mars was warm and wet billions of years ago. The finding contrasts with another theory that this era was mainly cold and icy. The result has implications for the idea that ...

A northern summer dust storm on Mars boosted high-altitude water escape, suggesting short-lived events may play a bigger role ...

Mars, the Red Planet, seems to have had rivers, lakes, maybe even seas. Minerals, channels, and rock formations all hint at ...

Since humans first started observing Mars, the existence of nocturnal ice clouds on the Red Planet has been known, primarily through daytime observations and sophisticated climate models. Twilight ...

Sulfur crystals found inside a rock after NASA’s Curiosity Mars rover happened to drive over it and crush it on May 30, 2024. This discovery supports new research led by scientists at The University ...

Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice ...

The discovery suggests that parts of Mars may once have supported tropical-like climates, complete with heavy, sustained rainfall.

Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position ...

Stephen Kane, a professor of planetary astrophysics at UC Riverside, was skeptical when he read recent studies that showed the gravitational pull from Mars being connected to Earth’s long-term climate ...
