Evidence is mounting that the same basic chemistry that made Earth habitable is unfolding, or once unfolded, on Mars. From ...

The surface of Mars is covered in faults and scars which show that the planet was once tectonically active, with activity beneath the surface that formed structures like valleys and trenches. But most ...

This unusual crater on Mars resembles a butterfly, but its shape tells a story of a shallow impact, melted ice, and ancient ...

Mars has lately been experiencing “global auroras” of unprecedented scale as a result of increased solar activity. Auroras are caused when charged particles from the Sun interact with a planet’s ...

If liquid water indeed exists under the south polar ice cap of Mars, it has to be due to volcanic activity, a new study suggests. The researchers behind the new work argued that there needs to be an ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

It seems like we hear big news about Mars almost every day, even though the planet’s only known inhabitants are our trusty rover friends. It’s red and dusty now, but scientists know it had water ...

PROVIDENCE, R.I. [Brown University] — Planetary geologists at Brown University have found a gully fan system on Mars that formed about 1.25 million years ago. The fan offers compelling evidence that ...

There might have been more water on Mars than previously anticipated, according to new data from scientists monitoring China's Zhurong rover on the planet. The discovery of certain cracks and surface ...

The barren landscape of Mars makes the planet seem like a quiet, frozen desert where nothing has happened for billions of years except for the occasional dust storm. New research, however, suggests ...

Significant water activity existed on the surface of Mars until approximately 750 million years ago - the high-frequency ...
