It's not entirely clear how neighboring planet Mars went from a presumably life-supporting planet to a place as dead as all others in the solar system. We do know, however, that whatever water and ...

NASA’s MAVEN spacecraft has confirmed, through nearly a decade of orbital observations, that solar wind physically strips gas from Mars’ upper atmosphere in a process called sputtering. That finding ...

A phenomenon, thought impossible on Mars, compresses its atmosphere like squeezing a tube of toothpaste. Dubbed Zwan-Wolf, this effect was known on Earth but never observed elsewhere.

Deep oceans of magma once sloshed about inside the crust of Mars, seismic measurements taken by NASA's InSight mission ...

Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the red planet's surface, billions of years ago. And if there was water, there must also have ...

New research suggests Mars' missing atmosphere -- which dramatically diminished 3.5 billion years ago -- could be locked in the planet's clay-covered crust. Water on Mars could have set off a chain ...

The rusty world is full of mysteries—and some of the solar system's most extreme geology. Learn more about Earth's smaller, colder neighbor.

During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as ...
