Mars was once a watery world, with lakes, rivers and a shallow ocean similar to those on Earth. But somewhere between 2 billion and 3 billion years ago, the water dried up after severe climate change.

The discovery was made on the Red Planet's northern polar plains thanks to observations of Mars' gravity by NASA's Insight mission and other satellites in orbit. Map highlighting the dense ...

"Spiders on Mars" is the name given to a geological feature, known as araneiform terrain, that is visible in multiple locations on the Red Planet.In these places, hundreds of dark crack-like ...

Sep. 25, 2024 — 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 ...

Mars spiders have arrived on Earth. But fear not, arachnophobes — these "spiders" aren't actual arachnids, but spider-like geological formations on the Martian surface. And NASA has just ...

The five-year study was conducted by NASA's Jet Propulsion Laboratory. Over two decades since NASA researchers first saw images of mysterious, spider-like formations across the southern hemisphere ...

The red planet Mars, named for the Roman god of war, has long been an omen in the night sky. And in its own way, the planet’s rusty red surface tells a story of destruction. Billions of years ...

China’s historic attempt to bring samples from Mars to Earth could launch as soon as 2028, two years earlier than previously stated, according to a senior mission official. The country’s ...

Now, a new study posits that scientists could potentially detect one of these hypothetical intergalactic travelers as it zoomed through the inner Solar System by measuring a “wobble” in Mars ...

Watching for changes in Mars' orbit over time could be new way to detect passing dark matter, according to researchers. In a new study, MIT physicists propose that if most of the dark matter in ...

A flyby like this, the researchers predict, would introduce a wobble into Mars' orbit, to a degree that today's technology could actually detect. Such a detection could lend support to the idea ...
