On Earth, these kinds of markings are usually linked to microbial life. Could this be true for Mars?

Mars has captivated scientists and the public alike for centuries. One of the biggest reasons is the planet’s reddish hue, earning the fourth rock from the sun one of its most popular nicknames — the ...

One of the great unsolved problems in modern planetary science is written on the surface of Mars. Mars has canyons that were carved by rivers, so it was once warm enough for liquid water. How—and ...

Most planetary scientists agree that Mars’ extreme conditions would be uninhabitable to life as we know it. New research, however, suggests that we might be underestimating the hardiness of lichens.

While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet's surface. Through computer modeling, the ...

Mars, long painted as a frozen desert, is starting to look more like a planet that once knew the feel of warm rain and flowing water. A new wave of research argues that the Red Planet may have spent ...

Researchers from the University of Oxford have uncovered evidence that Mars once hosted enormous, Earth-like magmatic systems ...

A study published last year in the journal Science suggested liquid water is present beneath the south polar ice cap of Mars. Now, a new study in the AGU journal Geophysical Research Letters argues ...

New research suggests Mars could have enough water under its surface to form a global ocean. On Monday, scientists released their findings, which are based on seismic measurements captured from NASA’s ...

Scientists have detected complex organic matter in an ancient river valley on Mars, specifically within Jezero Crater. This ...
