A dark patch in Mars' Utopia Planitia region has grown significantly since it was first photographed in 1976. Scientists have a loose understanding of what it is, but they can't properly explain its gradual growth.

Scientists have long known that fungi are resilient, but a new study suggests that some strains might survive every step of the long, brutal trip to Mars. In a paper published in Applied and Environmental Microbiology,

In early 2026, a photo circulated online that claimed to authentically show a blue sunset on Mars. The earliest version of the image that Snopes could find came from a Facebook pa

A new image shows a striking contrast between Mars' desert-like terrain against dark deposits of volcanic ash.

Observations by the Mars Express orbiter reveal rapid changes on the Red Planet’s surface from windblown volcanic ash

In its journey to a crater named Antofagasta, the Curiosity rover has discovered a strange texture patterning rocks on the planet's surface. To our eyes, the pattern looks like reptilian scaling, as if a dragon once lay in the mud.
