NASA's Curiosity Mars rover has uncovered a diverse mix of organic molecules on Mars, including chemicals widely considered building blocks for the origin of life on Earth.

Scientists believe they found fresh proof of an ancient ocean on Mars in the form of a “bathtub ring” it left after it dried up billions of years ago.

Organic compounds found in a Martian crater contain building blocks of life, according to a new study.

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.

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

"The possible existence of an ocean suggests that a large body of water may have persisted for a long time. That could have been an important ingredient for life."

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.
