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.

A huge geological structure on Mars resembling a bathtub ring may be evidence of an ocean that once covered a third of the Red Planet.

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.

NASA's Curiosity rover has identified more organic compounds as scientists investigate any potential ancient life signs on Mars. It was exploring the massive Gale Crater also believed to be a now-dry lake.

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

NASA's Curiosity Rover discovered a large cluster of polygonal rocks on the planet of Mars, which may indicate evidence of water.
