Learn why scientists are cautiously optimistic about the potential biosignatures found in the Sapphire Canyon rock sample.

NASA has discovered signs of life on Mars in the form of organic carbon, sulfur, rust, and phosphorous in a canyon, and new research from the University of Texas at Austin suggests that an atmosphere may have formed billions of years ago,

NASA has just shared one of its most impressive Mars panoramas to date. Captured by its trusty Curiosity rover, the panorama (below) of the Martian landscape comprises 44 images taken by the rover’s Mastcam. The color has been adjusted to match the lighting conditions as the human eye would see them on Earth.

Has NASA's Perseverance rover at long last found evidence that life did indeed once exist on Mars? Here's what we know.

NASA scientists say a rock sample collected by the Perseverance rover in Jezero Crater may contain the strongest signs yet of ancient microbial life on Mars, though more analysis is needed before drawing firm conclusions.

Potential signs of microbial life were found in a rock sample collected by the rover in 2024 from an ancient dry riverbed on Mars' Jezero Crater -- an area of rocky outcrops on the edges the Neretva Vallis, a river valley carved by water rushing to the canyon billions of years ago, NASA officials announced in a press conference on Wednesday.

But the claim that NASA announced found life on Mars was false. NASA announced it found promising evidence of potential ancient life on the planet, but more research was needed before scientists could comfortably declare it was definitive evidence of life.

NASA officials say its Mars-bound ESCAPADE spacecraft is back in Florida and is being prepped for its scheduled launch this fall.
