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,

Curiosity is exploring Mars’ boxwork terrain, where ridges and hollows may have formed from cementation and erosion. The rover has been documenting rock textures and chemistry, comparing smoother ridge rocks with nodular hollow-edge rocks.

NASA just picked its newest astronauts—only 0.1% made the cut, with salaries topping $150K and a shot at landing on Mars Forget Ivy League admissions— NASA’s astronaut program has set a sky-high bar for admission standards, and 2025 was no exception.

NASA has found potential signs of life on Mars, the agency said last Wednesday. Although additional scientific study is needed in order to verify the theory, NASA has said the discovery could be the clearest sign of life it has ever found.

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.

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.

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.

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.

Rovers explore distant planets for decades, where humans can't yet go. NASA sends signals from Earth to update the rovers and keep them running.

On Sept. 24, NASA launched a SpaceX Falcon 9 rocket from Cape Canaveral, Fla. carrying three spacecrafts that will examine the effects of the sun on the earth.
