MARS

An earthquake with a magnitude of 7.4 struck off the southern coasts of Chile and Argentina on Friday, prompting the evacuation of the Chilean coastline throughout the Magallanes region and the suspension of water activities and...
Geologists led by the University of Maryland and the University of Hawaiʻi finally connected the dots between one of the largest volcanic eruptions in Earth's history and its source deep beneath the Pacific Ocean. In a paper published in...

A step towards life on Mars? Lichens survive Martian simulation in new study

For the first time, researchers have demonstrated that certain lichen species can survive Mars-like conditions, including exposure to ionizing radiation, while maintaining a metabolically...

Shocking spherules on Mars

Last week, the Perseverance Science Team were astonished by a strange rock comprised of hundreds of millimeter-sized spheres… and the team are now working...

Organic molecules of unprecedented size discovered on Mars

The longest organic molecules identified to date on Mars have recently been detected by scientists from the CNRS, together with their colleagues from France,...

Weighing in on a Mars water debate: Analysis challenges previous findings

More than 3 billion years ago, Mars intermittently had liquid water on its surface. After the planet lost much of its atmosphere, however, surface...
