ASU professor Davies addresses why we have yet to find extraterrestrial life

Fri, 16 Feb 18 00:01:50 -0800

Are we alone in the universe? Few questions have captured the public imagination more than this. Yet to date we know of just one sample of life, that which exists here on Earth. Arizona State University Regents Professor and noted cosmologist Paul Davies will talk about efforts to identify extraterrestrial life at a press briefing Feb. 16 at the annual meeting of the American Association for the Advancement of Science in Austin, Texas.

Soft tissue fossil clues could help search for ancient life on Earth and other planets

Thu, 15 Feb 18 00:11:50 -0800

Fossils that preserve entire organisms (including both hard and soft body parts) are critical to our understanding of evolution and ancient life on Earth. However, these exceptional deposits are extremely rare. New Oxford University research suggests that the mineralogy of the surrounding earth is key to conserving soft parts of organisms, and finding more exceptional fossils. Part-funded by NASA, the work could potentially support the Mars Rover Curiosity in its sample analysis, and speed up the search for traces of life on other planets.

Mars: Not as dry as it seems

Wed, 20 Dec 17 00:02:40 -0800

Two new Oxford University papers have shed light on why there is no life on Mars. Although today's Martian surface is barren, frozen and inhabitable, a trail of evidence points to a once warmer, wetter planet, where water flowed freely -- and life may have thrived. The conundrum of what happened to this water is long standing and unsolved. However, new research published in Nature suggests that this water is now locked in the Martian rocks.

A model of Mars-like protoplanets shed light on early solar activity

Thu, 14 Dec 17 00:12:50 -0800
