Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU).
A careful study of images taken by the NASA rover Curiosity has revealed intriguing similarities between ancient sedimentary rocks on Mars and structures shaped by microbes on Earth. The findings suggest, but do not prove, ...
Are humans unique and alone in the vast universe? This question—summed up in the famous Drake equation—has for a half-century been one of the most intractable and uncertain in science.
A distant planet known as Kepler-62f could be habitable, a team of astronomers reports.
Earth-like planets around small stars likely have protective magnetic fields, aiding chance for life
Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according to research from astronomers ...
European scientists have gathered tiny fungi that take shelter in Antarctic rocks and sent them to the International Space Station. After 18 months on board in conditions similar to those on Mars, more than 60% of their cells ...
Scientists identify mineral that destroys organic compounds, with implications for Mars Curiosity mission
Scientists have discovered that the mineral jarosite breaks down organic compounds when it is flash-heated, with implications for Mars research.
Astronomers have found a plethora of planets around nearby stars. And it appears that Earth-sized planets in habitable zones are probably common.
As scientists step up their search for other life in the universe, two astrophysicists are proposing a way to make sure we don't miss the signal if extraterrestrial observers try to contact us first.
