Mars may have been habitable much more recently than thought

Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for ...

Could life at TRAPPIST-1 survive the star's superflares?

The TRAPPIST-1 system is a science-fiction writer's dream. Seven Earth-sized worlds orbit a red dwarf star just 40 light-years away. Three of those worlds are within the habitable zone of the star. The system spans a distance ...

Scientists unveil cosmic fingerprints of sulfur rings

For the first time, a team of scientists from HFML-FELIX at Radboud University has unveiled the cosmic fingerprints of sulfur rings. These results, published in Nature Communications, may shed new light on the way sulfur ...

New research finds lake under Mars ice cap unlikely

Cornell University researchers have provided a simple and comprehensive—if less dramatic—explanation for bright radar reflections initially interpreted as liquid water beneath the ice cap on Mars' south pole.

What impact does ozone have on an exoplanet?

As we discover more and more exoplanets—and the current total is in excess of 5,200—we continue to try to learn more about them. Astrobiologists busy themselves analyzing their atmospheres searching for anything that ...
