Life's capacity to survive in simulated lunar and Martian soils has been explored in two papers published in Scientific ...

Reserachers gathered experimental data exploring whether bacteria could survive a journey between planets via an asteroid ...

A new study challenges the traditional boundaries of the habitable zone, showing that liquid water could exist on the dark ...

Looking for molecular evidence of life on other worlds is tricky, but a test based on the reactivity of carbon compounds ...

A new study has provided compelling evidence that life from Mars could have arrived on Earth by hitching a ride on debris ejected during asteroid impacts. The research, led by scientists at Johns ...

Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

Beyond that, in the decades to come, we might be able to see the colours of an exoplanet’s surface, and determine if plant life might be present there. And then we can search for changes in a planet’s ...

Life needs nutrients like nitrogen and phosphorus. But without the right balance of oxygen, these elements get locked away in planets’ cores.

Hardy bacteria in a lab survived pressures comparable to an asteroid strike on the red planet, suggesting a hypothetical scenario in which our planet was seeded with life.

Our search for extraterrestrial life has turned up empty, perhaps because technologically advanced civilizations are doomed ...

Scientists identify exoplanet candidate HD 137010 b, a possible Earth-size world orbiting a Sun-like star 146 light-years away ...

Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of ...
