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

Tests conducted with tardigrades suggest that there is something in Martian dirt that dramatically reduces biological ...

"Life might actually survive being ejected from one planet and moving to another." ...

A storm from the Sun can make a planet’s sky glow or a spacecraft’s computer stumble. At Mars in May 2024, it did both, just without the auroras people photographed on Earth.

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 ...

A new study shows how simulated Mars dust affects tardigrades, offering insight into space farming and contamination risks.

When the surface of the Sun exploded with activity in May 2024, Earth was hit by the biggest solar storm in more than two ...

Learn how bacteria survived a simulated asteroid impact and could travel between planets on asteroid debris.

Why it matters: While not evidence of life, these discoveries show that ancient Mars had complex organic chemistry, ...

What happens when a solar superstorm hits Mars? Thanks to the European Space Agency's Mars orbiters, we now know: glitching ...

Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.

On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab. Everything is wired together so well that you rarely think about the ...
