Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new ...

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

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

Scientists demonstrated that an Earthly extremophile might withstand being ejected from the Red Planet on debris spewed into ...

Red dwarf stars, the most common type of star in our galaxy, are prime candidates for hosting exoplanets that might support ...

Scientists tested whether microbes can survive the shock of a planetary impact and found some may endure the violent launch into space.

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

Our solar system hosts almost 900 known moons; more than 400 orbit the eight planets while the remaining orbit dwarf planets, ...

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

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

For life to develop on a planet, two chemical elements are needed in sufficient quantities: phosphorus and nitrogen. Phosphorus is vital for the formation of DNA and RNA. Nitrogen is an essential ...
