The Earth's atmosphere is being littered with new metal aerosols from burning spacecraft and rockets, scientists warn.

Red dwarf stars, the most common type of star in our galaxy, are prime candidates for hosting exoplanets that might support life. These stars are often considered promising targets in the search for ...

We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.

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

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 ...

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

Anyone familiar with the search for alien life will have heard of the "Goldilocks Zone" around a star. This is defined as the orbital band where the temperature is just right for liquid water to pool ...

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 ...
