Humans could have come from Mars, scientists have said. A study by Johns Hopkins University has found that alien microbes ...

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

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

Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets ...

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 ...

Scientists reveal one key way we might have missed signals from aliens - ‘Smearing’ of signals could mean that there are ...

What's up with those machines?

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

Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.

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 ...
