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

Researchers who listen for signs of non-human life say signals ‘can slip below detection thresholds, even if it’s there’ ...

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.

A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma ...

E.T. could be phoning home — but we’re not hearing the call. A new study published in The Astrophysical Journal argues that “space weather” could be distorting incoming transmissions from ...

Solar storms around distant stars may be erasing alien radio signals before we ever hear them In A Nutshell Stellar winds and ...

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 ...

For decades, humanity has been looking for answers to unravel the mystery surrounding aliens’ existence, but they have failed ...

Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?

The Fermi Paradox asks a simple but unsettling question: if the universe is so vast, why haven’t we found evidence of alien civilizations? Scientists have proposed many explanations, but some of the ...
