The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.

For over six decades, the Search for Extraterrestrial Intelligence (SETI) has been tirelessly scanning the cosmos for signs ...

SETI has spent decades listening for a sharp, well-defined radio signal that could indicate it was sent by distant intelligent life. Now researchers believe that space weather could distort and blur s ...

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

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

We might have missed signals from aliens because they are being disrupted by the conditions of space, scientists have warned. Messages being sent from distant planets could be disrupted by activity ...

According to a new study, any alien civilizations out there? Probably short-lived — and doomed to fail spectacularly. For ...
