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

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 ...

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

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 new study suggests.

A study by alien searchers at the SETI Institute (Search for Extraterrestrial Intelligence) could explain why humanity has ...

Turbulent plasma near distant stars could blur ultra-narrow signals before they leave their home star systems - making them difficult to detect.

Scientists have long predicted that as long as there are countless stars like the Sun in the universe, intelligent life should exist on other planets, just as it does on Earth. However, for decades, n ...

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