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 ...

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

Scientists hunting for extraterrestrial life believe alien civilisations may indeed be attempting to contact Earth, but ...

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

Stellar activity and plasma turbulence could distort narrow radio signals before they leave their home planetary systems, potentially explaining part of the long silence in the search for ...

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

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