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 ...

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

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 ...

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 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 that stellar "space weather" could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma ...

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

A recent study by EPFL finds that extraterrestrial signals in the Milky Way are likely rare and distant, with few detectable transmissions reaching Earth at any time ...

Narrowband signal detection as a potential indicator of artificial radio emissions. Doppler drift correction to account for relative motion between Earth and distant transmitters. Rigorous filtering ...
