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 ...

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

Lee said SETI’s paper could answer the Fermi Paradox, the idea that if the universe is billions of years old, where are all ...

Recent media coverage highlights the wide range of research, education, and scientific perspectives emerging from the SETI ...

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

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

New research suggests that stormy space weather could be interfering with potential messages from extraterrestrial life, ...

The reason we haven’t heard from aliens could be remarkably simple: interstellar communication is hard, and turbulent plasma emitted by stars makes it harder. A new study proposes that when listening ...

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

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 ...
