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

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

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 ...

Donald Trump has ordered the release of files related to aliens, UAP, and UFOs. If previous disclosures are any indication, get ready for a letdown.

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

The reason we haven’t heard from aliens could be remarkably simple: interstellar communication is hard, and turbulent plasma ...

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

E.T. could be phoning home — but we’re not hearing the call. A new study published in The Astrophysical Journal argues that “space weather” could be distorting incoming transmissions from ...

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

A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma ...
