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 ...

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

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

The SETI Institute, the nonprofit that conducts a search for extraterrestrial intelligence by examining radio waves for artefacts that are unlikely to be the result of natural processes, thinks it may ...

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 ...

Institute has found that we may have missed transmissions from intelligent alien life for a very benign reason. SETI’s searches are focused only on very narrow signals, so the organization typically ...

A new study by researchers at the SETI Institute suggests stellar "space weather" could make radio signals from ...

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 ...

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