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 ...

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 ...

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

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

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

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

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

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

They had larger heads, larger eyes,” she said, describing one alien group. At the 24th annual Conscious Life Expo, which ...

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

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