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 ...

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

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

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

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

For over six decades, the Search for Extraterrestrial Intelligence (SETI) has been tirelessly scanning the cosmos for signs of alien life. Despite its extensive efforts, the universe remains eerily ...

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

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

For decades, humanity has been looking for answers to unravel the mystery surrounding aliens’ existence, but they have failed ...

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

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 extraterrestrial intelligence harder to detect. Stellar activity and plasma ...
