For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the ...

New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder ...

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

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 ...

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

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

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

Scientists hunting for extraterrestrial life believe alien civilisations may indeed be attempting to contact Earth, but ...

We might have missed signals from aliens because they are being disrupted by the conditions of space, scientists have warned.

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