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

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 ...

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 ...

SETI researchers may have missed alien signals due to a cosmic phenomenon that distorts narrowband radio waves, new research says.

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

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

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

Stellar activity and plasma turbulence could distort narrow radio signals before they leave their home planetary systems, potentially explaining part of the long silence in the search for ...

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