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 ...

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

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

Scientists believe turbulent “space weather” around distant stars could be scrambling potential alien signals before they ...

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

Scientists believe the most likely first contact will come through faint radio signals, not spacecraft, as we listen for ...

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

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 ...

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

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.

A new study by the SETI Institute suggests that the alien signals might be right here, surrounding us all of the time, and we're just unable to pick them out.
