Looking for molecular evidence of life on other worlds is tricky, but a test based on the reactivity of carbon compounds ...

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

How far away aliens might detect life on Earth.

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 ...

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

The reason we haven’t heard from aliens could be remarkably simple: interstellar communication is hard, and turbulent plasma ...

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 ...

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

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

Donald Trump has ordered the release of files related to aliens, UAP, and UFOs. If previous disclosures are any indication, get ready for a letdown.

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 ...
