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

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 ...

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

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these ...

Do aliens exist? Few debates have proved as enduring – or as divisive – as the question of whether there is life beyond Earth.

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.

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 ...

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 ...
