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 ...

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

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.

Turbulent plasma near distant stars could blur ultra-narrow signals before they leave their home star systems - making them ...

Lee said SETI’s paper could answer the Fermi Paradox, the idea that if the universe is billions of years old, where are all ...

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 ...

Solar storms around distant stars may be erasing alien radio signals before we ever hear them In A Nutshell Stellar winds and ...

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

For decades, humanity has been looking for answers to unravel the mystery surrounding aliens’ existence, but they have failed ...
