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 ...

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 ...

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

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 ...

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

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

According to a new study, any alien civilizations out there? Probably short-lived — and doomed to fail spectacularly. For ...

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 solar storms around distant stars may be distorting alien radio signals ...

Astronomers used the VLA and MeerKAT radio telescopes to search the Hycean exoplanet K2-18b for alien technosignatures, analyzing millions of signals but finding no confirmed artificial radio transmis ...

The planet K2-18b, which drew intense speculation last year due to apparent signs of life, shows no signs of advanced civilisation after a comprehensive search for radio signals from it. In 2025, ...
