“The universe is not as quiet as we were told.” The line belongs to a dramatic retelling of a disputed signal claim, but it captures a sober scientific problem: the first technosignature humanity ...

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

Scientists hunting for extraterrestrial life believe alien civilisations may indeed be attempting to contact Earth, but ...

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

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

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

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

Scientists reveal one key way we might have missed signals from aliens - ‘Smearing’ of signals could mean that there are ...

If advanced aliens lived on a planet within a few hundred to a thousand light years away from Earth, then vast numbers of their signals must already have crossed Earth without being noticed, a new ...

A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma ...
