A study by alien searchers at the SETI Institute (Search for Extraterrestrial Intelligence) could explain why humanity has ...

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.

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 ...

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

Green Bank Telescope rules out alien signals in interstellar comet 3I/ATLAS after rigorous scientific deep search.

What if there were aliens on some distant planet and what if they tried to contact us, but we were not able to pick up the message? That is the question that has been raised by a group of scientists.

If it were a phone call, we might call it a butt dial: A strong radio signal that set off questions about whether it emanated from an advanced alien race earlier this week is now believed to have come ...

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 ...

For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what ...
