The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

New research suggests that alien radio signals may be transformed by plasma from their home stars — and scientists on Earth could thus be overlooking prime evidence of alien intelligence.

Researchers from the search for extraterrestrial intelligence (SETI) may have figured out why we have not detected any alien ...

Using emerging radio techniques refined during and after the Second World War, the astronomers detected a powerful radio ...

Could the interstellar object 3I/ATLAS exhibit technosignatures, or signals of alien technology? This is what a recent study published in The Astronomical Journal hopes to address as a team of ...

A rare visitor from another star system has undergone one of the most extensive technosignature searches ever conducted on an interstellar object, and the results are now in. According to research ...

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of ...

No alien signals have been detected from an interstellar, cigar-shaped space rock discovered travelling through our Solar System in October, researchers listening for evidence of extraterrestrial ...

A study suggests that stellar plasma may distort alien signals, complicating SETI's search for extraterrestrial life by pushing signals below detection thresholds.

Astronomers suggest that space weather could distort alien signals, making them undetectable. This challenges traditional search methods and highlights the need for broader signal detection strategies ...
