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.

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 ...

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

Researchers from the search for extraterrestrial intelligence (SETI) may have figured out why we have not detected any alien signals as of yet, and it could partly explain the infamous "Fermi paradox" ...

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 ...

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 ...

A new SETI study argues that turbulent space weather around distant stars can smear out ultra‑narrow alien radio signals, meaning technosignatures may already have reached Earth.
