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

SETI may have figured out why we haven't detected any alien signals yet, explaining at least part of the infamous Fermi paradox
Researchers from the search for extraterrestrial intelligence (SETI) may have figured out why we have not detected any alien ...
The odds of there being another intelligent life form in the Milky Way are pretty good given the billions of stars. But we ...
K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually ...
We may be missing out on ultra-narrow radio signals sent by technologically advanced civilizations, a new study claims. The study shows that a star’s violent eruptions near an alien planet may distort ...
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 ...
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 ...
With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we ...
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of ...
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.
