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

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more natural source. In a series of papers, astronomers have compared the "Wow!

On August 15, 1977, the Big Ear Radio Telescope in Delaware, Ohio, received the most powerful signal it would ever detect during its decades of observations. The signal lasted just 72 seconds, but ...

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 ...

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...
