Most alien-signal searches listen to a narrow part of the radio spectrum, but astronomers are now testing higher frequencies that have barely been explored. A first search using archived ALMA ...
Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...
Most SETI attempts have focused on a narrow stretch of the radio spectrum known as the “water hole." ...
Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ...

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!
Most radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 GHz.
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 ...
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...
A study suggests that stellar plasma may distort alien signals, complicating SETI's search for extraterrestrial life by pushing signals below detection thresholds.
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 ...
