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 ...
Most SETI attempts have focused on a narrow stretch of the radio spectrum known as the “water hole." ...
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...
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.
Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...
Scientists say the findings of the new study may make future searches for extraterrestrial intelligence faster and more ...
Add Yahoo as a preferred source to see more of our stories on Google. An illustration of an exoplanet in an alien star system. New research suggests that radio emissions from intelligent aliens may be ...
K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced ...
Archived radio observations could open new frequencies to SETI while showing that past searches covered millions more stars ...
A study suggests that stellar plasma may distort alien signals, complicating SETI's search for extraterrestrial life by pushing signals below detection thresholds.
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 ...
