Scientists say the findings of the new study may make future searches for extraterrestrial intelligence faster and more effective.
Most SETI attempts have focused on a narrow stretch of the radio spectrum known as the “water hole." ...
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 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 ...
If advanced aliens lived on a planet within a few hundred to a thousand light years away from Earth, then vast numbers of their signals must already have crossed Earth without being noticed, a new ...
What steps can be taken to identify why we haven’t received radio signals from an extraterrestrial intelligence, also called technosignatures? This is what a recent study published in The ...
Experts stress need for transparency while aiming to prevent premature announcements and protect scientists ...
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...
The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...
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 ...
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 ...
