Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...
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." ...
Louisa Mason's study uses archived ALMA data to explore new radio frequencies for alien signals, expanding SETI's search ...
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...
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.

Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that ...
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 ...
Experts stress need for transparency while aiming to prevent premature announcements and protect scientists ...
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 ...
