Researchers found radio telescopes have unknowingly surveyed millions of additional stars, revealing the search for alien civilisations has been broader than scientists realised.

Astronomers may have already scanned millions of more stars than they thought, a realization that might lead to new ways to hunt for extraterrestrial radio signals.

Astronomers searching for extraterrestrial intelligence have traditionally focused on a specific, narrow band of the radio ...

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 ...

Researchers are using ALMA data to search radio bands that have been largely unexplored for alien signals.

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 radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 GHz.

SETI’s search for extraterrestrial signals reached 21 times more stars than any prior published survey had claimed, according ...

What you'll discover in this article ・The Search for Extraterrestrial Intelligence has mostly focused on a narrow range of ...

Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has ...

A new study by PhD researcher Louisa Mason (UoM) suggests astronomers may be missing potential alien signals by focusing too ...
