Astronomers at South Africa's MeerKAT radio telescope have detected the first radio waves coming from the interstellar comet ...

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 ...

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 ...

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 first unmistakable signal from another intelligence would rank alongside fire and writing in the story of our species, yet a growing group of researchers warns that such a moment might arrive not ...

It's difficult to believe that, given the enormous extent of outer space around us, there aren't other life forms out there. Humanity has long been intrigued by the idea, with movies, books, and TV ...

Louisa Mason's study uses archived ALMA data to explore new radio frequencies for alien signals, expanding SETI's search beyond traditional methods and increasing the number of stars surveyed.

The search for alien radio signals has spent decades listening in a familiar part of the spectrum. A first-of-its-kind survey now suggests that unexplored higher frequencies could widen the hunt, ...
