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 ...

Fresh scientific findings highlight two major gaps in the hunt for alien life.

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.

One of the longest-standing techniques in humanity’s search for life beyond Earth may be causing scientists to miss alien signals entirely, a new study finds. Since the very beginnings of the search ...

Staring into the starry night sky convinces many of us that we can’t be alone in this universe. So far, astronomers have been looking for alien signals in a specific part of the radio spectrum, which ...

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.

Researchers found radio telescopes have unknowingly surveyed millions of additional stars, revealing the search for alien ...

Astronomers have been scanning the skies for alien radio signals for decades, but so far they’ve heard nary a peep (with one possible exception). But according to a recent study, that could be because ...

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, ...

Astronomers may have already scanned millions of more stars than they thought, but that might lead to new ways to hunt for ...
