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 ...

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 ...

Researchers have announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia. The research is the first to search for signs of alien technology in galaxies beyond ...

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 ...

Given the vast size of the universe, many astronomers believe that it is almost certain that humanity is not the only advanced civilisation living amongst the stars. However, this leaves one very ...

The SETI Institute, the Berkeley SETI Research Center and the International Centre for Radio Astronomy Research announced a study using the Murchison Widefield Array (MWA) in Western Australia. Led by ...

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, ...
