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 ...

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

Astronomers seeking signs of alien life may have been listening to the wrong spectrums, a new study found. The majority of ...

Astronomers might be hunting for alien signals in all the wrong places. A new ...

Louisa Mason's study uses archived ALMA data to explore new radio frequencies for alien signals, expanding SETI's search ...

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 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 ...

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 ...

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio spectrum that has not recently been explored.

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

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 ...
