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 ...

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 hunting alien signals say turbulent stellar plasma around distant worlds may be scrambling extraterrestrial transmissions before they ever reach Earth, according to a new study published ...

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio ...

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more natural source. In a series of papers, astronomers have compared the "Wow!

For more than six decades, astronomers have listened for possible signals from extraterrestrial civilisations, with no confirmed detection to date. A new statistical study considers a narrower and ...

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

Astronomers recently carried out a radio scan of the interstellar object known as 3I/ATLAS as it passed near Earth. The object, which originated outside the solar system, has drawn attention since its ...

Seventy-five years ago, a group of Dutch astronomers made a remarkable discovery. Using emerging radio techniques refined during and after the Second World War, the astronomers detected a powerful ...
