SETI Expands the Search for Alien Signals — Have We Been Listening to the Wrong Radio Channel?
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 seemed the most likely frequency other intelligent life forms would want to communicate through. Moreover, changing the strategy has also helped scientists better understand where they’ve already looked for signals and where to focus next."For decades, SETI searches have concentrated on a relatively small part of the radio spectrum.

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 seemed the most likely frequency other intelligent life forms would want to communicate through. But now they’re wondering: Have we not heard from aliens yet because we were listening to the wrong channel all along?A new study led by a researcher from the University of Manchester and presented at the Royal Astronomical Society's National Astronomy Meeting before being published as a paper proposes expanding the search to higher radio frequencies for technological signals (radio signals that are unlikely to occur naturally and may instead indicate advanced technology) from non-human…
