Have we been missing radio communication signals from intelligent alien civilisations because we've been listening in on the wrong frequency? A group of astronomers say that could very well be the ...

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

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 ...

When/if alien life ever cruises toward Earth in big spaceships, we’re probably not just going to see it; we’re going to hear it via narrow radio signals. If an extraterrestrial civilization wanted to ...
