Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has focused on for decades. Reading time 3 minutes For over half a century, the ...

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 ...

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 ...

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and ...

・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 ...

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, ...
