Humans have been searching the stars for alien radio signals for decades — and so far, E.T. has not phoned home. But that doesn’t mean intelligent life isn’t out there, a new study hints. Rather, ...

Given the size and age of the universe, it should be full of species with technology far more advanced than our own. But so far there is no trace ...

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, ...

Could the interstellar object 3I/ATLAS exhibit technosignatures, or signals of alien technology? This is what a recent study published in The Astronomical Journal hopes to address as a team of ...

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 ...

Scientists around the world have spent decades pointing radio telescopes at the sky, hoping to catch that one signal proving we’re not alone in the universe. But now researchers at SETI are asking: ...
