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, ...

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 ...

For years, astronomers looking for intelligent extraterrestrial civilizations have scanned the skies for a small part of the radio spectrum. To date, they haven’t heard anything. To expand the ...

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 ...

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: ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study has found that stellar "space weather" could be making it significantly harder to detect potential signals from aliens ...

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 ...

A comet from another star system does not arrive every year. That is part of what made 3I/ATLAS so compelling when it appeared in July 2025. It streaked into the Solar System on a path so extreme that ...

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, ...

No alien signals have been detected from an interstellar, cigar-shaped space rock discovered travelling through our Solar System in October, researchers listening for evidence of extraterrestrial ...
