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, ...

Interstellar comet 3I/ATLAS was first spotted in our solar system in July 2025. Since its arrival, scientists have been confident it is a natural comet, but its rare interstellar origin made it an ...

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 ...

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, ...

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the ...

With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more ...

Add Yahoo as a preferred source to see more of our stories on Google. In a series of papers, astronomers have compared the "Wow!" signal to similar radio signals detected at Big Ear Observatory in ...

Are there no alien signals to find... or do we need to update how we search for them? We’ve been looking for messages from the stars ever since Frank Drake pointed the Green Bank radio telescope at ...

NASA’s Pandora mission has begun its hunt for secrets hidden in exoplanet atmospheres. The spacecraft will study at least 20 alien worlds and their host stars, helping scientists separate planetary ...

In 1977, radio astronomers at Ohio State University’s Big Ear telescope in western Ohio picked up a remarkably intense radio signal from deep space. It came from something exceptionally bright and ...
