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, ...

Hello, London, it’s ET calling. A group of UK scientists has applied for government funding to open a British listening post in the search for extraterrestrial intelligence (SETI). With annual ...

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: ...

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, ...

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 ...
