Radio telescopes have long scanned quiet patches of sky for a lone, artificial-sounding ping, but a growing body of research is pushing astronomers to look instead at the loudest neighborhoods in the ...

Green Bank Telescope rules out alien signals in interstellar comet 3I/ATLAS after rigorous scientific deep search.

Since the first Search for Extraterrestrial Intelligence (SETI) experiment in 1960, scientists have been scanning the Milky Way for signs of advanced alien civilizations. They have looked for unusual ...

A group of Chinese scientists is diving deep into the cosmos in search of alien radio signals from the TRAPPIST-1 star system, which might house planets that could support life. This is no small feat, ...

Alien civilizations could eavesdrop on our communications with our spacecraft and rovers, according to a new study – and we might be able to find them the same way. To tell a Mars rover to turn left ...

Planet K2-18b, an apparent water world 124 light years away, has been seen as a promising location in the search for aliens, ...

Astronomers have detected the first-ever "radio signal" coming from the interstellar comet 3I/ATLAS, right as it passed the halfway mark on its oneway trip through the solar system. And while this may ...

If you've been following exoplanet research over the last couple of years, you've definitely heard of K2-18b. Located 124 ...

A mysterious radio signal has been traced to a galaxy far, far away. And, it's causing a stir among astronomers -- although nobody is sure what it is. Research published this week in the journal ...

For over two decades, millions of people volunteered the computational capacity of their computers to help UC Berkeley scientists in their search for extraterrestrial intelligence (SETI). The goal of ...

Advanced aliens could be chatting with each other using light flashes in plain sight, similar to how fireflies communicate, according to a new study that could lead to new approaches in finding ...

But what if signals did reach Earth and slipped past us? A technosignature is any measurable signal or physical trace that points to the existence of advanced technology beyond Earth, for example, ...
