The origin of the millisecond-long flashes of radio waves is unknown. Most scientists believe they are generated by powerful astrophysical phenomena such as black holes or superdense neutron stars.

Scientists say the findings of the new study may make future searches for extraterrestrial intelligence faster and more ...

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

Using emerging radio techniques refined during and after the Second World War, the astronomers detected a powerful radio ...

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 ...

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, ...

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 ...

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of ...

A new SETI study argues that turbulent space weather around distant stars can smear out ultra‑narrow alien radio signals, meaning technosignatures may already have reached Earth.

Astronomers suggest that space weather could distort alien signals, making them undetectable. This challenges traditional search methods and highlights the need for broader signal detection strategies ...
