The hunt for intelligent life beyond Earth has quietly entered a more exacting phase, and one small, cool star has become a ...

Researchers used Green Bank Telescope to detect radio signals from 3I/ATLAS just before its closest approach to Earth.

Aliens might be transmitting communications signals to each other across exoplanets, some astronomers think. Since these signals are likely sent as narrowband radio waves, we may now have a way to ...

A challenge facing alien hunters is discerning natural from artificial signals, but new research suggests we're better equipped than we thought. Reading time 3 minutes An encouraging new study has ...

Scientists have sought out and detected radio emissions from from interstellar comet 3I/ATLAS, all but confirming that it has natural origins.

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...

Visitation from an alien intelligence would be either the coolest or the worst thing that could happen to our species. From the moment an alien showed up on our radar, we’d be in for a world of ...

In 2007, David Narkevic, then a physics undergrad student at West Virginia University, stumbled on something unusual when combing through archival data. Two of his professors, Duncan Lorimer and Maura ...

If aliens are synchronizing their signals with light coming from supernova 1987A, then the search for extraterrestrial intelligence (SETI) is on the case. Scientists with the institution say they may ...

That’s the question at the center of Pop Mech ’s new story, “ Aliens Probably Exist—But They’re Staying Silent For a Reason, ...

A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen ...
