New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder ...

A provocative theory circulating among artificial intelligence researchers suggests that once machines achieve human-level intelligence and beyond, they might create something entirely unexpected: a ...

Add Yahoo as a preferred source to see more of our stories on Google. For decades, humanity has scoured the cosmos for any signs that we aren't alone in the universe. But now, researchers at the SETI ...

For decades, the search for alien intelligence has revolved around the question: if someone out there is listening, how could they hear us? A new study combining data from Penn State and NASA’s Jet ...

SETI has spent decades listening for a sharp, well-defined radio signal that could indicate it was sent by distant intelligent life. Now researchers believe that space weather could distort and blur s ...

A new study suggests a novel approach in the long-running scientific endeavor to find intelligent life beyond Earth. Instead of casting a wide, speculative net across the cosmos, researchers from Penn ...

Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?

Advanced alien civilizations may communicate via a series of flashing lights, similar to how fireflies do, a new paper hints. This would potentially make extraterrestrials much harder to spot if we ...
