They’ve got their 3Is on the prize. The highly anticipated data 3I/ATLAS’ Earth tour last month is in. A targeted scan of ...

A dedicated scan for signs of radio-transmitting technology in interstellar comet 3I/ATLAS has come back with absolute ...

Across the observable universe, galaxies advertise themselves in radio waves for familiar reasons-magnetic fields, cosmic ...

Scientists scanned interstellar Comet 3I/ATLAS for alien signals using powerful radio telescopes, found nothing artificial, ...

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 ...

The latest hunt for alien signals in the TRAPPIST-1 planetary system has test-driven a new strategy that will allow astronomers to perform a more efficient, targeted search for technological ...

The Search for Extraterrestrial Intelligence (SETI) focuses on finding technosignatures—potential signs of alien technology. If we look carefully, we might have a chance at detecting their ...

A new SETI methodology focuses on detecting the "spillover" from directed interstellar communications, mirroring how we communicate with our own spacecraft, rather than relying on broad, speculative ...

The Deep Space Network (DSN) is just the sort of tool aliens could one-day detect, transmitting from Earth. Credit: NASA/JPL What if the first signal ever detected from an alien lifeform wasn't a ...
