No alien signals found from interstellar comet 3I/ATLAS
Scientists just finished a worldwide search for signs of alien technology coming from 3I/ATLAS, an interstellar object—likely a comet—that zipped into our solar system earlier this year.
Using some of the world's most powerful telescopes, they listened closely for anything unusual—but found only natural signals.
So, for now, 3I/ATLAS looks like just another visitor from deep space.
How did they look for signs of life?
The Breakthrough Listen team kicked off their hunt right after the interstellar object 3I/ATLAS was discovered earlier this year.
The Allen Telescope Array scanned a huge range of radio frequencies and logged a large number of candidate signals—though none turned out to be artificial.
Later, the Green Bank and MeerKAT telescopes joined in, confirming that all detected signals came from Earth or were typical comet emissions.
Bottom line: no evidence of aliens this time, but every scan helps us learn more about what's out there.
