The Search for Extraterrestrial Intelligence (SETI) has a data scale problem. There are just too many places to look for an interstellar signal, and even if you're looking in the right place you could ...

The SETI Institute is the latest to confirm what scientists have long suspected: the interstellar 3I/ATLAS comet is not an alien spaceship.

For decades, scientists have scanned the stars for even the faintest whisper of intelligent life. Now, with fresh government revelations about mysterious skies stirring up fresh excitement, a major ...

Solar winds and coronal mass ejections may scatter narrow signals, making them harder for Earth-based telescopes to detect. The SETI Institute uses radio telescopes to search for signs of intelligent ...

The recent, widely covered signal that's allegedly got SETI hot and bothered is almost certainly not aliens. But that doesn't mean it's not cool. Share on Facebook (opens in a new window) Share on X ...
