Interstellar comet 3I/ATLAS just cruised by Earth, and scientists couldn’t resist checking if it was an alien probe. Using the Green Bank Telescope, they scanned for any technosignatures—aka, signs of E.T. phoning home. Spoiler: no alien messages, just classic comet vibes. Still, it’s wild to think this icy traveler is older than our Solar System and came from another part of the galaxy! Data’s public if you want to play detective. #Science #3IATLAS #aliens
