Is interstellar object 3I/ATLAS an alien spacecraft? Debate intensifies

Technology Nov 15, 2025

The mysterious interstellar object 3I/ATLAS is set to swing by Earth in December 2025, and it's generating significant interest among scientists.
While most experts say it's just a comet made of carbon dioxide ice, Harvard's Avi Loeb thinks there might be more to the story—he suggests it could even be a piece of alien technology, pointing to unusual features seen in telescope images.

Scientists weigh in as flyby approaches

Not everyone is convinced by the alien theory. Astronomers like Jason Wright from Penn State point out that similar comet "anti-tails" have been spotted before and have natural explanations.
Still, Loeb encourages keeping an open mind as we get ready for this rare close encounter—who knows what new details we'll uncover when 3I/ATLAS passes by?
