NEW YORK – Comet 3I/ATLAS’s unusual trajectory and unprecedented size have ignited debates and theories as to what the object could be. A controversial theory put forward by Avi Loeb, a Harvard astrophysicist and his team is that the interstellar object might be some form of “ alien technology .”

The colossal interstellar object was first spotted in Chile by NASA’s ATLAS survey telescope on 1 July, 2025.
