Harvard scientist Avi Loeb speculated that NASA’s recently released photos of 3I/ATLAS could potentially point to its artificial origins — and even wondered if the so-called comet was purposely targeting and sweeping meteorites out of its path. He posited his theory in a viral new blog post on Medium.

Scientists from the European Space Agency have significantly narrowed down the trajectory of the interstellar visitor 3I/ATLAS thanks to data from the alien comet's recent flyby of Mars, allowing for more accurate future observations.
