A new telescope built to to track fast-moving space objects caught a comet from beyond the solar system moving across the sky — before anyone even knew it was there. The NSF-DOE Vera C. Rubin Observatory in Chile recently captured rare footage of the visitor known as 3I/ATLAS — only the third interstellar object discovered.

A newly discovered object in space was spotted about two weeks ago by a telescope in Chile. It's traveling at 135,000 miles per hour, which is too fast to originate from our solar system.

A newly discovered interstellar comet, 3I/ATLAS, has sparked debate in the scientific community after Harvard astrophysicist Avi Loeb and his team proposed a speculative idea-that it might be an alien spacecraft.
