Hubble has captured evidence of extraordinary jet activity from the interstellar comet 3I/ATLAS, which challenges established models of cometary physics and raises new questions about the nature of this rare visitor from beyond the Solar System.
Since its discovery on 1 July 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS), the object designated 3I/ATLAS has fascinated astronomers as only the third confirmed interstellar object ever observed. Its hyperbolic trajectory, high speed, and unexpected behaviour have made it an object of intense study and the subject of global scientific scrutiny.
