NASA has revealed new images of interstellar comet 3I/ATLAS, which is as large as Manhattan and traveling at speeds of up to 153,000 mph. Discovered on July 1, 2025, it is only the third confirmed interstellar object and exhibits a unique composition, different from solar system comets. The comet will pass closest to Earth on December 19, and scientists are studying its unusual characteristics, which could provide insights into the origins of comets and potentially life on Earth.
