Hubble Telescope captured the clearest image yet of interstellar comet 3I/ATLAS, traveling at 130,000 mph. The comet's dust cocoon is visible in the image, while its nucleus size is estimated between 3.5 miles and 1,000 feet in diameter. Scientists are using multiple telescopes, including James Webb, to study its composition. 3I/ATLAS is only the third interstellar object observed in our solar system, offering insights into its age and origin, which are still largely unknown. The Vera Rubin Observatory is expected to discover more such objects in the coming years.
