The interstellar comet 3I/ATLAS (C/2025 N1), discovered on July 1, 2025, by the ATLAS survey telescope in Chile, is the third confirmed interstellar object to enter our solar system. Recent observations, including the sharpest images captured by NASA's Hubble Space Telescope, reveal that 3I/ATLAS is traveling at approximately 130,000 miles per hour (209,215 km/h or 58 km/s). The comet exhibits a compact coma and a vivid tail, indicating an icy core with a size estimated between 320 meters and 5.6 kilometers, which is smaller than initially thought. Analysis suggests that 3I/ATLAS resembles comets originating from the outer reaches of our solar system. Ground-based telescopes are expected to continue observing the comet until September, after which it will become obscured by solar glare. NASA has clarified that 3I/ATLAS is not an extraterrestrial spacecraft but a natural comet with an icy nucleus and coma. The detailed imagery and data from Hubble and other observatories provide new insights into the comet's origin and composition as it travels through the solar system.
