NASA's telescopes have captured detailed observations of interstellar object 3I/ATLAS, confirming it as a natural comet rich in CO₂ and water ice. Discovered in 2025, the comet's composition and trajectory align with known processes of icy comets ejected from other star systems, debunking speculation about alien origins. Ongoing observations aim to understand its structure and activity.

NASA has shared new details about 3I/ATLAS. It is an interstellar object moving at 209,000 km/h. Hubble images show it is smaller than thought, about 5.6 km wide. It is a comet with a glowing tail. Scientists estimate it is eight billion years old. It poses no threat to Earth. NASA uses telescopes to study it.
