Watch: Nasa releases new images of interstellar comet 3I/ATLAS

NASA has unveiled new images of comet 3I/ATLAS, indicating it originated from the Milky Way's thin or thick disk layer. Discovered in July 2025 by the NASA-funded Atlas survey telescope in Chile, the comet was observed during solar conjunction on 21 October 2025. Scientists suggested that if 3I/ATLAS came from the thick disk, it could be over seven billion years old, surpassing the age of the solar system.
