• Interstellar comet 3I/ATLAS, discovered by the ATLAS survey in Chile, is set to disappear behind the Sun by late September and reappear in December.
• Larger than `Oumuamua and Borisov, 3I/ATLAS offers a unique opportunity to study interstellar objects due to its rare composition and trajectory.
• Spacecraft, including the James Webb Space Telescope (JWST), are tracking 3I/ATLAS as it passes near Mars and Jupiter, providing valuable data.
