Summary
NASA researchers using the James Webb Space Telescope are investigating the origins of interstellar comet 3I/ATLAS, discovered on July 1, 2025 by the ATLAS system. JWST observations have revealed unusual ratios of carbon and heavy hydrogen in the comet that differ from comets found in our solar system, providing clues about its interstellar origins. 3I/ATLAS is only the third interstellar object ever discovered.
