Washington: In its first, astronomers using James Webb Telescope have discovered an Exoplanet nor previously known, American space agency NASA said. The new exoplanet is of mass similar to Saturn and orbiting the young nearby star TWA 7. Since its launch in 2021, JWS Telescope has sent important data on various already-known exoplanets. The international team detected a faint infrared source in the disk of debris surrounding TWA 7 using Webb’s MIRI (Mid-Infrared Instrument).
