NASA’s Transiting Exoplanet Survey Satellite (TESS) has successfully tracked an interstellar comet identified as 3I/ATLAS, marking a rare and scientifically significant observation of an object originating beyond our solar system. The detection underscores TESS’s growing versatility beyond its primary mission of discovering exoplanets. By capturing the comet’s trajectory and brightness variations, scientists gained valuable insights into its composition and behavior.
