TESS Mission Identifies New Exoplanet Using Gravitational Microlensing

NASA's Transiting Exoplanet Survey Satellite (TESS) has successfully detected a new exoplanet, Gaia23bra b, utilizing the gravitational microlensing effect for the first time. This discovery, involving a planet approximately 1.63 times Jupiter's mass orbiting an orange dwarf star, showcases the effectiveness of collaborative space observation. The finding, detailed in the Astrophysical Journal Letters, highlights how combining data from missions like ESA's Gaia and TESS can reveal subtle astronomical phenomena.
