NASA's TESS Discovers Nearby Earth-Sized Planet in Habitable Zone

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered an Earth-sized exoplanet named Gliese 12 b, located 40 light-years away in the constellation Pisces. Orbiting a red dwarf star, Gliese 12 b lies within the habitable zone, making it a potential candidate for hosting life. The planet's size and proximity to its star suggest it could have a thin atmosphere, similar to Earth's. Further investigations using radial velocity methods and the James Webb Space Telescope aim to determine its atmospheric composition and habitability.
