TESS Mission's First Earth-size World in Star's Habitable-zone

The video discusses the discovery and study of the TOI 700 system, focusing on the planet TOI 700D, which is in the habitable zone and may have liquid water. TESS observed transits to identify planets, and Spitzer confirmed TOI 700D's existence. The planets vary in size and composition, with TOI 700D being Earth-sized and potentially rocky. Future research aims to measure their masses and explore atmospheric conditions. Models suggest diverse environments, aiding predictions for future observations.
