Astronomers using NASA's TESS space telescope have discovered a super-Earth exoplanet called TOI-1080 b orbiting a red dwarf star 83 light-years away. The rocky planet is about 1.2 times Earth's radius with 1.75 Earth masses, completing an orbit in just under four days. The planet sits within the habitable zone with an equilibrium temperature of 368 K, suggesting it could potentially harbor a carbon dioxide or oxygen-rich atmosphere.
