Researchers are exploring the exoplanet LHS 3844b, which is slightly larger than Earth and orbits a red dwarf star, located 48.5 light-years from our solar system. This tidally locked planet has one side in perpetual sunlight while the other remains in constant darkness, and scientists suggest that heat within it could circulate in a stable loop, making it potentially more hospitable to life than previously believed. Using a laboratory model, the study aims to better understand the extreme surface conditions of such exoplanets and their implications for supporting life.
