Could exoplanets locked in eternal day and endless night support life?

Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The result? One side of LHS 3844b is perpetually bathed in scorching sunlight, locked into a never-ending,...

Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The result? One side of LHS 3844b is perpetually bathed in scorching sunlight, locked into a never-ending, blistering hot day, while the other is forever shrouded in darkness so cold that particles are incapable of movement, a state known as absolute zero (zero Kelvin).
