Nearby super-Earth LHS 3844 b is a rocky world orbiting a red dwarf star, only 48.5 light-years away. Its surface is scorched and featureless, with temperatures exceeding 725°C. Unlike Earth, this planet lacks atmosphere, making it extremely hot and airless. However, its composition suggests it may resemble Mercury or the moon in appearance—dark and basaltic. The James Webb Space Telescope (JWST) observed this world, revealing that its crust likely consists of basalt, unlike Earth’s silicate structure. Scientists believe this planet could support life if we could overcome extreme heat, though current data points toward long-term geological activity. While not Earth-like, LHS 3844 b offers insights into planetary formation and habitability. As the researchers noted, such worlds might have similar characteristics to terrestrial planets, raising questions about their potential for supporting life despite harsh conditions.
