LHS 3844 b, informally named Kua'kua, is a super-Earth located approximately 48 light-years from Earth. Discovered by the Transiting Exoplanet Survey Satellite (TESS) in 2018, Kua'kua is about 30% larger than Earth and orbits its red dwarf star Batsu every 11 hours. The James Webb Space Telescope (JWST) recently analyzed Kua'kua using its Mid Infrared Instrument (MIRI), revealing a barren, rocky surface devoid of an atmosphere. Researchers led by Sebastian Zieba from Harvard's Center for Astrophysics found that the planet's surface likely consists of dark, volcanic rock rather than Earth-like silicate crusts, indicating limited geological activity and minimal water presence. The study suggests that Kua'kua may resemble Mercury in surface characteristics but is significantly hotter. Ongoing observations with JWST aim to further clarify the planet's geological history and surface conditions, potentially providing insights applicable to other rocky exoplanets.
