There's a planet out there called LHS 3844 b, orbiting a star about 48 light-years away. The Transiting Exoplanet Survey Satellite (TESS) found it in 2018 when the planet transited across the face of its star. The James Webb Space Telescope zxeroed in on the planet and found it to be a barren, rocky place with no atmosphere.
