## Resource

Using infrared observations from the James Webb Space Telescope, astronomers have inferred the surface composition of LHS 3844 b.The planet appears to be a hot, airless super-Earth with a dark, basaltic surface and no signs of Earth-like tectonics, likely covered in radiation-processed dust. The result marks a shift from studying exoplanet atmospheres to directly probing their geology. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
