Summary:

- The James Webb Space Telescope has observed a rocky exoplanet, GJ 1252 b, that is being vaporized by its host star's intense radiation.
- GJ 1252 b is an ultra-hot, rocky exoplanet that orbits extremely close to its M-dwarf host star, with an orbital period of just 12 hours.
- The observations from JWST suggest that the planet's surface may be partially or completely molten, with the intense stellar radiation stripping away the planet's atmosphere and causing the rocky material to be vaporized.
