Summary:
- Astronomers have discovered a new "super-Earth" exoplanet called LHS 3844b that orbits a nearby red dwarf star.
- This exoplanet is about 1.3 times the size of Earth and likely has a rocky composition, but it appears to have lost its atmosphere, possibly due to intense radiation from its parent star.
- The lack of an atmosphere on LHS 3844b suggests that some super-Earth planets may not be able to retain their atmospheres, which has implications for the potential habitability of these types of worlds.
