Astronomers Identify L98-59d as a Permanently Molten Exoplanet 35 Light-Years Away

Astronomers have identified L98-59d, a planet about 35 light-years from Earth, notable for its permanently molten surface with temperatures near 1,900°C. Observations from the James Webb Space Telescope reveal it as a new class of exoplanet covered in molten magma, sustained by a strong greenhouse effect and tidal heating from nearby planets. This discovery challenges traditional planet classifications, expanding understanding of planetary evolution under extreme conditions.
