L98-59d: A First-of-Its-Kind Exoplanet with a Global Magma Ocean and a Hydrogen-Sulfide Atmosphere
To the point
Scientists have identified L98-59d, a brand-new type of planet about 35 light-years away around a small red star, roughly 60% larger in diameter yet only 40% as dense as Earth, likely a fully molten world with a magma ocean and a 900 C surface, an atmosphere rich in hydrogen sulfide that would smell like rotten eggs, making life as we know it unlikely, with Dr. Harrison Nicholls of Oxford noting no crust or mantle and a molten core, illustrating the surprising variety of planets beyond our solar system.
