New exoplanet L 98-59 d unveils sulfurous magma oceans

Scientists using the James Webb Space Telescope and ground facilities have identified L 98-59 d as a new exoplanet with a sulfur-rich atmosphere and a semi-molten magma-ocean interior, a world that is unusually low in density for its size and unlike previously known rocky or watery planets. The study, published in Nature Astronomy, suggests a broader diversity of planet types and raises questions about other exotic, pungent planets, though the conditions are unlikely to support Earth-like life.
