Super-Earth L98-59 d has a sulfur-rich atmosphere

Astronomers using the James Webb Space Telescope have observed the super-Earth L98-59 d, located 34.6 light years away, revealing a sulfur-rich atmosphere. The planet, 58% larger than Earth and 2.31 times its mass, orbits its star every 7.45 days. Findings indicate high levels of hydrogen sulfide and sulfur dioxide, suggesting active photo-chemistry. The research was published on August 28, 2024.
