JWST reveals a strange sulfur world unlike any planet we know

JWST Discovers Sulfur-Rich Exoplanet That Defies Classification

JWST found unusual sulfur-rich atmospheric chemistry on exoplanet L 98-59 d, 35 light-years away
The planet likely contains a deep magma ocean that traps sulfur compounds under extreme pressure, lowering its detectable density
The discovery suggests sulfur worlds may be a common but previously unrecognized class of planet

Hidden Water Reservoir Found Deep Beneath Mars Surface

InSight seismic data suggests a liquid water reservoir exists 10-20 km beneath Mars's surface in water-saturated fractured rock
Discovery may explain where Mars's ancient surface water went and reopens questions about deep-crust habitability
Water is far too deep for any near-term drilling technology; confirmation awaits future missions
