Briefing: A new class of molten planet stores abundant sulfur in a perpetual magma ocean

A recent study from the University of Oxford has uncovered a new type of exoplanet that features a permanent ocean of magma, which contains substantial amounts of sulfur.

This discovery has implications for our understanding of planetary formation and the chemical composition of celestial bodies beyond our solar system.

The findings were published in the journal Nature Astronomy on March 16, 2026, highlighting the potential for further exploration of sulfur's role in planetary geology.
