James Webb’s Giant Mercury: The Airless Super-Earth With an 11-Hour Year

LHS 3844 b is a scorching rocky super-Earth orbiting its red dwarf star in only eleven hours. Using Webb’s mid-infrared instruments, astronomers found evidence for a dark, nearly airless surface that may resemble basalt or mantle-like rock. This distant world is not a literal copy of Mercury, but its exposed stone offers a rare opportunity to study how rocky planets lose atmospheres, weather under stellar radiation, and preserve clues about their geological history. In this quiet science documentary, the surface of an unseen planet becomes a readable archive of heat, minerals, and time.
