JWST Maps TRAPPIST-1b and 1c as Bare Rocky Worlds With Extreme Day-Night Contrasts
Key Takeaways
- Webb observed TRAPPIST-1b and 1c continuously for 60 hours in infrared light.
- Researchers created the first temperature maps of Earth-sized exoplanets around another star.
- Both planets show extreme day-night temperature differences, implying little or no atmosphere.
- The result helps clarify what kinds of red-dwarf planets may be able to retain atmospheres.
