Story summary
- The James Webb Space Telescope mapped the climates of TRAPPIST-1b and TRAPPIST-1c, two rocky exoplanets 38.8 light-years away.
- They exhibit extreme temperature differences: daytime highs above 200°C and nighttime lows below -200°C, indicating a lack of atmosphere.
- The study attributes atmospheric loss to intense radiation from the host red dwarf star.
- The findings, published in Nature Astronomy, note that the outer TRAPPIST-1 planets may have atmospheric conditions conducive to life.
