Webb Telescope Unveils Secrets of Mysterious Puffy Exoplanet

The James Webb Space Telescope has provided a detailed look at the exoplanet WASP-107b, revealing that its low methane atmosphere and high internal temperature explain its unusually low density. This new data suggests that WASP-107b has a much larger core than previously thought, aligning with existing planetary formation models and negating the need for radical revisions. The findings indicate that the planet's elliptical orbit and resulting gravitational stress likely contribute to its internal heat.
