Space Telescope Captures First Glimpse of an Exoplanet’s Interior

James Webb Space Telescope data reveals WASP-107 b has significantly less methane than expected and a surprisingly large core, providing key insights into its atmospheric chemistry and internal dynamics.

A surprisingly low amount of methane and a super-sized core hide within the cotton candy-like planet WASP-107 b.

The revelations, based on data obtained by the James Webb Space Telescope, mark the first measurements of an exoplanet’s core mass and will likely underpin future studies of planetary atmospheres and interiors, a key aspect in the search for habitable worlds beyond our solar system.
