Webb telescope offers first glimpse of an exoplanet's interior | HubA 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.
"Looking into the interior of a planet hundreds of light-years away sounds almost impossible, but when you know the mass, radius, atmospheric composition, and hotness of its interior, you've got all the pieces you need to get an idea of what's inside and how heavy that core is," said lead author David Sing , a Bloomberg Distinguished Professor of Earth and Planetary Sciences at Johns Hopkins University. "This is now something we can do for lots of different gas planets in various systems."
