JWST maps the weather on a hot gas giant 700 light-years away

WASP-94A b is a hot, tidally locked gas giant orbiting close to one of the stars in a binary system roughly 690 light-years away from Earth. In a new Science study, scientists led by Sagnick Mukherjee, an astrophysicist at Johns Hopkins University, used the James Webb Space Telescope to learn what the weather looks like out there. Tidal locking means that you no longer have day- and night-side temperature differences sweeping across the planet.
