The shape of WASP-17b’s atmosphere mapped using transmission strings. The planet has a broad banded jet around the equator with vast wind speeds which transport material and heat from the permanently irradiated dayside to the permanently shadowed nightside.

TLDR

Cornell says its international research team used JWST observations to resolve an exoplanet’s uneven contours for the first time. The hot Jupiter WASP-17b appears slightly egg-shaped, with one side extending farther. Cornell says the shape shows how intense heat and winds affect its atmosphere.
