Webb Unveils Atmosphere of Puffy Hot Jupiter WASP-17b
On October 14, 2026, astronomers using NASA's James Webb Space Telescope unraveled new atmospheric secrets of WASP-17b, a blisteringly hot exoplanet about 1,300 light-years away. 8 times Jupiter's mass but twice its width, the so-called super-puff has a marshmallow-like density and orbits its star in under four days.
With no prior findings on record, this marks the first detailed infrared look at its extreme atmosphere. The work showcases Webb's science value, supporting continued demand for advanced space optics and data analysis.
