Jupiter's largest moon, Ganymede, is bigger than planet Mercury -- and is blanketed in thin clouds of hydrogen peroxide, as seen in a remarkable new image from JWST. https://news.berkeley.edu/2023/07/27/james-webb-space-telescope-sees-jupiter-moons-in-a-new-light/ #space #science #JWST
James Webb Space Telescope sees Jupiter moons in a new light

NASA’s new space telescope uses its high-resolution spectrometer to find hydrogen peroxide around Ganymede’s poles and sulfur monoxide emerging from Io’s volcanos

JWST also turned its infrared eyes on another Jupiter moon, Io. The resulting views show sulfur emissions spewing from huge eruptions.
Io is the most volcanic world in the solar system, constantly in turmoil due to intense gravitational interactions with Jupiter and its other moons.

@coreyspowell I am a little surprised that JWST was not overwhelmed by the high temperature of Io.
