🔭 The James Webb Space Telescope (JWST) is on a roll, revealing jaw-dropping discoveries about Jupiter's fascinating moons, Ganymede and Io! 🔭

🌌 Ganymede - The Largest Moon's Hidden Secret 🌌 JWST's sensitive infrared cameras exposed hydrogen peroxide (H2O2) around Ganymede's poles, a first-time detection! 🌠 The moon's magnetic field directs charged particles from Jupiter's magnetosphere towards the poles, causing a captivating process called radiolysis, altering the polar caps' surface chemistry. 🌈 This exciting find sheds light on icy bodies' chemistry across the outer solar system, unlocking the secrets of neighboring moons like Europa and Callisto! 🪐

🌋 Io - Unraveling Sulfurous Volcanic Mysteries 🌋 Io's volcanic prowess comes to the fore with JWST's high-resolution spectrometer. The thermal infrared measurements captured intense eruptions at Kanehekili Fluctus and Loki Patera. 🌋🔥 Thanks to JWST's observations, scientists linked sulfur monoxide (SO) emissions to volcanic activity, deepening our knowledge of Io's extreme geology and atmosphere. 🌠🔍

🚀 Exciting Times for Astronomy! 🚀 JWST's Early Release Science program is unlocking the cosmos' hidden gems! 🌟 These discoveries highlight the importance of investing in advanced space telescopes to unravel the universe's mysteries. 🌌 Let's celebrate the triumphs of science and look forward to more groundbreaking revelations from the James Webb Space Telescope! 🎉

if you’re not familiar, jupiter has moons like earth, but just a crap ton of them, and one of them has the charming short name of “io”. while our moon is pretty chill and has a bunch of craters, io is crazy violent. it has a crap ton of volcanoes that erupt in massive... well... eruptions and sends up plumes 250 miles up. here’s a pic^
