Close-up observations of auroras on Jupiter (December 2023)

The NASA/ESA/CSA James Webb Space Telescope has captured new details of the auroras on our Solar System’s largest planet. The dancing lights observed on Jupiter are hundreds of times brighter than those seen on Earth.

These observations of Jupiter’s auroras were captured with Webb’s Near-InfraRed Camera (NIRCam) on 25 December 2023. 

Scientists found that the emission from the trihydrogen ion, known as H3+, is far more variable than previously believed. H3+ is created by the impact of high energy electrons on molecular hydrogen. Because this emission shines brightly in the infrared, Webb’s instruments are well equipped to observe it.
