Jupiter's magnetic auroras are a fascinating phenomenon that occurs when high-energy particles from the solar wind enter Jupiter's atmosphere near its magnetic poles and collide with gas atoms. These collisions cause the gas atoms to emit light, which creates the colorful and dynamic auroras seen in the images captured by the James Webb Space Telescope.

Jupiter has an incredibly strong magnetic field, which is about 20,000 times stronger than Earth's magnetic field. This magnetic field is generated by the churning motion of electrically conducting materials within Jupiter's core, such as metallic hydrogen. This magnetic field traps charged particles, such as electrons and protons, in radiation belts around the planet. When these particles collide with gas atoms in Jupiter's atmosphere, they produce the auroras.

On August 22, 2022 NASA’s James Webb Space Telescope presented data of Jupiter’s electromagnetic Auroras and Rings. Technically the images of Jupiter were taken by JWST on July 27, 2022. But actual image processing happened on August 22, 2022 by scientist Judy Schmidt and Ricardo Hueso (UPV/EHU). On the images you can see incredible phenomena of Jupiter’s Ring and Auroras. There are also moons Amalthea and Adrastea. These auroras are created when high-energy particles enter a planet’s atmosphere near its magnetic poles and collide with atoms of gas. Video of Jupiter’s aurora recorded by Juno spacecraft. I personally processed all source images to present them in 4K resolution.
