Jupiter is shown in visible light for context underneath an artistic impression of the Jovian upper atmosphere’s infrared glow. The brightness of this upper atmosphere…
In geospace, the Arase satellite observes chorus waves and energetic electrons, while on the ground, EISCAT and optical instruments observe pulsating aurorae and electron precipitation…
NASA’s Juno Mission observed pulsating electromagnetic ion cyclotron waves in Jupiter’s dawn magnetosphere that periodically expel energetic heavy ions into the atmosphere, producing stunning X-ray…
The purple hues in this image show X-ray emissions from Jupiter’s auroras, detected by NASA’s Chandra Space Telescope in 2007. They are overlaid on an…
