تفصیلJupiter.Aurora.HST.UV.jpg	Deutsch: Bild von ultraviolettem Polarlicht auf Jupiter, aufgenommen mit dem Space Telescope Imaging Spectrograph (STIS) des Weltraumteleskops Hubble der NASA. • STScI-PRC00-38 Helle Streifen und Tupfen sind verursacht durch magnetischen Flussröhren, die Jupiter mit seinen größten Monden verbindet: Io: heller Streifen ganz links, Ganymed: heller Tupfer unterhalb der Bildmitte, Europa: Tupfer rechts dessen von Ganymed English: This is a spectacular NASA Hubble Space Telescope close-up view of an electric-blue aurora that is eerily glowing one half billion miles away on the giant planet Jupiter. Auroras are curtains of light resulting from high-energy electrons racing along the planet's magnetic field into the upper atmosphere. The electrons excite atmospheric gases, causing them to glow. The image shows the main oval of the aurora, which is centered on the magnetic north pole, plus more diffuse emissions inside the polar cap. Though the aurora resembles the same phenomenon that crowns Earth's polar regions, the Hubble image shows unique emissions from the magnetic "footprints" of three of Jupiter's largest moons. (These points are reached by following Jupiter's magnetic field from each satellite down to the planet). Auroral footprints can be seen in this image from Io (along the left hand limb), Ganymede (near the center), and Europa (just below and to the right of Ganymede's auroral footprint). These emissions, produced by electric currents generated by the satellites, flow along Jupiter's magnetic field, bouncing in and out of the upper atmosphere. They are unlike anything seen on Earth. This ultraviolet image of Jupiter was taken with the Hubble Space Telescope Imaging Spectrograph (STIS) on November 26, 1998. In this ultraviolet view, the aurora stands out clearly, but Jupiter's cloud structure is masked by haze. This image was taken in UV light at 140 nm.
