The Ultraviolet Imaging Spectrograph (UVS) will take pictures of Jupiter’s auroras in ultraviolet light. Working with Juno’s JADE and JEDI instruments, which measure the particles that create the auroras, UVS will help us understand the relationship between the auroras, the streaming particles and the magnetosphere as a whole. The Hubble Space Telescope took some impressive images of Jupiter’s auroras, but Juno will get an even better view – looking directly down on them over the north and south poles. UVS includes a scan mirror for targeting specific auroral features. UVS is sensitive to both extreme and far-ultraviolet light, within a wavelength range of 70 to 205 nanometers (billionths of a meter). In comparison, visible light has wavelengths that range from 400 to 700 nanometers. Dr. Randy Gladstone of Southwest Research Institute (SwRI) leads the UVS team. SwRI provided the UVS instrument. CSL/BELSPO (Belgium) contributed the scan mirror.
