    • Mapping the Brightness of Ganymede's Ultraviolet Aurora Using Hubble Space Telescope Observations 

      Marzok, A.; Schlegel, S.ORCIDiD; Saur, J.ORCIDiD; Roth, L.ORCIDiD; Grodent, D.ORCIDiD; Strobel, D. F.ORCIDiD; Retherford, K. D.ORCIDiD (Journal of Geophysical Research: Planets, 2022-06-15)
      We analyze Hubble Space Telescope observations of Ganymede made with the Space Telescope Imaging Spectrograph between 1998 and 2017 to generate a brightness map of Ganymede's oxygen emission at 1,356 Å. Our Mercator projected ...
