  journal={The Astrophysical Journal},
We report new observations of the spectrum of Ganymede in the spectral range 1160-1720 A made with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST) on 1998 October 30. The observations were undertaken to locate the regions of the atomic oxygen emissions at 1304 and 1356 A, previously observed with the Goddard High Resolution Spectrograph on HST, that Hall et al. claimed indicated the presence of polar aurorae on Ganymede. The use of the 2'' wide STIS slit… Expand

Aurora on Ganymede
[1] We present four sets of ultraviolet images of Ganymede acquired with the Hubble Space Telescope (HST) from 1998 to 2007, all of which show auroral emission from electron excited atomic oxygen.Expand

Europa's far ultraviolet oxygen aurora from a comprehensive set of HST observations
We analyze a large set of far ultraviolet oxygen aurora images of Europa's atmosphere taken by Hubble's Space Telescope Imaging Spectrograph (HST/STIS) in 1999 and on 19 occasions between 2012 andExpand
Isolating auroral FUV emission lines using compact, broadband instrumentation.
Abstract Images of auroral emissions at far ultraviolet (FUV, 122–200 nm) wavelengths are useful tools with which to study magnetospheric–ionospheric coupling, as the scattered sunlight background inExpand
Evidence for a sublimated water atmosphere on Ganymede from Hubble Space Telescope observations
Ganymede’s atmosphere is produced by charged particle sputtering and sublimation of its icy surface. Previous far-ultraviolet observations of the OI 1356-Å and OI 1304-Å oxygen emissions were used toExpand
The search for a subsurface ocean in Ganymede with Hubble Space Telescope observations of its auroral ovals
We present a new approach to search for a subsurface ocean within Ganymede through observations and modeling of the dynamics of its auroral ovals. The locations of the auroral ovals oscillate due toExpand
Emission profiles of neutral oxygen and sulfur in Io's exospheric corona
Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) observations of Io acquired in 1997 [Roesler et al., 1999] provided the first simultaneous spatially resolved measurements ofExpand
Ultraviolet observations of Phoebe from the Cassini UVIS
Observations of Saturn’s distant moon Phoebe were made at far-ultraviolet (FUV) (1100–1900 A) and extreme-ultraviolet (EUV) (600–1100 A) wavelengths by the Cassini Ultraviolet Imaging SpectrographExpand
Orbital apocenter is not a sufficient condition for HST/STIS detection of Europa’s water vapor aurora
The new observations indicate that although the same orbital position of Europa for plume activity may be a necessary condition, it is not a sufficient condition, and Orbital position is therefore not asufficient condition for detecting plumes and they may be episodic events. Expand
Ultraviolet emissions from the magnetic footprints of Io, Ganymede and Europa on Jupiter
It is shown that Io's magnetic footprint extends well beyond the immediate vicinity of Io's flux-tube interaction with Jupiter, and much farther than predicted theoretically; the emission persists for several hours downstream. Expand


The Far-Ultraviolet Oxygen Airglow of Europa and Ganymede
Far-UV spectra of Europa and Ganymede, acquired by the Hubble Space Telescope Goddard High Resolution Spectrograph, indicate that, in addition to faintly reflected sunlight, both satellites emit O IExpand

Overview of the Voyager ultraviolet spectrometry results through Jupiter encounter
The Voyager ultraviolet spectrometers (UVS) have been making almost continuous observations, in the 500-A to 1700-A wavelength range, of sources in the solar system and galaxy since launch in 1977.Expand
Charge‐coupled device spectra of the Galilean satellites: Molecular oxygen on Ganymede
We have obtained 3200–7800 A CCD spectra of the Galilean satellites at a variety of orbital longitudes, with spectral resolution between 3 and 18 A and signal-to-noise ratios of up to 2000 at 6000 A.Expand
Evidence for a magnetosphere at Ganymede from plasma-wave observations by the Galileo spacecraft

Detection of Ozone on Ganymede
An absorption band at 260 nanometers on the trailing hemisphere of Ganymede, identified as the Hartley band of ozone (O3), was measured with the Hubble Space Telescope, and apparently this O2-O3 “atmosphere” is trapped in GanyMede's surface ice, an inference consistent with the shift and broadening of the band.
