Jupiter's icy moon, Europa, harbors a subsurface liquid water ocean; the prospect of this
ocean being habitable motivates further exploration of the moon with the upcoming NASA …

The Galilean moons play major roles in the giant magnetosphere of Jupiter. At the same
time, the magnetospheric particles and fields affect the moons. The impact of …

ABSTRACT Roth et al.(2014a) reported evidence for plumes of water venting from a
southern high latitude region on Europa: spectroscopic detection of off-limb line emission …

Ganymede's atmosphere is produced by charged particle sputtering and sublimation of its
icy surface. Previous far-ultraviolet observations of the O i 1,356 Å and O i 1,304 Å oxygen …

We calculate the time‐varying spatial distribution of energetic magnetospheric electron
influx onto Europa's surface by combining a hybrid model of the moon's draped …

Jupiter's moon Europa has a predominantly water-ice surface that is modified by exposure to
its space environment. Charged particles break molecular bonds in surface ice, thus …

The tenuous atmospheres of the Galilean satellites are sourced from their surfaces and
produced by a combination of plasma-surface interactions and thermal processes. Even …

Previous studies of the global intensities of the oxygen emissions at 1,356 Å and 1,304 Å
revealed molecular oxygen (O2) in Europa's atmosphere. Here we investigate the relative …

We analyze the magnetic field perturbations observed near Jupiter's icy moon Europa by the
Galileo spacecraft during the E26 flyby on 3 January 2000. In addition to the expected large …

Electron impact ionization is critical in producing the ionospheres on many planetary bodies
and, as discussed here, is critical for interpreting spacecraft and telescopic observations of …
