Europa's Plumes Jupiter's moon Europa has a subsurface ocean and a relatively young icy surface. Roth et al. (p. 171, published online 12 December 2013; see the Perspective by Spencer) analyzed spectral images taken by the Hubble Space Telescope that show ultraviolet emissions from the moon's atmosphere, and report a statistically significant emission signal extending above the satellite's southern hemisphere. This emission is consistent with two 200-km-high plumes of water vapor. Tidal… 
Evidence of a plume on Europa from Galileo magnetic and plasma wave signatures
The icy surface of Jupiter’s moon, Europa, is thought to lie on top of a global ocean1–4. Signatures in some Hubble Space Telescope images have been associated with putative water plumes rising above
Active Cryovolcanism on Europa?
Evidence for plumes of water on Europa has previously been found using the Hubble Space Telescope using two different observing techniques. Roth et al. found line emission from the dissociation
A magnetically driven equatorial jet in Europa’s ocean
During recent decades, data from space missions have provided strong evidence of deep liquid oceans underneath a thin outer icy crust on several moons of Jupiter1,2, particularly Europa3,4. But these
Modeling Europa's dust plumes
The discovery of Jupiter's moon Europa maintaining a probably sporadic water vapor plume constitutes a huge scientific opportunity for NASA's upcoming mission to this Galilean moon. Measuring
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.
Modelling of Europa's plumes
There are now three types of atmospheric observations suggesting the existence of plumes at Europa’s surface: H I and O I ultraviolet (UV) emission excited by the dissociation of water vapor in the
Magnetic Signatures of a Plume at Europa During the Galileo E26 Flyby
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‐scale
The feasibility of in-situ observations of Europa's water vapour plumes.
Europa, the second of Jupiter’s Galilean moons, has attracted strong interest from the scientific community. This is because it could harbour a sub-surface ocean of liquid water beneath its icy
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 and


Evidence for a subsurface ocean on Europa
High-resolution Galileo spacecraft images of Europa are presented, in which evidence for mobile ‘icebergs’ is found and the detailed morphology of the terrain strongly supports the presence of liquid water at shallow depths below the surface, either today or at some time in the past.
We report results of a Hubble Space Telescope (HST) campaign with the Advanced Camera for Surveys to observe Europa at eastern elongation, i.e., Europa's leading side, on 2008 June 29. With five
Io's dayside SO2 atmosphere
The search for current geologic activity on Europa
Observational evidence and theoretical arguments suggest that Jupiter's satellite Europa could be geologically active and possess an “ocean” of liquid water beneath its surface at the present time.
The composition and structure of the Enceladus plume
The Cassini Ultraviolet Imaging Spectrograph (UVIS) observed an occultation of the Sun by the water vapor plume at the south polar region of Saturn's moon Enceladus. The Extreme Ultraviolet (EUV)
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 of
Induced magnetic fields as evidence for subsurface oceans in Europa and Callisto
P perturbations of the external magnetic fields (associated with Jupiter's inner magnetosphere) in the vicinity of both Europa and Callisto are reported, and it is argued that these conducting layers may best be explained by the presence of salty liquid-water oceans.
An observed correlation between plume activity and tidal stresses on Enceladus
It is reported that the plume’s horizontally integrated brightness is several times greater when Enceladus is near the point in its eccentric orbit where it is furthest from Saturn than it is when close to the point of closest approach to the planet.
