As one of the most geologically active bodies in the solar system, Saturn's moon Enceladus not only coats itself with water ice particles, it accounts for the unusually high albedos of the other satellites orbiting within Saturn's vast, tenuous E ring. This effect is evident in Hubble Space Telescope observations obtained at true opposition on 13 and 14 January 2005 that reveal that the mean geometric albedos of satellites embedded within the E ring approximate or exceed unity.

Enceladus: An Active Ice World in the Saturn System
Enceladus, one of the mid-sized icy moons of Saturn, has an importance to planetary science far greater than its modest 504-km diameter would suggest. Intensive exploration of Enceladus by the… Expand
Particle deposition on the saturnian satellites from ephemeral cryovolcanism on Enceladus
The geologically active south pole of Enceladus generates a plume of micron-sized particles, which likely form Saturn's tenuous E-ring extending from the orbit of Mimas to Titan. Interactions between… Expand

Enceladus is one of the most remarkable satellites in the solar system, as revealed by Cassini's detection of active plumes erupting from warm fractures near its south pole. This discovery makes… Expand
Physical properties of the small moon Aegaeon (Saturn LIII)
Aegaeon (Saturn LIII) is located within an arc of debris near the inner edge of Saturn’s G ring [1], and is the currently the smallest isolated moon of Saturn known [2]. On January 27, 2010 the… Expand
The surface composition of Enceladus: clues from the Ultraviolet
Abstract The reflectance of Saturn's moon Enceladus has been measured at far ultraviolet (FUV) wavelengths (115–190 nm) by Cassini's UltraViolet Imaging Spectrograph (UVIS). At visible and near… Expand

Icy Satellites: Geological Evolution and Surface Processes
The sizes of the Saturnian icy satellites range from ~ 1;500 km in diameter (Rhea) to ~20km (Calypso), and even smaller ‘rocks’ of only a kilometer in diameter are common in the system. All these… Expand
Cassini's geological and compositional view of Tethys
Abstract The Saturnian satellite Tethys exhibits geological and spectral properties, whose appearance, nature and spatial distribution partly mirror those identified on the neighboring satellites… Expand

Cassini Observes the Active South Pole of Enceladus
TLDR
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance. Expand
Origin of Saturn's E Ring: Self-Sustained, Naturally
TLDR
This model naturally selects Enceladus as the primary source of ring material and may also provide mechanisms that explain the generation of the unusual amount of submicrometer dust in the neighboring F and G rings, the excess of OH molecules observed within the E ring, and the orbital brightness variations of nearby satellites.
