Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem have produced many new findings, including new saturnian moons; refined orbits of new and previously known moons; ring particle albedos in select ring regions; and never-before-seen phenomena within the rings.

Cassini Imaging Science: Initial Results on Phoebe and Iapetus
The Cassini Imaging Science Subsystem acquired high-resolution imaging data on the outer Saturnian moon, Phoebe, during Cassini's close flyby on 11 June 2004 and on Iapetus during a flyby on 31Expand
Imaging of Titan from the Cassini spacecraft
Observations of Titan from the imaging science experiment onboard the Cassini spacecraft reveal intricate surface albedo features that suggest aeolian, tectonic and fluvial processes, and imply that substantial surface modification has occurred over Titan's history. Expand
Cassini Imaging Science: Initial Results on Saturn's Atmosphere
From analysis of cloud motions through early October 2004, vertical wind shear in Saturn's equatorial jet and a maximum wind speed of ∼375 meters per second are reported, a value that differs from both Hubble Space Telescope and Voyager values. Expand
Linear Gas Dynamics in the Expanding Universe
We investigate the relationship between the dark matter and baryons in the linear regime. This relation is quantified by the so-called ‘‘ filtering scale.’’ We show that a simple Gaussian Ansatz thatExpand
The search for H- in astrophysical environments
The negative ion H− is widely understood to be important in many astrophysical environments, including the atmospheres of late-type stars like the Sun. However, the ion has never been detectedExpand
Close-range remote sensing of Saturn’s rings during Cassini’s ring-grazing orbits and Grand Finale
This work finds structures related to the detailed sculpting of rings by embedded masses, including structures near the moon Daphnis that have apparently experienced markedly different perturbations compared to the surrounding ring material, and complex structure elements within the largest propeller-shaped disturbances.
