The Voyager 2 photopolarimeter successfully completed the Uranus encounter, acquiring new data on the planet's atmosphere, its principal satellites, and its ring system. Spatially resolved photometry of the atmosphere at 0.27 micrometer shows no enhancement in absorption toward the pole, unlike the case for Jupiter and Saturn. Stellar occultation measurements indicate the temperature at the 1-millibar level over the north pole is near 90 kelvins. The geometric albedos of the five large… 
The Ring System of Uranus: Flat as a Pancake, Sprinkled with Dust
We present a high quality image of the uranian ring system, obtained in July 2004 at 2.2 {micro}m with the adaptive optics camera NIRC2 on the Keck II telescope. Using these data, we report the first
Dusty Rings and Circumplanetary Dust: Observations and Simple Physics
Each giant planet is encircled by planetary rings, usually composed of particles centimeters to meters in radius, but each system also contains regions where much smaller dust grains predominate.
The Atmospheric Structure of the Ice Giant Planets from In Situ Measurements by Entry Probes
We aim at investigating the atmosphere of Uranus and Neptune, the Ice Giants of our Solar System by means of an atmospheric entry probe. The measurements performed all along the probe descent down
Size-Dependent Scattering Properties of Planetary Regolith Analogs
The physics of the interaction of light with a particulate surface are important to understanding and analyzing remote sensing data from planetary surfaces. An examination of the angular scattering
