TL;DR: Observations by the Galileo spacecraft and the Keck telescope showed that Jupiter's outermost (gossamer) ring is actually two rings circumscribed by the orbits of the small satellites Amalthea and Thebe, suggesting that faint rings may accompany all small inner satellites of the other jovian planets.

TL;DR: In this paper, the first two moments of the size distribution, the single-scattering albedo, the dust singlescattering phase function, and the imaginary index of refraction were analyzed for a lognormal particle size distribution.

TL;DR: A new wavelength-dependent model of the single-scattering properties of the Martian dust is presented and is compared to observations taken by the Viking Orbiter Infrared Thermal Mapper solar channel instrument during two dust storms, which accurately matches afternoon observations and some morning observations.

TL;DR: In this article, the authors report an analysis of the orientation and distribution of these surface features, based on initial observations made by the Galileo spacecraft, and find evidence that Europa spins faster than the synchronous rate (or did so in the past), consistent with the possibility of a global subsurface ocean.

TL;DR: In this paper, four distinct classes of lineaments can be described on the basis of Galileo's improved spectral and spatial coverage of Europa: (1) incipient cracks are narrow; (2) the morphologies, spectral properties, and orientations of the lineaments vary systematically with age; (3) these four classes represent different stages of development in an evolutionary sequence; and (4) the bright band Agenor Linea is among the leading candidates for current activity.
