TLDR
The first ground-based images of the jovian halo and gossamer ring were obtained by the W. M. Keck telescope on August 14 and 15, 1997, when the ring plane was almost edge-on (opening angle β=0.17°) and near opposition (phase angle α≈1.1°).About:

The Structure of Jupiter's Ring System as Revealed by the Galileo Imaging Experiment
Maureen E. Ockert-Bell,Joseph A. Burns,Ingrid Daubar,Peter C. Thomas,Joseph Veverka,M. J. S. Belton,Kenneth P. Klaasen +6 more
TL;DR: The tenuous jovian ring system (normal optical depths <10−5) has three components: the halo, main ring, and gossamer ring as mentioned in this paper, which are observed during four orbits of Galileo's nominal mission, when 25 clear-filter images of the rings were taken at spatial resolutions of 23 to 134 km/pixel; the ring appeared fortuitously in an additional 11 images.

The lunar dust environment
TL;DR: The LADEE mission is scheduled to launch in early 2013 as discussed by the authors, where the highly sensitive Lunar Dust Experiment (LDEX) onboard the LADSEE mission will shed new light on the lunar dust environment.

Low velocity impacts into dust: results from the COLLIDE-2 microgravity experiment
TL;DR: The second flight of the Collisions Into Dust Experiment (COLLIDE-2) as mentioned in this paper, a space shuttle payload that performs six impact experiments into simulated planetary regolith at speeds between 1 and 100 cm/s.

A New System of Faint Near-Infrared Standard Stars
TL;DR: In this paper, a grid of 65 faint near-infrared standard stars is presented, which lie between 10th and 12th magnitude at K and are measured in most cases to precisions better than 0.001 mag in the J, H, K, and Ks bands; the latter is a medium-band modified K.

Determination of extraterrestrial solar spectral irradiance from a research aircraft.
TL;DR: Results are presented of an experiment to determine extraterrestrial solar spectral irradiance at the earth's mean solar distance within the 300-2500 nm wavelength region, with absolute accuracy of approximately +/-3% over most of the measurement range.

The formation of Jupiter's faint rings
Joseph A. Burns,Mark R. Showalter,Douglas P. Hamilton,Philip D. Nicholson,Imke de Pater,Maureen E. Ockert-Bell,Peter C. Thomas +6 more
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.

Structure and particle properties of Saturn's E Ring
TL;DR: In this article, a simple power-law model is found to describe the ring's normal optical depth profile with orbital radius; this trend is departed from, however, near the density peak, where there emerges a 30-percent localized decrease in thickness.
The ethereal rings of Jupiter and Saturn
TL;DR: The main band of the Jovian ring lies in the equatorial plane at 1.7-1.8 Jupiter radii, R(J); this is well within the Roche limit as discussed by the authors.
