1. Particle Sizes in Saturns Rings
... Particle Sizes in Saturns Rings . ... Credit: RSS , JPL , ESA , NASA Explanation: What size particles compose Saturn's rings? To help find out, the robot Cassini spacecraft now orbiting Saturn broadcast radio waves of three different wavelengths right through the rings to Earth earlier this month. The experiment was sensitive to ring particle sizes because ring particles much larger than a broadcast radio wavelength will reflect those radio waves away. ... NASA Official: Jay Norris. ...

2. APOD: 2005 May 25 - Particle Sizes in Saturns Rings
... Particle Sizes in Saturn's Rings . ... Explanation: What size particles compose Saturn's rings? ... The experiment was sensitive to ring particle sizes because ring particles much larger than a broadcast radio wavelength will reflect those radio waves away. ... The white center of Saturn's B-ring indicates that the density of ring particles was too high to make a good determination. Other radio observations indicate that some ring particles can be as large as several meters across. ...

4. The Effects of Dust in Simple Environments: Large Magellanic Cloud H II Regions
We investigate the effects of dust on Large Magellanic Cloud (LMC) H II region spectral energy distributions using arcminute-resolution far-ultraviolet (FUV), HЮБ, far-infrared (FIR), and radio images. Widely used indicators of the amount of light lost to dust (attenuation) at HЮБ and in the FUV correlate with each other, although often with substantial scatter. ...

14. H I Midplane Poster for the 201st Meeting of the AAS, January, 2003
Presented on Tuesday, January 7, 2003 . We construct a detailed longitude-velocity diagram through the actual midplane of the Galactic H I disk. The Galactic midplane definition is based on single-dish sky surveys, and the detailed l-v slice ( Fig. 1 ) is extracted from the Canadian Galactic Plane Survey ( CGPS ; Taylor et al. 2003 ). ... Note: other slices offset from this one were not shown in the AAS poster for lack of space, but they are available here . ...

15. The Earth's Magnetosphere
... A typical density of energetic ions is 1 per cubic cm., and the ions are matched by electrons, generally of lower energy. ... This region is almost empty of plasma--typical density 0.01 ion/cubic cm., the "best vacuum" in the Earth's vicinity--but it contains a relatively strong magnetic field which, since it fills a large volume, can store appreciable magnetic energy, Many believe that this is the storehouse from which substorms draw their energy, releasing it quite rapidly. ...
