1. Particle Sizes in Saturns Rings
... Particle Sizes in Saturns Rings . ... Credit Copyright: 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. ...

3. APOD: 2013 July 10 - Large Sunspots Now Crossing the Sun
... 2013 July 10 . Large Sunspots Now Crossing the Sun . ... Explanation: One of the largest sunspot regions in recent years is now crossing the Sun. This region of convoluted magnetic fields may well produce a solar flare that releases a cloud of energetic particles into the Solar System. ... The darkest sunspot regions contain nearly vertical magnetic fields and are called umbras, while the surrounding bronze regions -- more clearly showing stringy magnetic flux tubes -- are called penumbras. ...

9. Density Determination
In order to measure the density of the Universe, it is necessary to sample a region that is larger than the scale on which the Universe becomes approximately homogeneous. ... When applied to clusters of galaxies we find a mass to luminosity ratio that implies a density of the Universe that is about 0.3 times the critical density. ... Thus the mass-to-muinosity ratio appears to vary with the size of the region measured, from 3 in the solar neighborhood to 30 in galaxies to 300 in clusters of galaxies. ...

14. Geometrical optics approximation (GO)
For particles of very large sizes, scattering can be considered as a result of interference of the rays having multiple reflections and refractions according to the laws of geometrical optics. ... The papers [ 413 , 414 ] presented a method where the scattering field was expressed via the field at the particle surface using the Huygens-Kirchhoff principle, and reflection and refraction laws were employed to find the unknown field (the approach was called physical optics approximation). ...

20. Different types of detector map
... A detector map is used to provide a grid of positions over which to calculate and flux weight the ARF. The default detector map is 'flat' which has a weighting of 1.0 for each detector map pixel and is rectangular having sides which just encompass the region specified in the DSS. Only detector map pixels falling within the source region are included in the ARF calculation, e.g. for a circular source box, the pixels in the corners of the detector map will be ignored. ... flat : . ...
