caption_attribution_description: English: Saturn eclipsing the sun, seen from behind from the Cassini orbiter. The image is a composite assembled from images taken by the Cassini spacecraft on 15 September, 2006. Individual rings seen include (in order, starting from most distant) E ring Pallene ring (visible very faintly in an arc just below Saturn) G ring Janus/Epimetheus ring (faint) F ring (narrow brightest feature) Main rings (A,B,C) D ring (bluish, nearest Saturn) At full resolution, the distant Earth is visible as a dot above the left extremity of the main set of rings. For a detailed description, see http://photojournal.jpl.nasa.gov/catalog/PIA08329 and http://saturn.jpl.nasa.gov/news/press-release-details.cfm?newsID=698. Français&#160;: Saturne éclipsant le soleil, vu par la sonde cassini. Image composite. Les anneaux visibles sur cette photo sont (du plus externe au plus interne) Anneau E Anneau de Pallene (seul un arc est très faiblement visible juste sous Saturne) Anneau G Anneau de Janus et Epimetheus (faiblement visible) Anneau F (très brillant et étroit) Anneaux principaux (A,B,C) Anneau D (bleuâtre)
context_page_description: In physics, telecommunications, and astronomy, forward scatter is the deflection—by diffraction, nonhomogeneous refraction, or nonspecular reflection by particulate matter of dimensions that are large with respect to the wavelength in question but small with respect to the beam diameter—of a portion of an incident electromagnetic wave, in such a manner that the energy so deflected propagates in a direction that is within 90° of the direction of propagation of the incident wave.
  The scattering process may be sensitive to polarization; that is, the polarization of incident waves that are identical in every respect may be scattered differently. Forward scatter differs from backscatter.

caption: Saturn eclipses the Sun, as seen from the Cassini space probe. The forward scattering of light makes the faint outer rings more visible.
