Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...

Curves are shown for various power-law indices ? el of the electron spectrum and magnetic field strengths B . The angle between the line of sight and the magnetic field is 45 degree.

... 2006 February 13 . The N44 Emission Nebula . ... Located in our galactic neighbor the Large Magellanic Cloud , N44 houses numerous massive bright stars, lengthy lanes of dark dust , and vast clouds of hydrogen gas that glows red. The red color of the N44 emission nebula comes from pervasive hydrogen atoms re-acquiring electron s that were knocked away by energetic light from massive stars. ... N44, pictured above , spans about 1,000 light years and lies about 170,000 light years distant. ...

Plasma phenomena occuring at one place in the magnetosphere also affect other locations This linkage is most pronounced between points that share the same field line, since field lines guide the motion of ions and electrons. ... It follows that the places on Earth most sensitive to distant magnetic effects are the "polar caps" , the regions around the magnetic poles.
