... Simeis 188 in Stars, Dust and Gas . ... A particularly colorful case is the star forming region Simeis 188 which houses an unusual and bright cloud arc cataloged as NGC 6559 . Visible above are red glowing emission nebulas of hydrogen , blue reflection nebulas of dust , dark absorption nebulas of dust, and the stars that formed from them. ... After tens of millions of years, the dust boils away, the gas gets swept away, and all that is left is a naked open cluster of stars. ...

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 . ...
