In astronomy, surface brightness (SB) quantifies the apparent brightness or flux density per unit angular area of a spatially extended object such as a galaxy or nebula, or of the night sky background. An object's surface brightness depends on its surface luminosity density, i.e., its luminosity emitted per unit surface area. In visible and infrared astronomy, surface brightness is often quoted on a magnitude scale, in magnitudes per square arcsecond (MPSAS) in a particular fil… WebIt is assumed that the fluctuation of brightness in the Milky Way are caused by irregularities in the distribution of absorbing clouds in Galaxy. A theory of these fluctuations is given in the simple case, when all absorbing clouds have equal optical thickness. January, 1943
