The Figure below shows the 25 micron weekly maps from DIRBE as an animated GIF file. At this wavelength, the zodiacal emission dominates the sky, so only a very thin galactic plane emission can be seen over the interplanetary dust.
From the time variation of the intensity at a given point on the sky, it is possible to estimate the zodiacal intensity without prejudging the cosmic or galactic backgrounds.
