Near-infrared light is dominated over much of the <Milky Way> by old, cool, low-mass stars, with extra emission from young stars and hot dust in active regions. Because <interstellar dust> attenuates it much less strongly than optical light, near-infrared surface brightness and star counts are useful tracers of stellar mass and the obscured Galactic bulge and bar.
