Baade's Window is the largest of 6 relative dust free zones allowing astronomers to study stars in the central bulge of the Milky Way Galaxy. Nothing illustrates the billions of stars in our galaxy like a view of the view of the galactic center, even if only a tiny slice.
Also visible are two globular clusters, NGC 6522 at the center and NGC 6528 below. NGC 6522 is centered in the view of Baade's Window, and at an estimated age of 12 billion years makes it one of the oldest around our galaxy and lies at a distance of 25,100 light years. NGC 6528 is 25,800 light years distant and is unusually meta rich for a globular
The bright star in the lower left is W Sgr, which is a multiple star system, and the primary star is a classical Cepheid variable star that it's magnitude varies over 7 1/2 days.
