Baade's Window
From Wikipedia, the free encyclopedia
Baade's Window is a region with relatively low amounts of interstellar "dust" along our line of sight and is a "window" because in this direction we are able to see all the way to the Milky Way Galactic Center (actually, somewhat "south" of the center, in the central bulge) and beyond. It is named after the German astronomer Walter Baade.
Baade's Window is used to inspect distant stars and to determine the internal geometry of the Milky Way. It lies towards the constellation of Sagittarius.
