Term Definition
Baade’s Window
An area of sky around the globular cluster NGC 6522 in the constellation Sagittarius, which is particularly rich in stars. The German-American astronomer Walter Baade 1893-1960 drew attention to the area and correctly deduced that it is a region in the disc of our Galaxy relatively clear of interstellar material through which very distant stars in the Galaxy’s nuclear bulge can be seen.
