Baade’s Window

Baade's Window provides a view through the occluding material of the Milky Way into the regions near the Galaxy's core. The two bright objects seen here are not stars, but ancient globular clusters in the central parts of the Milky Way, each an estimated 25,000 light years or more from the Sun. Near the centre of this view is NGC 6522, while to the east (left) is NGC 6528. Imagery provided by Aladin sky atlas
