Milky Way's Central Bulge (IMAGE) NASA/Goddard Space Flight Center Caption This is a ground-based view of the Milky Way's central bulge, seen in the direction of the constellation Sagittarius. Giant dust clouds block most of the starlight coming from the galactic center. Hubble however, peered through a region (marked by the arrow) called the Sagittarius Window, which offers a keyhole view into the galaxy's hub. Credit Credits: A.
