This DECam photo, taken looking toward the center of our Milky Way galaxy, covers an area roughly twice as wide as the full moon and contains more than 180,000 stars. You can also see a wider version encompassing more of the Milky Way’s bulge. While beautiful, the stars and dust of the Milky Way block out distant galaxies needed to study dark energy — so the Dark Energy Survey typically aims the telescope in the opposite direction, away from the plane of our galaxy.
