This color-composite shows a main part of the new Blanco DECam Bulge Survey of 250 million stars in our galaxys bulge. The 4 x 2 degrees excerpt can be explored in all its whopping 50,000 x 25,000 pixels in this zoomable version. In the image interstellar dust and gas seemingly acts like a red filter in front of the background stars, scattering the blue light away. Since we are surrounded by dust and gas in the Milky Way, this scattering effect is important to many parts of astronomy and is known as interstellar reddening. DECam was primarily funded by the U.S. Department of Energy.
