Caption: This extremely deep Chandra X-ray Observatory image has resolved a long-standing mystery about an X-ray glow along the plane of the Milky Way. The Chandra results show that the X-ray emission in the region is caused by hundreds of point-like sources, implying that the glow along the plane of the Galaxy is due to millions of such sources. In this image, the Chandra field-of-view, a region located only about 1.4 degrees from the Galactic Center, is pulled out from an infrared image from the Spitzer Space Telescope.

Scale: Inset Image is 5.1 arcmin across.
