The galactic center
A composite image of the center of the Milky Way taken with three space-based telescopes. X-rays detected by the Chandra X-ray Observatory are represented in blue and violet, near-infrared light seen by the Hubble Space Telescope is yellow and infrared light captured by the Spitzer Space Telescope is red. The image covers one-half of a degree in the sky, about the width of the full moon. The bright blob of X-ray light in the picture's center-right is Sagittarius A, which contains a suspected supermassive black hole.
