This image is an x-ray survey taken in the constellation Bootes from the orbiting Chandra X-Ray telescope. Here’s an excerpt from their site describing what it is and how it was taken:
A new wide-field panorama reveals more than a thousand supermassive black holes in the centers of galaxies, some up to several billion times more massive than the sun. This survey, taken in a region of the Bootes constellation, involved 126 separate Chandra exposures of 5,000-seconds each, making it the largest contiguous field ever obtained by the observatory. At 9.3 square degrees, it is over 40 times larger than the full moon seen on the night sky, which is also shown in this graphic for scale. In this image, the red represents low-energy X-rays, green shows the medium range, and blue the higher energy X-rays.
