Chandra Release - October 25, 2007 Visual Description: GOODS Chandra Deep Field-South The 2-panel features an illustration at left, and an image at right, of an active galactic nucleus (AGN) in a region of the Great Observatory Origins Deep Survey, or GOODS, known as Chandra Deep Field-South. The dominant colors in the image at right are blue, yellow and white. The shapes in the image are circular with patches of diffuse emission. The artist's illustration on the left shows a typical massive galaxy as it would have appeared when the universe was only about a quarter of its current age. This young galaxy contains an AGN, or quasar, in its center, a luminous object powered by the rapid growth of a supermassive black hole. Some of the light from the AGN is obscured by dense gas and dust near the center of the galaxy. The galaxy itself is undergoing a growth spurt, as shown by bright regions of star formation in its majestic spiral arms. The image on the right combines a Chandra X-ray Observatory image along with an infrared image as detected with the Spitzer Space Telescope. In the image, low-energy X-rays are shown in orange and high-energy X-rays in blue.
