Made with over 7 million seconds of Chandra observing time, this image is part of the Chandra Deep Field-South and is the deepest X-ray image ever obtained. With its unprecedented look at the early Universe in X-rays, the CDF-S gives astronomers the best look yet at the growth of black holes over billions of years starting soon after the Big Bang. In this image, low, medium, and high-energy X-rays that Chandra detects are shown as red, green, and blue respectively.
