X-Ray Vision

chandra-deep-field-southThis image was made with over 7 million seconds (about 11-1/2 weeks) of Chandra X-Ray Observatory observing time. It’s part of the Chandra Deep Field-South and is the deepest X-ray image ever obtained. This look at the early Universe in X-rays 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.
