Chandra Release - March 28, 2002 Visual Description: SDSS 0836+0054, 1030+0524 & 1306+0356 X-ray images of three different quasars, discovered at optical wavelengths by the Sloan Digital Sky Survey (SDSS), are shown in a three-panel image with two images up top and one below them. At 13 billion light years from Earth, these are the most distant known quasars at the time of observation. The X-rays Chandra detected were emitted when the universe was only a billion years old, about 7 percent of the present age of the universe. In each of the three images, the brightest part of the quasar appears as a strong orange dot in the middle of a black background with a white arrow pointing to it. The upper left and bottom images have one and two additional softer orange background sources, respectively. The quasar objects’ names are written in each image box, from top left to bottom: SDSS 0836+0054, SDSS 1030+0524 and SDSS 1306+0356.
