Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies that existed 12.8 billion years ago. These galaxies, hosting faint quasars at their centers, could be the ancestors of the brightest and most massive quasars in the early Universe.

IC 4709’s swirling disk filled with stars and dust bands is beautifully captured by Hubble, as is the faint halo surrounding it. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M. Koss / A. Barth.
