                        Astronomy Picture of the Day

    Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: Dominated by dark matter, massive cluster of galaxies
   Abell 2744 is known to some as Pandora's Cluster. It lies 3.5 billion
   light-years away toward the constellation Sculptor. Using the galaxy
   cluster's enormous mass as a gravitational lens to warp spacetime and
   magnify even more distant objects directly behind it, astronomers have
   found a background galaxy, UHZ1, at a remarkable redshift of Z=10.1.
   That puts UHZ1 far beyond Abell 2744, at a distance of 13.2 billion
   light-years, seen when our universe was about 3 percent of its current
   age. UHZ1 is identified in the insets of this composited image
   combining X-rays (purple hues) from the spacebased Chandra X-ray
   Observatory and infrared light from the James Webb Space Telescope. The
   X-ray emission from UHZ1 detected in the Chandra data is the telltale
   signature of a growing supermassive black hole at the center of the
   ultra high redshift galaxy. That makes UHZ1's growing black hole the
   most distant black hole ever detected in X-rays, a result that now
   hints at how and when the first supermassive black holes in the
   universe formed.
