Astronomy Picture of the Day

   [1]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: [5]Dominated by dark matter, massive cluster of galaxies
   Abell 2744 is known to some as [6]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
   [7]redshift of [8]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. [9]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
   [10]black holes in the universe formed.
