Thousands of galaxies flood this near-infrared image of galaxy cluster SMACS 0723. These are images of background galaxies that have been stretched and distorted by the foreground galaxy cluster.
They follow invisible concentric circles that curve around the center of the image. There are also many thin, long, orange arcs. In the center of the image, between 4 o’clock and 6 o’clock in the bright star’s spikes, are several bright, white galaxies. It has eight blue, long diffraction spikes. Some look as large as the galaxies that appear next to them.Ī very bright star is slightly off center. Most appear blue with diffraction spikes, forming eight-pointed star shapes. In front of the galaxies are several foreground stars. Most appear as fuzzy ovals, but a few have distinctive spiral arms. Some are shades of orange, others are white. Thousands of small galaxies appear across the image. They include foreground stars, galaxies in a galaxy cluster, and distorted background galaxies behind the galaxy cluster. This image shows many overlapping objects at various distances.
