This photo, taken by the NASA/ESA Hubble Space Telescope, shows a variety of fascinating astronomical discoveries. On the right side of the image is a ring-shaped galaxy, in addition to several large elliptical galaxies. To the left of the image is a pair of bright stars that stand out with their vibrant, diagonal diffraction spikes. Visible in the constellation Pictor and photographed by Hubble's Advanced Camera for Surveys, the galaxy cluster ACO S520 is a collection of celestial wonders.
One of the Hubble observations looking for massive, bright galaxy clusters that have eluded past surveys is the ACO S520. With the help of Hubble and the NASA/ESA/CSA James Webb Space Telescope, astronomers were able to take pictures of these understudied galaxy clusters during occasional breaks in Hubble's busy schedule. This has revealed a number of interesting candidates for further investigation.
The largest known objects in the universe are galaxy clusters. Understanding the distribution of dark matter, the enigmatic matter that makes up most of a galaxy cluster's mass, can be learned by studying these objects.
