This Hubble image shows the galaxy cluster Abell 2813. The color image was compiled using observations taken with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) instruments. Several filters were used to sample various optical wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Four of the newfound quadruply-imaged quasars are shown here; from top left and moving clockwise, the objects are: GraL J1537-3010 or Wolf’s Paw; GraL J0659+1629 or Gemini’s Crossbow; GraL J1651-0417 or Dragon’s Kite; GraL J2038-4008 or Microscope Lens. The fuzzy dot in the middle of the images is the lensing galaxy, the gravity of which is splitting the light from the quasar behind it in such a way to produce four quasar images.
