(Left) Locations of Hubble's observations of the MACS  J1149 galaxy cluster, top, and the nearby parallel field, bottom, plotted over a Digital Sky Survey (DSS) image. The blue boxes outline the regions of Hubble's visible light observations, and the red boxes indicate areas of Hubble's infrared light observations. The 1' bar, read as one arcminute, corresponds to approximately 1/30 the apparent width of the full moon as seen from Earth.
