This image shows a massive galaxy cluster embedded in the middle of a field of nearly 8,000 galaxies scattered across space and time. This "galaxies galore" snapshot is from a new Hubble Space Telescope survey to boldly expand its view by significantly enlarging the area covered around huge galaxy clusters previously photographed by Hubble. In this view the huge cluster Abell 370, located about 4 billion light-years away, lies in the center of this image. It contains several hundred galaxies. The mosaic of fields flanking the cluster contains myriad background galaxies flung across space and time.
