The Hubble Space Telescope's sharp view was used to look for gravitational arcs and rings (indicated by arrows in inserts above), which are produced when one galaxy acts as a lens to magnify and distort the appearance of another galaxy behind it. In this case, the foreground galaxies contain actively accreting black holes called quasars.
