Title -  Massive Cluster of Galaxies Captured by Hubble

 

Description -  A massive cluster of galaxies called Abell 2218.  This cluster resides in the constellation Draco, some 2 billion light-years from Earth.  The cluster is so massive that its enormous gravitational field deflects light rays passing through it, much as an optical lens bends light to form an image.  This phenomenon, called gravitational lensing, magnifies, brightens, and distorts images from faraway objects.  The cluster's magnifying powers provides a powerful "zoom lens" for viewing distant galaxies that could not normally be observed with the largest telescopes.  The picture is dominated by spiral and elliptical galaxies.
