Happy Friday

Abell 1703
Those fuzzy yellowish spots represent very large elliptical galaxies each comprised of billions of individual stars.  This dense galaxy cluster consisting of roughly 100 galaxies creates a gravitational field so intense it acts as a lens, magnifying and distorting galaxies lying behind the cluster.  Those graceful arcs and banana shapes reflect galaxies that are far more distant than the Abell cluster.   The Abell 1703 galaxy cluster is 3 billion light years from Earth.
