    Download this episode


    A giant cluster of elliptical galaxies, called Abell 383, contains a large amount of matter, including dark matter. It has formed what is called a gravitational lens. This lens distorts and magnifies light from the more distant objects behind it. This process helped astronomers observe a young galaxy that formed early in the universe. The characteristics of this new object help explain what happened at the very beginning of the universe, not very long after the Big Bang.
