Thanks to a cluster of galaxies called Abell 383, astronomers were able to find a galaxy that formed when the universe was just 950 million years old. In the above picture from the NASA/ ESA Hubble Space Telescope, released April 13, this early galaxy appears as a faint dot just above the bright central galaxy.
The distant galaxy was detected using a phenomenon called gravitational lensing. The many galaxies in the Abell 383 cluster are collectively so massive that their gravity acts like a huge magnifying glass, bending and amplifying light from objects behind the cluster.
