Galaxy Cluster Abell 2744: A Hubble Image Tour
Abell 2744 is a cluster of galaxies 5 million light-years across and 3.5 billion light-years away. Its immense mass has warped space, magnifying and distorting light from galaxies beyond the cluster, and giving us a view into the universe as it existed more than 13 billion years ago.
Explore the science along with the scenery – Image Tours show Hubble pictures through an astronomer's eyes, pinpointing and explaining key features to add understanding to the joy of cosmic sightseeing.
