One of the larger conglomerations of mass in the universe, a cluster of galaxies known as Abell 370 was observed with the Hubble’s Advanced Camera for Surveys on July 16. Abell 370 is one of the first galaxy clusters where astronomers observed the phenomenon of gravitational lensing, in which the warping of space by the cluster’s gravitational field distorts the light from galaxies lying far behind it. This is manifested as arcs and streaks in the picture (for example the prominent arc known as the “dragon” galaxy, on the right-hand side), which are the stretched images of background galaxies 10 billion light-years away.
