Abell 370 is a galaxy cluster located approximately 6 billion light-years away from the Earth (at redshift z = 0.375), in the constellation Cetus. Its core is made up of several hundred galaxies. It was catalogued by George Abell, and this is the most distant of the clusters he catalogued. Abell 370 includes several distorted arcs of lensed light, where the lens in fact is a entire cluster of galaxies showing more several distant galaxies from the farest background.
