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 is the most distant of the clusters he catalogued.
In 2009, study in the field of Abell 370 revealed a grouping of background galaxies lensed and distorted by the cluster into an arc with the appearance of a dragon, hence nicknamed The Dragon by NASA scientists. Its head is composed of a spiral galaxy, with another spiral composing the tail. Several other galaxies form the body of the dragon, all overlapping. These galaxies all lie approximately 5 billion light years away.
