Thank you Ann and Bruce. Jerry Bonnell (UMCP) The clusters are over 7,000 light years distant toward the constellation of Perseus, but are separated by only hundreds of light years. The picture (right) captures an area about 1.5 million light years wide. The Perseus cluster is also fairly close to the plane of the Milky Way, so a lot of the faintest points of light in this image are actually foreground stars … Perseus’s borders contain a massive galaxy cluster, about 250 million light-years away. The clusters are over 7,000 light years distant toward the constellation of Perseus, but are separated by only hundreds of light years. However, the true nature of the Double Cluster was not discovered until the invention of the telescope, many centuries later.
