NGC 869 & 884 - Double Cluster in Perseus


NGC 869 and NGC 884 - the Double Cluster - lie 7,500 light years away in the constellation of Perseus. They are relatively young (12.8 million years old) and contain more than 300 super-giant stars. Both clusters are blue-shifted, meaning that they are approaching us vs. moving away. In this case, the rate of approach is 24 miles-per-second.
