Star Cluster Palomar 2 Square ) The reduction of hazeGlobular clusters are relatively common in our sky, and generally look similar. However, this image, taken using the NASA ESA Hubble Space Telescope, shows a unique example of such a cluster Palomar 2. Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, a project that involved some of the most well
