Best of AOP - Star Clusters


M107 is the last globular cluster in Messier's catalogue of 110 objects. Messier's catalogue originally included only 103 objects. Upon discovering notes from Messier suggesting that he did indeed know of several other deep sky nebulae, clusters and galaxies, astronomers added seven extra objects including the globular cluster M107. M107 lies about 21,000 lightyears away in the constellation Ophiuchus.
