This week’s amazing galaxy is not a galaxy at all. It is, in fact, a globular cluster. Globular clusters are relatively tightly-packed groups of stars that orbit the cores of large galaxies. There are about 150 known globular clusters in our own galaxy. This image shows one known as Messier 2 (or simply M2).
