GCl 38

GCl 38 is a globular cluster located in theconstellation Hercules.It was discovered in 1958 by Sidney van den Bergh and Halton Arp during inspection of the photographic plates from the Palomar Sky Survey.This is a round, diffuse cluster located in the outerhalo of the Milky Way galaxy. It is about 3–4 billion years younger than a typical galactic cluster. Because of the cluster's location on the outer fringes of the Milky Way, it was used as a test case for modified newtonian dynamics (MOND). This is an alternative hypothesis to explain the galactic rotation problem.
