M 28 - Globular Cluster in the constellation Sagittarius

Messier 28 is much smaller than the neighboring globular cluster Messier 22 and is the first globular cluster in which a millisecond pulsar was discovered in 1986. In the course of time, at least 11 more pulsars were discovered in the neighborhood, making M28 the cluster with the third largest population of millisecond pulsars.
