Messier Ball Cluster 15

The term M15 stands for Messier 15. M15 was discovered in 1746 by Jean-Dominique Maraldi, an Italian astronomer who was hunting for comets. This spherical cluster is one of the densest ever found, with very hot blue stars and cooler orange stars becoming more concentrated towards their bright core. M15 is located in the constellation Pegasus 33,600 light years from Earth. Shining with a magnitude of 6.2, this cluster can be seen with a pair of binoculars. The best time to observe it is in October.

M15 is the first globular cluster known to host a planetary nebula (gas shell of a dying star). This nebula, Pease 1, was detected in 1928 by Francis G. Pease and is one of only four planetary nebulae known to exist in a globular cluster.

Messier Ball Cluster 2

The term M2 stands for Messier 2. The first spherical cluster to be added to the Messier catalogue, M2 is located about 37,000 light-years from Earth in the constellation Aquarius. A spherical cluster is a group of spherical stars bound together by their mutual gravitational attraction. M2 is over 150 light-years in diameter and is one of the largest clusters of its kind. It was discovered in 1746 by the French astronomer Jean-Dominique Maraldi while he was observing a comet.

This Hubble image of the M2 core was created using observations taken at both visible and infrared wavelengths. M2 contains more than 150,000 stars. Most of the cluster’s mass is concentrated at its center, with a stream of shimmering stars extending out into space. This cluster has an apparent magnitude of 6.3 and can be seen with the naked eye under ideal viewing conditions. The best time to observe M2 is during October.
