Messier 54 is a globular cluster located in constellation Sagittarius. It has been assumed that the cluster’s distance is 50’000 light-years. Recently (1994) it was discovered that this cluster doesn’t belong to Milky Way galaxy, but it’s a part of Dwarf elliptic galaxy in Sagittarius and it is approximately 86’400 light-year from Earth. This means M54 is first discovered globular cluster outside of our galaxy.
