An image of a peculiar globular cluster, M54, has been uploaded

Hi all,

An image of Messier 54, a special globular cluster, has been uploaded. This (visually pretty “normal”) cluster is located at the center of the Sagittarius Dwarf Galaxy, a Milky Way satellite, and has several curiosities in its structure. You can find it all at:

Messier 54. NGC 6715

Enjoy,
