The Fornax Dwarf Galaxy

The Fornax dwarf galaxy, at a distance of only 460 light-years, is one of the Milky Way's nearest cosmic neighbors. This diminutive collection of stars actually boasts six globular clusters, large spherically shaped star clusters with hundreds of thousands of stars each. While these clusters appear very similar, in general, to the approximately 150 globular clusters found circling our galaxy, one of them, Fornax 4, inexplicably appears to be about 3 billion years younger than the others. Astronomers currently have no good explanation as why this would be the case. The Fornax dwarf galaxy is also designated PGC 10074/10093 and can only be seen from the southern hemisphere.
