IC 4499

Globular cluster IC 4499 taken by Hubble Space Telescope.

IC 4499 is a loose globular cluster in the constellation Apus. It is located in the medium-far galactic halo.[1] Its apparent magnitude is 10.6,[2] and it is unusual because it appears to be 3-4 billion years younger than most other globular clusters in the Milky Way, as determined by its metallicity.[1]
