Terzan 5 star cluster may be a fossil relic from the Milky Way's formation
By
Keith Cooper
Summary
Terzan 5, a massive globular cluster of stars, may be a fossil fragment leftover from the formation of the Milky Way's bulge. Unlike most globular clusters which contain only one generation of stars, Terzan 5 contains four distinct generations of stars, suggesting it is a surviving relic from the early formation of our galaxy. This discovery provides direct evidence that could help explain how galactic bulges form.

Terzan 5 could be a clump of our galaxy's central bulge that hasn't been smoothed out into the mix, and has instead survived as a fossil relic leftover from the birth of the Milky Way galaxy.
Four generations of stars have been identified in Terzan 5, as opposed to just one generation in most globular clusters.
