Globular Star Cluster Messier 54: Close-up View | ESO
This video gives a close-up view of an image from the VLT Survey Telescope at the European Southern Observatory’s Paranal Observatory in northern Chile showing the globular cluster Messier 54. This cluster looks very similar to many others, but it has a secret. Messier 54 does not belong to the Milky Way, but actually is part of a small satellite galaxy, the Sagittarius Dwarf Galaxy. This unusual parentage has allowed astronomers to use the Very Large Telescope (VLT) to test whether unexpectedly low levels of the element lithium are also found in stars outside the Milky Way.
