TL;DR Summary

Astronomers using the Magellan Clay telescope have discovered that the globular cluster VVV CL002 is on a tight retrograde orbit and is falling towards the Milky Way's center. The cluster, located 23,800 light years away and discovered in 2011, has a high eccentricity orbit with perigalactocentric and apogalactocentric distances indicating it is well within the galactic bulge. The study, which also analyzed the cluster's chemical composition, suggests that VVV CL002 is an old cluster that was formed outside the central region and is now spiraling inward, likely to be destroyed in the future. Further observations could provide insights into the survival and migration of such clusters.
