This movie sequence begins with a ground-based image of the giant globular star cluster Omega Centauri and zooms very tightly in to a Hubble Space Telescope image of the central region of the cluster. In a simulation based on Hubble data, the stars appear to be moving in random directions, like a swarm of bees. Astronomers used Hubble's exquisite resolving power to measure positions for stars in 2002 and 2006. From these measurements, they can predict the stars' future movement, shown here for the next 10,000 years.
