Omega Centauri: Delving into an Archeological Fossil of the Universe

Using Hubble to Chart the Future Motions of Stars Within a Cluster

The multicolor snapshot, at top, taken with Wide Field Camera 3 aboard NASA's Hubble Space Telescope, captures the central region of the giant globular cluster Omega Centauri. All the stars in the image are moving in random directions, like a swarm of bees. Astronomers used...

Omega Centauri Observation Zoom Sequence and Future Star Motions

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...

Omega Centauri Model Zoom Sequence and Future Star Motions

This is a zoom into a simulated model of the globular star cluster Omega Centauri. All 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...

Constructing the Hertzsprung-Russell Diagram for Globular Star Cluster

A Hubble Space Telescope color image of the core of the globular star cluster Omega Centauri is used to construct a Hertzsprung-Russell diagram of the stellar populations in the cluster. When stars are sorted by brightness and color they can be used to create a graph that...
