A real 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 astronomers use to trace cluster evolution.... Read More

All the stars in this simulated model of the globular star cluster Omega Centauri 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.... Read More
