Located 20,000 light-years away in the Carina spiral arm of the Milky Way galaxy, contains a central cluster of huge, hot stars called NGC 3603. One of 1,100 open clusters discovered so far in our own galaxy, NGC 3603 contains thousands of stars all formed from the same molecular cloud. The stars contained in these massive clusters are all gravitationally bound to each other as the cluster orbits the center of the galaxy, just like us. Every now and then, these clusters will be disrupted by other clusters or large clouds of gas if they get close enough. This disruption very likely will send individual stars hurtling away through space.
