View/Listen
In its first decade of exploration, Chandra has expanded our view of the universe with its unrivaled ability to create high-resolution X-ray images of cosmic phenomena: X-ray sources produced by matter circling only a few miles from a black hole, whirling, super-dense neutron stars expelling fingers and rings of extremely high energy particles, a look at the insides of an exploded star, and clouds of hot gas in galaxy clusters millions of light years across. None of this could be observed without an X-ray telescope.
