Primary Science

The principal science objectives of the Chandra X-ray Observatory, or Chandra for short, are to determine the nature of celestial objects from normal stars to quasars, to understand the nature of physical processes which take place in and between astronomical objects, and to generally study the history and evolution of the universe. Observations are made of X-rays from high energy regions such as supernova remnants, X-ray pulsars, black holes, neutron stars, and hot galactic clusters.
