caption_attribution_description: English: This Chandra image shows two vast cavities - each 600,000 light years in diameter - in the hot, X-ray emitting gas that pervades the galaxy cluster MS 0735.6+7421 (MS 0735 for short). Although the cavities contain very little hot gas, they are filled with a two-sided, elongated, magnetized bubble of extremely high-energy electrons that emit radio waves. The cavities appear on opposite sides of a large galaxy at the center of the cluster, which indicates that a gigantic eruption produced by the galaxy's supermassive black hole created the structures. The magnitude of the eruption suggests that as a large amount of gas swirled rapidly toward the central black hole, it generated intense electromagnetic fields that ejected a fraction of the gas in the form of powerful jets of high-energy particles. As these jets blasted through the galaxy into the surrounding multimillion degree intergalactic gas, they pushed the hot gas aside to create the cavities. The mass of the displaced gas equals about a trillion Suns, more than the mass of all the stars in the Milky Way.
context_page_description: Astrophysical X-ray sources are astronomical objects with physical properties which result in the emission of X-rays.
  There are a number of types of astrophysical objects which emit X-rays, from galaxy clusters, through black holes in active galactic nuclei to galactic objects such as supernova remnants, stars, and binary stars containing a white dwarf, neutron star or black hole. Some solar system bodies emit X-rays, the most notable being the Moon, although most of the X-ray brightness of the Moon arises from reflected solar X-rays. A combination of many unresolved X-ray sources is thought to produce the observed X-ray background. The X-ray continuum can arise from bremsstrahlung, either magnetic or ordinary Coulomb, black-body radiation, synchrotron radiation, inverse Compton scattering of lower-energy photons by relativistic electrons, knock-on collisions of fast protons with atomic electrons, and atomic recombination, with or without additional electron transitions.
  Furthermore, celestial entities in space are discussed as celestial X-ray sources.
