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 (AGN) to galactic objects such as supernova remnants, stars, and binary stars containing a white dwarf (cataclysmic variable stars and. Therefore stars at the hot and at the cool end of the magnetic activity range are intrinsically X-ray fainter and correspondingly their X-ray horizon will be closer. In the regime of intermediate mass stars, the young HAeBe stars (Stelzer et al., ) and the magnetic ApBp stars (Robrade & Schmitt, ) are prime targets for X-ray : J. Robrade.   Stars range in size from neutron stars, which can be only 12 miles (20 kilometers) wide, to supergiants roughly 1, times the diameter of the sun. The size of a star affects its brightness. The life and death of stars in Scorpius. The youngest stars are found in open clusters, while the oldest populate globular clusters. Only its emission of X-rays and gamma rays gives it away.

The Orion Nebula (also known as Mess M42, or NGC ) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1, ± 20 light years and is the closest region of massive star formation to ce: 1,±20 ly ( pc).

The history of X-ray astronomy begins in the s, with interest in short wave communications for the U.S. was soon followed by extensive study of the earth's , interest in the detection of X-ray and ultraviolet (UV) radiation at high altitudes inspired researchers to launch Goddard's rockets into the upper atmosphere to support theoretical studies and data gathering. Extreme Stars Figure Stars seemingly pile upon stars in this photograph of the Milky Way in Cygnus. Seen from a great distance, our Sun would be just one of them, an ordinary star in the middle of an immense range of stellar properties. [From the Atlas of the Milky Way, F. E. Ross and M. R.
