astronomical X-ray sources

This field of view also contains hundreds of astronomical X-ray sources, some of them supermassive black holes.

To conduct an all-sky survey which will be more sensitive than any previous one, and will add significantly to scientific knowledge of astronomical X-ray sources.

The origin of all observed astronomical X-ray sources is in, near to, or associated with a coronal cloud or gas at coronal cloud temperatures for however long or brief a period.

In X-ray wavelengths, many scientists are investigating the scattering of X-rays by interstellar dust, and some have suggested that astronomical X-ray sources would possess diffuse haloes, due to the dust.

As with the astronomical X-ray sources, striving to understand the generation of X-rays by the apparent source helps to understand the Sun, the universe as a whole, and how these affect us on Earth.

The Rossi X-ray Timing Explorer (RXTE) is a satellite that observes the time structure of astronomical X-ray sources, named after Bruno Rossi.
