   Nov 17, 2014 · The most recent X-ray mission launched is NuSTAR, which is dedicated to observing hard X-rays (higher-energy X-rays than can be observed by other orbiting X-ray telescopes). NuSTAR will be seeking out black holes and other collapsed stars in our galaxy, mapping material in young supernova remnants, and studying relativistic jets in active ...

   How have X-ray astronomers revolutionized our view of the universe?

   • The astounding discoveries made by X-ray astronomers — such as neutron stars and black holes in binary systems, and hot gas filling the space within clusters of galaxies — have revolutionized our view of the Universe. On July 23, 1999, NASA’s Chandra X-ray Observatory, the most powerful X-ray telescope ever built, was launched into space.

   Why are X-ray telescopes used in astronomy?

   • (Credit: NASA) X-ray telescopes were first used for astronomy to observe the Sun, which was the only source in the sky bright enough in X-rays for those early telescopes to detect. Because the Sun is so bright in X-rays, early X-ray telescopes could use a small focusing element and the X-rays would be detected with photographic film.

   How X-ray astronomy has changed the world?

   • The two major developments influenced by X-ray astronomy are the use of sensitive detectors to provide low dose but high-resolution images, and the linkage with digitizing and image processing systems. Many diagnostic procedures, such as mammographies and osteoporosis scans, require multiple exposures.

   • Because the Sun is so bright in X-rays, early X-ray telescopes could use a small focusing element and the X-rays would be detected with photographic film. The first X-ray picture of the Sun from a rocket-borne telescope was taken by John V. Lindsay of the NASA Goddard Space Flight Center and collaborators in 1963.
