Since Earth's atmosphere absorbs X-rays and prevents them from reaching the ground, X-ray telescopes must fly high above the planet in order to perform their job.
In comparison, previous X-ray telescopes were capable of focusing X-rays to five arc seconds.
The finding involves a new explanation for a set of results made with NASA's Chandra X-ray Observatory, ESA's XMM-Newton and Hitomi, a Japanese-led X-ray telescope. If confirmed with future observations, this may represent a major step forward in understanding the nature of the mysterious, invisible substance that makes up about 85% of matter in the universe.
Ping Zhou from the University of Nanjing in China used X-ray images from ESA's X-ray telescope XMM-Newton from 2008 and 2009 to discover a bright source south of the supernova remnant that was not visible in previous observations made from 2001 to 2007.
Hinode also carries an X-ray telescope that detects hot gases in the sun's corona.
With a planned launch date in the summer of 2006, the Solar-B satellite will use its 50cm-diameter optical telescope with a focal plane package, grazing-incidence soft X-ray telescope, and EUV imaging spectrometer to observe the solar atmosphere.
The quasar was detected by the ROSAT orbiting X-ray telescope operated by the Max-Planck Institute for Astrophysics in Garching, Germany.
Collins now has the responsibility of releasing a pounds 1billion X-ray telescope, which will spend five years looking at galaxies, quasars, and exploded stars.
Collins and her four-man crew are due to place the world's most powerful X-ray telescope into orbit.
The Space Research Group at The University of Birmingham designed and built the first pointed X-ray telescope to fly on the Space Shuttle.
