Reflections on 20 Years of XMM Newton’s X ray Astronomy

Explore the scientific impact of ESA’s (the European Space Agency’s) XMM-Newton observatory for its 20th anniversary in space, as told by Ph.D. scientists whose work the mission enabled. XMM-Newton carries three X-ray telescopes with an unprecedentedly large collecting area, and an optical monitor — the first flown on an X-ray observatory. XMM-Newton’s telescopes and its ability to make long uninterrupted exposures provide highly sensitive observations of many targets, including active galaxies powered by supermassive black holes, star formation in galaxies, and X-ray flares from stars in our own Milky Way galaxy.
