German technology and science play a decisive role on board.
Scientists are enthusiastic about the initial results.
With the help of the XMM, scientists observe the X-rays emitted by a wide variety of objects, such as comets, neutron stars, supernovae remnants, galaxies, quasars and clusters of galaxies. One example are the clusters of galaxies, the largest coherent structures in the universe. While optical telescopes show only the individual galaxies, X-ray telescopes also reveal the hot gas that concentrates at the core of the galaxy cluster due to gravity. XMM thus makes it possible to explore the gravitational field, estimate the effects of dark matter and calculate the temperature profile of the gas. It is located at the center of the Virgo galaxy cluster and is presumed to contain a black hole that emits a so-called jet, or energetic ray of matter.
