22 Oct 2019 - eROSITA First Light: On 22 October 2019, the beautiful first X-ray images of the eROSITA telescope were presented to the public at the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching. After an extended commissioning phase, since October 13 all seven X-ray telescope modules with their custom-designed CCD cameras have been observing the sky simultaneously. The first combined X-ray images of our neighbouring galaxy, the Large Magellanic Cloud, and a pair of interacting clusters of galaxies at a distance of about 800 Million lightyears, show remarkable details and demonstrate the promise of the ambitious science programme planned with the space-borne telescope.
