Space telescope to chart first map of the Universe in high-energy X-rays



This portrait of the sky at X-ray wavelengths reveals one million sources, including many distant galaxies with ‘active’ nuclei. It was created by the eROSITA telescope aboard SRG, a German-Russian mission that launched last year. The map also displays hot gas in the Milky Way and its surroundings.
