The image of the extragalactic sky about one square degree in area shows dozens of X-Ray sources, mainly active galactic cores and quasars. The image is shown in the energy range 0.5-2 keV with the exposure duration about 2000 seconds. The data was received by the Russian and German consortiums of the eROSITA telescope.

The Spektr-RG space observatory was injected into orbit by the Proton-M carrier rocket with the DM-03 booster on July 13, 2019. The observatory includes two unique X-Ray mirror telescopes ART-XC and eROSITA working on oblique incidence principle. The Russian ART-XC telescope has been watching the Milky Way galaxy center.

Now the spacecraft is 1,614 million kilometers away from Earth continuing its journey towards the L2 Sun – Earth system libration point with the arrival to the working orbit expected in the end of October 2019.
