The observatory, we recall, went into space last summer. It carries the X-ray telescopes ART-XC and eRosita, which were created in Russia and Germany respectively.

«Spectrum-WP» now performs the main scientific program, which is designed for four years: it provides eight complete reviews of the celestial sphere. The first of these reviews is now three-quarters complete.

For almost five months the ART-XC telescope of the observatory "Spectrum-WP" has been observing in hard X-rays, examining every day a new large ring of one degree wide in the sky. On May 4, 2020 the next sign mark was passed - three quarters of the sky have been inspected», - informs IKI RAN.

The following image shows selected X-ray sources of galactic and extragalactic origin, with a total of several hundred of them on a map of three quarters of the sky. Specialists note an increased concentration of sources in the central region and plane of the galaxy, as well as in the poles of the ecliptic.

It is expected that the next month the ART-XC Telescope will complete its first complete review of the celestial sphere.
