A new map of the entire sky, as seen in X-rays, looks deeper into space than any other of its kind.

The map, released June 19, is based on data from the first full scan of the sky made by the eROSITA X-ray telescope onboard the Russian-German SRG spacecraft, which launched in July 2019.

The six-month, all-sky survey, which began in December and wrapped up in June, is only the first of eight total sky surveys that eROSITA will perform over the next few years. But this sweep alone cataloged some 1.1 million X-ray sources across the cosmos — just about doubling the number of known X-ray emitters in the universe.

In this map of X-rays emitted by celestial objects across the sky, X-rays are color-coded by energy: Blue signifies the highest energies, followed by green, yellow and red.

The red foreground glow comes from hot gas near the solar system, whereas the Milky Way plane appears blue, because gas and dust in the disk absorb all but the most energetic X-rays.
