X-ray telescope has taken the most detailed map of black holes

German-made space telescope has created the most detailed map of black holes and neutron stars

The universe. Scientists reported that they were able to detect 3 million new objects in less than two years.

An observatory called eROSITA was launched in2019 - it became the first space-based X-ray telescope capable of capturing the entire sky. It is the main instrument aboard the Russian-German spacecraft Spektr-Roentgen-Gamma, which sits in an area known as the Lagrange point, one of five stable points around the Sun-Earth system where the gravitational forces of the two bodies are in equilibrium. From this vantage point, eROSITA can clearly observe the universe, which the device photographs with powerful X-ray instruments.

eROSITA started taking first pictures in October 2019of the year. Since then, he has completed three all-sky surveys, creating sky maps showing the distribution of X-ray sources in the universe.

This data has not yet been published for a widescientific community, but the researchers note that the catalogs contain information about 3 million sources of X-ray radiation - black holes, neutron stars and galaxy clusters. About 77% of these sources are distant black holes in other galaxies, 20% are neutron stars, stars and black holes in the Milky Way. The remaining 3% are galaxy clusters.

Earlier observations of the telescope have already led tointeresting discoveries, including the detection of giant X-ray bubbles emanating from the center of the Milky Way. Mission senior scientist Andrea Merloni noted that with the first public scientific release, eROSITA could shed light on some long-standing cosmological mysteries, including the distribution of dark energy in the universe.
