Scientists presented the results of observing space using the eROSITA X-ray space telescope.
On February 1, astronomers unveiled the eRASS1 catalogue, the largest ever catalog of the most powerful energy sources in the Universe, such as exploding massive stars and active galactic nuclei that power black holes. Also presented here, Space writes, are the largest known structures in the universe – filaments of the cosmic network of hot gas connecting galaxies in galaxy clusters.

The eROSITA X-ray space telescope, created by German scientists, began its work in 2019, and now astronomers have published the first results of observing the Universe in X-rays. The telescope has discovered nearly 1 million high-energy sources, including more than 700,000 supermassive black holes.
Important
It turned out that in just the first six months of operation, eROSITA had discovered more high-energy X-ray sources than had been discovered in 60 years. The results of observing the universe in X-rays will help answer some of the most important questions in cosmology. For example, how did the Universe develop and why does the fabric of space expand with acceleration?
Observation results show that the telescope discovered a supercluster of more than 1,000 galaxies, two quasi-periodically exploding black holes, and determined the effect of X-ray emission from stars on the retention of water and atmosphere of planets orbiting them.
The eRASS1 catalog included the results of observations carried out with the eROSITA telescope from December 2019 to June 2020. During this period, the space telescope detected approximately 170 million individual particles, or photons, of X-ray light.
Study of these particles led to the discovery of 900,000 X-ray sources; 700,000 of these fuel supermassive black holes that form bright quasars in active galactic nuclei. The light from quasars is so strong that it often blocks the light of all stars in its galaxy.
The ERASS1 catalog also includes 180,000 X-ray emitting stars in the Milky Way, 12,000 galaxy clusters, and even exotic classes of X-ray sources such as binary stars, supernova remnants, pulsars, and other objects.
The data feed is also impressive in that it reveals the precise locations from which individual X-ray particles arrived, as well as the arrival time and energy of these photons.
As I already wrote FocusThe project, one of the most expensive projects of the European Space Agency, has been officially given the green light. The truth is that it has become known that a new detector will eventually be implemented that will detect the phenomenon predicted by Einstein.
Moreover Focus He wrote that astronomers have discovered a galaxy that emits 10 times less light than the faintest galaxies. The new discovery could change astronomers’ understanding of the nature of dark matter.
