The X-ray telescope eROSITA only collects data for about six months, but was able to make discoveries more than twice that of other telescopes to X-rays over the last 60 years. The spectacular map includes an imaging detailed hot gas of the milky Way, nebulas, black holes, binary stars and other objects cosmic in the universe. It is four times the depth of the spatial maps previous.
Astronomers germans and russians worked together to begin the mission to the telescope last year. “We have built eROSITA to transform the way we see the sky in X-rays and to explore the mysteries of the cosmology, and black holes,” said Peter Predehl, principal investigator of the X-ray telescope at the Max Planck Institute for extraterrestrial physics in Germany (MPE).
“This image all-sky completely changes the way we see the universe of energy,” said Predehl in a recent press release. The images are unique as eROSITA traced the thermal energy of the sky. The galaxies appear in clusters, resembling halos bright and vivid due to the concentrations of dark matter that confine the hot gases.
Nearly 80% of the image is made up of supermassive black holes, our active galactic nuclei, which consume the material of dark space in the middle of galaxies. While the million space objects emit X-rays, called X-ray sources, the team has had to sort approximately 165 gigabytes of data of the seven cameras of the telescope to assemble
Within the milky Way, eROSITA has captured the old white dwarfs, remnants of supernova, stars hot corona and active galaxies as the clouds of the magellanic. Mara Salvato, a senior scientist of the MEP, said that they were waiting eagerly for the complete map of the sky eROSITA. Previously, telescopes have measured the sky at other wavelengths, and the new x-ray images may correspond to these findings. Predehl describes the astonishing images such as a “wealth of detail”.
More surveys are needed to identify the sources of X-rays so that astronomers can better understand their nature. Rare phenomena have also been captured: stars swallowed by black holes, merging neutron stars, and records thermal compact objects, that eROSITA has detected as ” explosions of unexpected X-ray “. “We need to immediately alert the ground-based telescopes to understand the product,” said Salvato.

The Russian scientist Rashid Sunyaev has said that their second survey will soon begin up to the end of the year. The team plans to create seven cards, similar to the course of the 3.5 years. “Their sensitivity combined will be five times better and will be used by astrophysicists and cosmologists for decades,” said Sunyaev.
Kirpal Nandra, head of the group of high-energy astrophysics at MPE, said that the work done by eROSITA had just revolutionized the astronomy of the x-rays. The team anticipates many more in the near future.
“This combination of the surface of the sky and the depth is transformative. We sample already a volume cosmological of the universe hot a lot bigger than it was previously possible. Over the next few years, we will be able to probe even further, where the first cosmic structures giant, supermassive black holes were formed.
