Berlin / Moscow: Russian and German experts have released the first X-ray image of the universe obtained from an X-ray space telescope called E-Rosetta. In this one image, more than a million astronomical objects can be seen emitting X-rays.
EROSITA stands for Extended Roentgen Survey with an Imaging Telescope Array, the most important part of the Spectrum Roentgen Gamma (SRG) to be sent into space in 2019. Is. Although the purpose of this space observatory is to conduct research on “dark energy”, for this purpose it has to exclusively include X-rays emitted from various astronomical objects.
It should be noted that X-rays are actually electromagnetic (electromagnetic) rays, but firstly their energy is very high and secondly that the human eye can not see them. The sun emits X-rays, along with many other rays, which the protective shell of the earth’s atmosphere prevents from reaching us and thus we are protected from the lethality of these rays.
The use of X-rays in medical diagnosis has been around for over a century and is commonplace today. However, too many X-rays can result in cancer.
In addition to stars, when black holes “consume” matter scattered around them, they emit even more powerful X-rays, which are called the “last scream” of matter falling into the black hole.
This image shows many of the same stars and black holes that have been given different colors to make them visible to the human eye.
Remember that the e-Rosetta / RSG project covers a period of four years and will be completed in 2023. Its purpose is not only to identify supermassive black holes at the centers of galaxies, but also to take a closer look at the thousands of galaxy clusters that are considered to be the weakest force in the universe, gravity. “It’s very tightly tied together.
By learning in detail about the structure and motion of galaxy clusters, we will be able to tell us something about “dark energy”, also known as a “mysterious” energy that is cosmic. This is causing an increase in the speed of spread.
It will be interesting to read that in just a few months, E Rosetta has observed at least twice as many observations of the universe as X-rays have made in the last 60 years.
However, the work of E-Rosetta has just begun and it is expected that soon we will see even more beautiful and detailed X-ray images of the universe.
