The movement of substances found in them exceeds the speed of light.
Astronomers from Kazan Federal University (KFU), together with scientists from the Space Research Institute of the Russian Academy of Sciences (IKI RAS), have discovered a new class of galaxies.
When studying the catalog of space objects, scientists discovered regarding 500 new galaxies that have unusual properties. The press service of universities also mentions that all these galaxies are charged with active nuclei.
The studied catalog consists of 173 thousand stars and was created using data provided by the eROSITA X-ray telescope. The device was launched into space back in 2019 by the Spektr-X-ray Gamma orbital observatory. The tasks of the observatory included: the study of new phenomena in space and the compilation of a new detailed map of the universe.
At the moment, astronomers plan to find out what caused the rapid movement of unusual space objects.
What is the difference between new galaxies?
First, celestial bodies with active nuclei move extremely fast. Studies have shown that their movement is anomalous.
“Visual inspection of these unusual space objects indicated their extended morphology, characteristic of extragalactic sources,” said Professor of the Department of Astronomy and Space Geodesy of the Institute of Physics of KFU Ilfan Bikmaev.
Secondly, as the expert notes, the discovered galaxies, more precisely, the moving substances in them, move tens or even hundreds of times faster than the rest of the substances discovered earlier and known to scientists for a long time. Amazingly, their movement exceeds the speed of light, and this is contrary to the laws of physics.
Already in the coming year, astronomers plan to do further study of galaxies. One of the most powerful space telescopes RTT-150 will help them in this.
