For the first time, unusual circles appeared in the field of view of the Australian Radio Telescope Complex ASKAP At the end of 2019 when data were collected to create an evolutionary map of the universe, astronomers called the three cosmic smoke rings “strange radio circuits” or “orcs.”“.
In the beginning, scientists misunderstood objects because of a program error, and other radio telescopes also spotted the ORC.“.
The researchers said they had never seen anything like this before. The orc can only be seen in radio waves, and it is impossible to see mysterious objects in the X-ray, optical or infrared ranges..
In total, several thousand rings have been discovered in the sky. Until now, scientists do not know the answer to the question of what these mysterious circles are. According to astronomers, UFs are not supernova remnants, and they cannot be star-forming regions, nor do they resemble Einstein’s rings. The size of the circles is also unknown.
