The mysteries of outer space offer a new phenomenon to the list… astronomers have documented something called ‘freak radio circles’ … and there’s a lot going on.
–
This ORC was first discovered by astronomers in 2020, using the Australian SKA Pathfinder telescope … operated by Australia’s national science agency, CSIRO.

The Commonwealth Scientific and Industrial Research Organization believes something like this took a billion years to reach its maximum size, and stretches about 16 times as massive as the Milky Way. It’s been extended past several galaxies.
–
The South African Radio Astronomy Observatory’s MeerKAT telescope was able to get an even better shot.
–
Researchers have several theories… be it the result of an explosion at the center of the galaxy, a jet propelling energetic particles, or the result of a starburst shock wave, caused by the creation of new stars.

Ray Norrisa professor at Western Sydney University and CSIRO, said, “We know ORC is a faint radio emission ring surrounding a galaxy with a very active black hole at its center, but we don’t yet know what causes it, or why it happens. very rare.”
–
So far, only 5 strange radio circles have been seen, all with telescopes observing through radio wavelengths. Visible light, infrared and X-ray telescopes have not yet documented ORC.
