Odd Radio Circles (ORCs) are mysterious astronomical objects discovered in 2019, visible only in radio wavelengths. They are hypothesized to originate from galaxy mergers or star formation shockwaves, emitting synchrotron radiation. Alternative theories suggest they could be radio jets or even wormholes. Further research is needed to understand their true nature.
