New Radio Images of Bizarre “Odd Radio Circles” Which are Vastly Bigger Than the Milky Way
Known as Odd Radio Circles, or ORCs, they are roughly a million light-years across, which is about ten times wider than the Milky Way. Observations show that ORCs are centered around an elliptical galaxy, which suggests a galactic connection. It has been suggested that ORCs are formed by shock waves triggered by a powerful event such as a gamma-ray burst or fast radio burst, but given the size of ORCs, these events would need to have been triggered very far in the past.
