It’s a truism among oceanographers that there is more accurate mapping of the surface of the moon and Mars than of the deep-ocean floor. That’s especially true for the Bismarck Sea, a relatively deep body of water north of Papua New Guinea.

Astronomers have identified a possible new member of one of astronomy’s strangest classes of objects: Odd radio circles (ORCs), enormous ring-like structures visible only at radio wavelengths.

The paper was posted to the arXiv preprint server on May 6.
