by Using the Australian Square Kilometre Array Pathfinder (ASKAP), astronomers have detected a new extragalactic odd radio circle (ORC).
The newfound radio source, designated ORC J0102–2450, has a diameter of nearly 1 million light years.
Odd radio circles (ORCs) are very large mysterious objects that are highly circular and bright along the edges at radio wavelengths.
Although ORCs are bright at radio wavelengths, they cannot be observed at visible, infrared or X-ray wavelengths.
So far, only few objects of this type have been identified, hence very little is known about their origin and nature.
