Astronomers spot unidentifiable ‘circular’ phenomena over Australia – New York Post
Australian astronomers have detected a series of inexplicable signals that they believe could be “a new class of astronomical object.”

Australian astronomers have detected a series of inexplicable signals that they believe could be “a new class of astronomical object.”
A team of international researchers at the Australian Square Kilometre Array Pathfinder (ASKAP), in the continent’s Western region, has dubbed the objects “odd radio circles,” or ORCs.
Led by astrophysicist Ray Norris of Western Sydney University, the scientists shared their findings on arXiv, an open-access scholarly articles archive, while their report awaits peer review for publication into the journal Nature Astronomy.
Their study describe four ORCs, which appear as glowing orbs, three of which have distinct, bright rings around the circular object and ruled out several possible explanations for their existence.
“Circular features are well-known in radio astronomical images, and usually represent a spherical object such as a supernova remnant, a planetary nebula, a circumstellar shell, or a face-on disc such as a protoplanetary disc or a star-forming galaxy,” they wrote in their report.
“They may also arise from imaging
