Researchers have sighted only a handful of these odd radio circles, and are trying to pin down what causes them
Astronomers have captured a close-up image of a rare and mysterious space object, prompting a renewed push to discover its origin. Odd radio circles are gigantic rings of radio waves. Only five have ever been sighted, and never in such spectacular detail.
“This discovery will start new scientific research among astronomers,” says Alice Pasetto, a radio astronomer at the National Autonomous University of Mexico in Mexico City. The first three ORCs, including ORC1, were discovered using the Australian Square Kilometre Array Pathfinder telescope in 2019. A fourth was identified in archival data from India’s Giant MetreWave Radio Telescope in 2013, and a fifth was discovered by Koribalski in newer ASKAP data last year. Most of the ORCs have a galaxy at their centre, which astronomers suggest might have something to do with their creation.
The second theory is that they result from the activities of an active galactic nucleus, with radio jets spewing particles to create the ORC’s shape. The third theory is that ORCs are shells caused by starbursts in the centre of their galaxies. “Like a detective, we’re gathering more and more clues as to what this object possibly could be,” says Koribalski.
