Deep in outer space, astronomers have discovered another "odd radio circle" — the latest in a short list of mysterious rings that surround distant galaxies — and researchers say this one is particularly peculiar.

"Odd radio circles," or ORCs, are enormous and unexplained phenomena that can only be detected using radio telescopes . So far, just a handful have ever been identified.

Now, researchers at the University of Mumbai in India, with help from citizen scientists and the world's largest low-frequency radio telescope, have pinpointed "the most distant and the most powerful ORC known to date," according to the London-based Royal Astronomical Society .
