Astronomers Investigating ORCs

Astronomers are spotting strange new signals, with their radio telescopes. They’ve found 4 circular objects, that are brighter at the edges. Astrophysicist Ray Norris, has nicknamed them ORCs, which is short for Odd Radio Circles. They could be star-forming galaxies or planetary nebulas, but it’s more likely they’re something entirely new. It’s a space mystery!
