Astronomers See ‘Cosmic Ring of Fire’, 11 Billion Years Ago

Astronomers have captured an image of a super-rare type of galaxy – described as a “cosmic ring of fire” – as it existed 11 billion years ago. The galaxy, which has roughly the mass of the Milky Way, is circular with a hole in the middle. Its discovery is set to shake up theories about the earliest formation of galactic structures and how they evolve.
