Astronomers at a British university are challenging our understanding of the universe with the discovery of a massive ring of galaxies that is 1.3 billion light years in diameter. If we could see it in the night sky, it would be 15 times the size of the Moon. This discovery contradicts one of the central principles of astronomy, which states that entities of matter much larger than galaxies should not form in space. The structure discovered by PhD student Alexia Lopez has already been named “The Big Ring” and “The Giant Arc.” It is located over nine billion light-years away from Earth and was presented at the 243rd Annual Meeting of the American Astronomical Society (AAS) held in early January in New Orleans. Lopez believes that these structures may be remnants of the early universe.
