Discovery of gargantuan ring structure ‘challenges understanding of universe’
Scientists have discovered a gargantuan ring-shaped structure – about 1.3 billion light-years in diameter – that they say is so big it challenges our understanding of the universe.
Dubbed the Big Ring, this ultra-large structure – with a circumference of about four billion light-years – was observed in the remote universe, around 9.2 billion light-years away.
