Accidental Discovery: Massive Billion Light-Year Galaxy Bubble Unveiled
Scientists mapping a web of galaxies have accidentally discovered a vast bubble named Hoʻoleilana, located 820 million light-years from Earth. This structure, larger than the previously discovered Laniākea supercluster, contains previously known superclusters such as the Coma Cluster and the Sloan Great Wall. The diameter of Hoʻoleilana, measuring one billion light-years, exceeds theoretical expectations and is thought to be the result of ripples in the early universe known as Baryon Acoustic Oscillations.
