Scientists have officially given a name to the largest solar structure in the known universe. Astronomers have found the largest structure in the Universe so far, named Quipu. The object, called a superstructure, is more than 400 megaparsecs long. In fact, the superstructure is estimated to hold an almost inconceivable 200 quadrillion (that's 200 followed by 15 zeros) times the mass of the sun and is more than 1.3 billion light-years long, larger than the Milky Way.
