Enormous Galaxy Clusters Found to be 1.3 Billion Light-Years Wide, Deemed to be The Largest Known Structure In a monumental discovery, astronomers identified the largest known structure in the universe,

The cosmic superstructure Quipu is more than 13,000 times the length of the Milky Way, and its mass is 200 quadrillion times that of the sun, according to preliminary research

Mapping the distribution of matter in the universe is an important quest for cosmology and astrophysics. There is a battle going on between the universe's accelerated expansion and gravity trying to keep things all together.

Quipu, named after the Incan system of knotted cords used for recording information, spans an astonishing 1.3 billion light-years-a distance over 13,000 times the length of the Milky Way.
