Astronomers spot biggest structure in the universe
Discussion
Astronomers on Friday said they had observed the largest structure yet seen in the cosmos, a cluster of galaxies from the early Universe that spans an astonishing four billion light years.
The sprawling structure is known as a large quasar group (LQG), in which quasars — the nuclei of ancient galaxies, powered by supermassive black holes — clump together.
The discovery in the deep Universe was made by a team led by Roger Clowes at the Jeremiah Horrocks Institute at Britain’s University of Central Lancashire.
It would take a spaceship travelling at the speed of light four thousand million years to get from one end of the cluster to the other.
