Astronomers have spotted the largest known structure in the universe - a group of quasars (Quasi-Stellar Radio Objects) so big that it would take 4 billion years to cross it while moving at the speed of light. The mind-boggling scale  challenges Einstein's Cosmological Principle that the universe looks the same from every point of view.

 


 

 

Quasars are thought to be the brightest objects in the universe, with light coming from the nuclei of galaxies belonging to early universe and visible from billion light years away.

 

This large quasar group has a dimension of 500 megaparsecs, each megaparsec measuring 3.3 million light-years.The size is 1,600 times larger than the distance from Earth's Milky Way to the nearest galaxy, the Andromeda.
