What is Laniakea Supercluster?
This galaxy is a super cluster of galaxies. It contains 100,000 galaxies, including the Milky Way. It is spread over 520 million light years. Includes Hydra, Cantaurus and southren supercluster.
The boundaries of these super clusters are very difficult to determine. However, the radio telescope determines to some extent the movement of the local group of galaxies inside it.
It was discovered in May 2014.
K. Yehuda Hoffman and Daniel Pomarède of the University of Paris jointly explained and praised it.
