Laniakea: Our home supercluster

                                                 




Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe.

But scientists have struggled to define exactly where one supercluster ends and another begins.

Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space.
Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian.


This map of the universe spans more than 500 million light-years and contains more than 100,000 galaxies.
