Map of the universe has been redrawn by scientists. They have used new tools for defining galaxies. The supercluster in the galaxies, that has the Milky Way, is entitled to ‘Laniakea’. It means ‘immense heaven’. The word is Hawaiian.
Defining the areas of universe is not an easy task. The supercluster, now named Laniakea, is said to be 500 million light years in diameter. It contains 100,000 galaxies. These galaxies if weighed together, carries 100 million billion times of our sun’s mass.
