Scientists have found a new and bigger revelation about our Milky Way galaxy. According to a new finding, the Milky Way galaxy is part of a much vaster and giant network of galaxies than it was previously thought.
Our galaxy flows along a stream of galaxies, forming a huge galactic network, on the fringes of a newly discovered collection of galaxy clusters, better known as a supercluster.
The newly identified collection of galaxy clusters has been named Laniakea, which means “heaven immeasurable” in Hawaiian.
Scientists say this gigantic supercluster is extraordinarily massive. Its massiveness can be easily understand with its mass that resembles the mass of 100 million billion suns within a region which spans about 520 million light-years.
The finding has been made by the astrophysicist R Brent Tully and his colleagues at the University of Hawaii in Honolulu.
The team of scientists sifted through data that describes the velocities and positions of more than 8,000 galaxies in the universe in order to find out fresh reports about the location of our Milky Way galaxy in the space.
After accounting for the movement triggered by the universe’s expansion, the team of scientists developed a three-dimensional view illustrating how gravity molds the cosmic neighborhood of a galaxy.
The new map exposes about the boundaries of Laniakea and weblike framework.
In the map, the Milky Way is seen lying along one of the lines of that network in a tributary feeding one of many rivers of galaxies.
Scientists explain those galactic streams converge in a gravitational valley that is approximately 200 million light years away near two massive clusters of galaxy, namely Centaurus and Norma.
According to the scientists, the finding of the study showed that their combined gravity is likely pulling other galaxies and clusters, including our Milky Way, within Laniakea.
The new map was published in the journal Nature on Thursday (September 4).
