A team of researchers led by University of Hawaii astronomer Brent Tully has mapped the structure of the universe at a vast scale. In particular, they have mapped the shape of the Local Void, an empty expanse of intergalactic space hundreds of millions of light years across; the Milky Way is found at the edge of the Void. From the University of Hawaii\u2019s Institute for Astronomy press release<\/a>:<\/p>\n

Now, Tully and his team have measured the motions of 18,000 galaxies in the Cosmicflows-3 compendium of galaxy distances, constructing a cosmographic map that highlights the boundary between the collection of matter and the absence of matter that defines the edge of the Local Void. They used the same technique in 2014 to identify the full extent of our home supercluster of over one hundred thousand galaxies, giving it the name Laniakea, meaning “immense heaven” in Hawaiian.<\/p><\/blockquote>\n
