Behold a 3D map of of the universe, showing all galaxies out to 300 million light years

Brent Tully, a cosmologist at the University of Hawaii's Institute for Astronomy has mapped the universe in detail out to a distance of about 100 million light years. To put that in more human terms: Columbus's maps of the New World described a land 3,000 miles from home, but Tully's map extends 6,000,000,000,000,000,000 miles out. No wonder he is often referred to as a cosmic cartographer. By filling in the details, Tully has made it possible to discern the true structure of the universe: clusters of galaxies arranged into enormous filaments, bound together by invisible strands of dark matter, and tremendous lonely voids where galaxies are sparse.
