Universe Reference Map
As far as we can see with our ever-improving telescopes, there are at least a hundred billion galaxies arrayed throughout the universe. Each, like the Milky Way, is an “island universe” containing billions of stars. This map uses graphic “leaps of scale” to show how our solar system fits within the vastness of the universe. The map also includes a universe timeline and a description of its evolution.
