Largest 3D Map of the Universe Contains a Million Galaxies
70 billion cubic light years are represented on the new map
The largest 3D map yet of the universe's huge galaxies and bright black holes may serve as a springboard toward solving some of astronomy's greatest mysteries, its creators say.
The map, which was released Wednesday (Aug. 8), uses new data to reveal the locations of more than a million galaxies over a total volume of 70 billion cubic light-years. (A light-year is the distance light travels in one year — about 6 trillion miles, or 10 trillion kilometers.)
