Imagine a map so big that it makes entire galaxies look like floating dust particles? That's what you can expect from this newly released clip featuring an animated flight through the universe. Hailed as the largest-ever 3D map of the universe, it even includes galaxies that date back seven billion years (around 400,000 galaxies or so):
To achieve this, an association of two dozen universities from around the world called Sloan Digital Sky Survey III used a massive wide-angle optical telescope at New Mexico’s Apache Point Observatory to record the cosmos bit by bit, which were then used to piece together an unprecedented look at our universe. And just in case you still can't visualize how big this thing really is, each of these galaxy is hundreds of thousands of light years side-to-side.
