If you've ever wondered how the universe looked a hundred, a thousand or even a million years ago, the Illustris simulation program gives space fanatics an in-depth look inside a virtual digitized depiction of the universe.
The Illustris simulation took five long years to create and it shows an extensive visual representation of the evolution of the universe. Using colorful graphics, the Illustris simulation shows how stars, cloud nebulae and galaxies were formed from the start of the Big Bang 12 million years ago. The virtual space program also takes the time to show the universe on a wide, encompassing scale as well as on a small scale -- down to the very last star. One thing watching the Illustris simulation will surely do is remind you how big our universe is.
