While you’re reading this, stars above your head explode, planets burn, and black holes curl strings of light. Take a look at these transformations in Universe Sandbox 2! Toggle the Solar System: freeze Earth, toss Neptune in Uranus, or untie Jupiter’s rings and let them explode the neighbors. But the Sun is less than a crumble compared to the Galaxy.

Fly towards vaguely familiar nebulas and watch other stars live moderately and die in splendor. And build systems with real physics behavior!
