Save your favorite universes and change them later. Design everything from simple solar systems to massive galaxies. Watch as the celestial bodies orbit each other and collide in fiery explosions.
This older version of Universe Sandbox looks a little plain, but there's still plenty of educational space exploration to be had here. Space Sandbox allows you to create your own universe populated with comets, planets, moons, gas giants, stars, and even black holes. It's hugely improved in every area - graphics, physics, climate simulation and more - and can be yours for $24.99. Or, if you're really enthusiastic about the idea, you might prefer Universal Sandbox 2. But Universal Sandbox Premium ($9.95) removes that restriction, and allows you to create simulations as well as open them. (That's an hour of manipulating the simulations - you can browse them in a basic way forever.).
You only get one hour of playing around like this in the free version, unfortunately, so use it wisely. Maybe explode something, and watch how the orbits change. The program has a lengthy list of other simulations to explore, from relatively local (Saturn and its rings, various planets and their moons), to very distant (distant stars or entire galaxies) and historic (Pioneer, Voyager, Ulysses and other spacecraft as they fly past planets).īest of all, you can play around with any of this just to see what happens. That's good, but you're not restricted to the Solar System. It's easy to zoom in and out, or click and drag to move your viewpoint in 3D space. Open the "Solar System" simulation, for instance, and you'll see an animated view of our solar system showing all the planets, the moons and their actual orbits.Ĭlicking near an interesting celestial body displays details like its velocity, mass, diameter, density and more.
The program works well as an educational tool. Universe Sandbox Legacy is a physics-based space simulator with some unusual fun extras.
