Starchitect is a free astronomy education game about stellar and planetary evolution. Here you can create different types of stars, then add planets, and even try for life. All of this happens at a million years a minute (for reference, that would make our solar system about three days old).

As much as possible Starchitect is based on our best understanding of astronomy, astrophysics, and astrobiology. The evolution of the stars, the incidence of supernovas, etc., are all based on current science.

See what you can do... make a star, add some planets, and see if you can get life going.

Good luck!


Things To Know

Take your time: Starchitect runs at one million years to a minute. At that rate it can take days to establish life on a planet.

Watch your energy: Most actions require energy. Energy is limited, but it will restore over time.

We're cool with time travel. If you need to go back in time, just click in the timeline. But remember that you might undo some of your planets.

Note: Starchitect does not currently run on phones and tablets. Sorry about that.
