## Features

- **3D universe exploration**: Fly from Earth through the Solar System, Milky Way, Local Group and cosmic microwave background.
- **Narrated universe journey**: Take a continuous zoom from Earth to the edge of the observable universe, with each stage shown at its real scale.
- **Planet Hunter**: Search real NASA TESS light curves for transit dips, rule out false alarms and view the result in 3D.
- **Exoplanet and Milky Way views**: See the Milky Way from outside and visit planetary systems placed at their measured distances.
- **Gravitational-wave sounds**: Play real LIGO detector data as sound and watch the signal rise into its final chirp.
- **Galaxy collision simulations**: Run gravity simulations of galaxy encounters, change the speed, add a black hole and observe tidal tails.

## FAQ

### Is Space Simulator free?

Yes. The homepage describes Space Simulator as free.

### Does it require an installation?

No installation is stated. It runs in a web browser.

### What can be explored?

The Solar System, the Milky Way, planetary systems around other stars, the observable universe and galaxy collisions can be explored.
