This simulation displays a randomly generated sample of 4,000 stars from any galaxy in the universe. Astronomical observations suggest that, on average, each star in the universe hosts at least one exoplanet. When you click on the simulation, 90% of the stars will turn red, illustrating how many in this sample likely have at least one exoplanet in any given region of the cosmos. Once complete, click anywhere to restart the star field with exoplanets simulation.
