June 28: Update 23.0.1 is a small patch to fix an issue with tidal heating.

This update adds brand new galaxies that are much more interactive, accurate, and varied, making it easier than ever to create and customize on a galactic scale.

Three Types of Galaxies

Use the Add tool to procedurally generate a Spiral, Elliptical, or Irregular galaxy and add it to any simulation. Or select from galaxies like the Milky Way, Andromeda, or IC 1101, one of the largest known galaxies.

Accurate, Data-Driven Motion & Visuals

The motion and shape of the galaxy are now determined by its type and properties. You'll also see red-yellow elliptical galaxies where the stars are older and bluer spiral arms where the stars are younger and hotter.

Full Customization

Adjust standard properties like mass and radius plus unique galaxy properties like the number of spiral arms and amounts of dust and gas.
