August 26: Updates 23.1.2 and 23.1.1 are hotfixes for startup issues for VR users and users with older processors.

Run Steam to download Update 23.1, or buy Universe Sandbox via our website or the Steam Store.

This update adds a bunch of improvements and fixes to the galaxy simulation, making for more stable and accurate galaxies and better collisions. There’s also a new and improved Introduction tutorial and a new simulation of 2019 OK, the near-Earth asteroid that surprised astronomers when it was observed just a day before it flew past us on July 25, 2019.

Some more highlights from Update 23.1:

  • Improved handling for galaxies & smaller-scale objects
  • More accurate galaxy masses
  • New galaxy Star Count property
  • New Teleport tool
  • Many smaller improvements & bug fixes

The new Introduction is designed for anyone who is just getting started with Universe Sandbox, but we encourage even the most seasoned creators and destroyers to check it out:
