April 18: 22.2.1 & 22.2.2 address a Mac-specific issue that caused crashes while using the Add panel. Known Mac issue: loading “Solar System Planets, Moons, and Large Objects” simulation sometimes results in a crash.

Run Steam to download Update 22.2, or buy Universe Sandbox via our website or the Steam Store.

This update adds improved vaporization effects that are more accurate and colorful. It also introduces an experimental version of our new physics system that makes gravity simulation faster, more stable, and more accurate. We’d love it if you tried it out and helped us test it!

Please remember this system is still experimental. If you experience any problems, let us know! You can report any issues on our forums (local forum | Steam forum) or via Home > Send Feedback.

There are also dozens of smaller improvements and fixes. Here are some of the highlights:

  • Added Fahrenheit as a temperature unit
  • Added Filipino to available languages
  • Improved Search in Open panel
  • Trails & orbits work on older hardware again
  • Object lighting on Linux works again
  • New simulation with all planets, moons, and large Solar System objects

Check out a full list of What’s New in Update 22.2


We’re excited for the upcoming official release of this new physics system so that everyone can enjoy the improvements to performance and accuracy. We’re also working on brand new galaxies and, while we had a setback with Surface Grids & Lasers, we are now making good progress again. Learn more about our progress on these features
