Universe Sandbox v31.3: Explore Constellations, Realistic Stars, and Dynamic Glows

Have you ever wondered what it would be like to create your own solar system, collide planets, or watch a star explode? If so, you might want to check out Universe Sandbox, a realistic physics-based space simulator that allows you to do all that and more. Universe Sandbox lets you explore the beauty of our universe and the fragility of our planet with stunning graphics, accurate physics, and interactive features.

In this article, we will take a look at the file “”, which is a compressed version of the latest update for Universe Sandbox. This update introduces several new features and improvements, such as constellations, realistic stellar edges, dynamic object glows, and more. We will explain what these features are, how they work, and how you can use them to enhance your experience with Universe Sandbox.


One of the most noticeable additions in Update 31 is constellations. Constellations are patterns of stars that have been recognized and named by different cultures throughout history. They often represent mythological figures, animals, or objects that have symbolic or astrological meanings.

In Universe Sandbox, you can now explore constellations from different cultures and see how they change over thousands of years as stars move across the sky. You can also create your own constellations and share them with others.

How to explore constellations from different cultures

To explore constellations from different cultures, you need to open a simulation that has stars enabled. You can use one of the default simulations or create your own. Then, go to Home > Open > Constellations. Here you will find constellation sets for 10 cultures: Babylonian, Chinese, Egyptian, Greek/Roman, Inuit, Lakota, Maori, Navajo, Norse, and Tupi.

Select a constellation set that you want to view and click on it. You will see the constellation lines appear on the screen. You can zoom in or out to see more details or change your perspective. You can also click on any star or constellation name to see more information about it.

How to see how constellations change over time

To see how constellations change over time, you need to enable star motion in your simulation. To do this, go to Home > Settings > Simulation > Star Motion. Here you can adjust the speed and direction of star motion. You can also choose whether to use real data or random data for star motion.

Once you have enabled star motion, you can use the time controls at the bottom of go to Effects > Glow. Here you can adjust the intensity and color of the glow for each object. You can also see how the glow changes as you apply different effects to the objects.

You can use this tool to see how object glows change with different scenarios, such as when a planet or moon is hit by an asteroid, when a star goes supernova, when a planet or moon passes in front of another object, and more.

Other Improvements and Fixes

Besides the features mentioned above, Update 31 and Update 31.1 also include several other improvements and fixes that improve the performance, usability, and realism of Universe Sandbox. Some of these are:

– Improved accuracy and stability of orbits and collisions – Improved rendering and lighting of objects and shadows – Improved user interface and controls for various tools and panels – Improved support for VR devices and controllers – Added new simulations, tutorials, and achievements – Fixed various bugs and errors

To access the full list of changes and updates, you can go to Home > Help > What’s New. Here you can see the changelog for each update and learn more about the features and fixes. You can also provide feedback to the developers by clicking on the Feedback button at the bottom of the screen.
