Space in a New Light | Update 35
Mar 3rd

Immerse yourself in a universe more awe-inspiring and realistic than ever before with our next-generation graphics update! We’ve also added many interface improvements to make controlling the universe easier and more intuitive. You need to see it to believe it.

A More Realistic Graphics Engine
We’ve completely replaced our 10-year-old graphics technology with a state-of-the-art system to make Universe Sandbox look more realistic with physically-based lighting. This new system has required us to update our minimum requirements. Learn more.


Edit Objects Simultaneously
The properties panel now lets you edit multiple objects at once. Use the new Multi-Select tool to select multiple objects and try increasing the mass of every object in the Solar System simultaneously!


Automatic Interface Management
Focus on manipulating the universe instead of managing panels with our new interface system that automatically positions, resizes, and closes panels so you can always see the simulation. This immersive system also provides better support for ultrawide monitors and small screens (like smartphones).


More Highlights
Focus on realism
Making Universe Sandbox look as realistic as possible with physically-based lighting has made stars realistically bright, and collisions result in blindingly realistic hot spots. It turns out there’s a reason you’re not supposed to look at the Sun.



Light from hot planets
Hot objects now emit light based on their temperature so you can use intense impacts to light up your simulation. Previously, only stars could emit light.


Localized glow
Objects now bloom only in hot areas, like those created from lasers or collisions, instead of being surrounded by a single uniform glow.


Smoothly blending clouds
Gas and dust clouds now smoothly pass over planets instead of creating sharp intersections.




Realistic artifacts
The surfaces of human-scale objects, or artifacts like spacecraft, have shiny, reflective metals and rough, rugged edges that interact with light more realistically.


Math in text fields
All object properties now support basic math. Try typing “*42” into a property to multiply by 42 or “/3” to divide by 3, for example.

Explore planet surfaces
Move across the surface of a planet with the WASD keys after landing on it by zooming in for a closer look or using the Land action button in the planet’s Overview tab.

Light intensity with distance
Objects are now always realistically lit based on their physical distance from a light source. Previously, objects were lit with the same intensity based on the camera’s distance from a light source instead of the object’s distance from a light source.


Light warping
Black holes now realistically warp the visuals from other black holes instead of blocking any black holes behind them from being seen. The images below are from the same simulation, with custom colors in the “Before” image that make the black holes easier to see.


Updated View Panel
We’ve improved the View panel with more intuitive controls and lighting options
- You can now see and change the camera target from the View panel.
- Space Goggles provide a more comfortable view that filters the brightness to show the action while preserving realism. Turning them off switches to an unfiltered realistic view where stars, hot objects, and collisions can be blindingly bright.


Action Buttons
We’ve added all-new Action buttons at the top of every Properties tab. Quickly fly to a planet or explode it. Your call. (These buttons replace the Action tab.)

- Save objects or learn more about real astronomical ones with our new Wikipedia button under Additional Actions.

Color maps
We’ve updated our Data View color maps to make them more perceptually uniform. We’ve also added colorblind-friendly color maps and the ability to invert them.



Inspecting the surface
Use the new Inspect tool to quickly see the temperature, material composition, elevation, and other properties of specific points on a planet’s surface.

Selectable Orbital Parent
It’s now easier to create binary systems orbiting a common center of mass (also called a barycenter). View and adjust an object’s Orbital Elements around a binary by selecting the system’s barycenter as the object’s Orbital Parent.


Choose your Startup Simulation
Choose the simulation that automatically opens when Universe Sandbox starts, from any of our included simulations to your own custom work in progress. Just go to
Home > Settings > General > Experience > Startup Simulation

New hotbar
The hotbar has been overhauled so you can add even more shortcuts to manipulate the universe. To edit your hotbar, go to Settings > General > Edit Hotbar or right-click on it and then select “Edit Hotbar.”

A Potentially Dangerous Asteroid
Watch the projected path of one of the most potentially dangerous asteroids ever detected, YR 2024, as it flies near Earth in 2032, or check out a What If? scenario of what the impact might look like under

And
What If Asteroid YR4 2024 Collides with Earth in 2032?

New Minimum Requirements
Improving our graphics means we need to update our minimum hardware requirements to include
- 4 GB dedicated video memory (up from 2 GB). 8 GB is recommended.
- 4 GB RAM (up from 2 GB). 8 GB is recommended.
- 4 GB of free disk space (up from 2 GB).
- Windows:
- DirectX 12
- Windows 10 21H1+ (support for Windows 7 SP1, 8, 8.1, and older versions of Windows 10 will be dropped)
- Apple:
- Silicon (M1 or newer). Intel Mac will no longer be supported.
- Universe Sandbox may still run on Intel-based Macs, but we cannot guarantee good performance for every Intel-based Mac.
- macOS 11.0+ (support for macOS 10.14 and 10.15 will be dropped)
- Silicon (M1 or newer). Intel Mac will no longer be supported.
While it is never fun to have support dropped, this new graphics system will allow us to improve performance and add new features to Universe Sandbox now and well into the future.
We’ll ensure all users affected by this change can always access the version of Universe Sandbox from before this minimum requirements update. Learn how.
