Universe Sandbox

We’ve overhauled the underlying architecture of our surface simulation of oceans and atmospheres. This is part of a larger ongoing effort to provide a stronger foundation for new features and performance enhancements. You can also edit barycenter positions and velocities, and explore the newly reorganized Simulation panel. New Surface Simulation FrameworkWe rebuilt our surface simulation and mater

Collision craters form and combine together more realistically. You can also duplicate objects, watch black holes evaporate, and explore a simulation of a newly discovered exosatellite. Creating CratersCraters from collisions with moons and small rock fragments alike are more realistic, blending naturally and better respecting an object’s elevation range and topography. Larger impacts now leave be

Watch winds spread gases across planetary atmospheres, see the unique shape of any selected object with new stylized outlines, and adjust object compositions by percentage. We’ve also focused on eliminating issues with over 50 fixes and improvements. Atmospheric WindsGases now sweep across planetary atmospheres by the newly simulated geostrophic wind. Check it out and customize the wind speed unde

Artemis II MissionThe recent Artemis II mission swept around the far side of the Moon, taking humanity farther than they’ve ever been from Earth. Experience it yourself in our new simulation, Artemis II: Humanity's Farthest Journey.Earthset created in Universe Sandbox. Check out the original Earthset image captured by the Artemis II astronauts.Orion SpacecraftThe Orion Integrity spacecraft from th

Learn about the recently discovered sednoid 2023 KQ14 and why it challenges the Planet Nine hypothesis. Enjoy a handful of bug fixes and quality-of-life improvements like the ability to quickly fly to planets just by selecting an already selected object. We’ve also updated our game engine and improved support for High Dynamic Range (HDR) displays.A New Sednoid In the Outer Solar SystemThe recently

Watch the third-ever discovered visitor from outside our Solar System, 3I/ATLAS, fly past the Sun and see how it compares it to other known interstellar interlopers. We’ve also improved the view that shows what parts of the surface of a planet are illuminated, updated our scientific notation, and more! In the Light of DayThe Daylight view now shows surface illumination of a planet in real-time as

Watch the boiling surface of a star, then set off a supernova and light up your worlds (before your planets are vaporized anyways). Massive stars now leave behind a neutron star or black hole when they end their life with a bang, and much more!Super(nova) LightingSupernovas now brilliantly light up space as they explode and boil away your planets. Be careful looking at them without your Space Gogg
