Feb 11: 22.1.2 is a small patch to fix an issue that caused the new physics system (NativeComputation) to occasionally fail on launch and revert to the older, slower system (ManagedComputation).

In the image above, the orbit stretching to the bottom left is 2018 VG18, the most distant known object in the Solar System. The orbit shown here is a preliminary estimate; more accurate data will be available only after years of observation.

Update 22.1 is a small update that adds a few new sims in addition to dozens of improvements and bug fixes.

Check out these sims featuring incredibly distant Solar System objects, including the recently announced 2018 VG18, nicknamed “Farout”:

And here are some highlights from the long list of improvements and fixes:

• Smarter autosaves
• Improvements & fixes for opening, saving, & sharing sims
• Better randomized properties for randomly created objects
• Fixes for issues with frozen fragments & missing orbit previews
• Restored visuals for explosions & fragments

Happy holidays! Stay tuned after the New Year for a recap of this past year and a look at what we’ve got in store for 2019.

Use the new custom sim descriptions to detail the lore of your sci-fi worlds. Or discuss the reality behind the scientific phenomena in your simulations.

This update also includes changes to the interface with new tools for manipulating Property values plus styling improvements throughout. There’s a new autosave system to prevent accidental loss of work, and as always, there are lots of smaller improvements and bug fixes. See the full list of What's New

Notes:
1) Workshop only supports simulations at this time. In the future, we hope to add support for custom textures and models.
2) As of this update, Universe Sandbox no longer supports DirectX 9 or 32-bit operating systems. Users can run the last compatible version by selecting “*directx9-32bit” via Steam Betas (learn how). For more information on our decision to end support for DirectX 9 & 32-bit systems, please see our announcement from earlier this year.

This small update features a new Parker Solar Probe model and new simulations exploring extremes in our Solar System:

Skim past the Sun with the Parker Solar Probe. The probe was launched in August and now has 24 trips around the Sun planned for its 7-year mission. Each year its orbit will take it closer to the Sun as its instruments capture data that will help us better understand our resident star. Its closest approach will bring it within 8.86 solar radii, or 3.83 million miles, of the Sun’s surface, more than 7 times closer than any previous spacecraft.

Add > Objects > Parker Solar Probe

And ride along with New Horizons as it continues through the far reaches of our Solar System past Ultima Thule. After the probe’s flyby of Pluto and its moons in 2015, NASA selected the Kuiper Belt object Ultima Thule as its next target. When New Horizons makes its closest approach on January 1, 2019, Ultima Thule will become the farthest object ever visited by a spacecraft.

Plus: what if our Sun was replaced with one of the largest known stars in the universe, the red supergiant Betelgeuse?

Home > Open > Solar System with Betelgeuse Instead of the Sun

This update also includes an improvement to the accuracy of positions for moons and other objects in the Solar System Now & Real Time simulation, plus a few other smaller improvements and bug fixes.

We are still making slow but steady progress on our larger feature updates, like Steam Workshop, lasers, and Planet Grids. Thanks for everyone's patience!

The Universe Sandbox team pointing at something that was most certainly very interesting. (Left to right, back to front: Jonathan Hoy, Christian Herold, Dave Nelson, Alexander Grønneløv, Georg Steinröhder, Erika Nesvold, Mat Solomon, Dan Dixon, Jules Litman-Cleper, Jenn Seiler, Jared Meier, David Rappo. Not pictured: Jacob Williams, VR Developer (see Unity's story on Jacob for a lovely picture of him), Ryan Macoubrie, Composer

We recently had the privilege and pleasure of uniting [nearly] the whole Universe Sandbox team in person under one roof on the southern coast of Spain for an entire week.

In the seven years since Dan hired two developers to begin work on the latest version of Universe Sandbox, our team has grown to 14 strong. In the past two years alone, we have added six members to our team. So for some of us, this meetup meant seeing familiar faces, but for many, this was the very first time meeting each other in person.

While there are countless benefits to having a remote team spread across the globe, there are drawbacks as well -- not the least of which is the limited opportunity to experience each other not just as coworkers, but as fellow humans with families, wide-reaching interests and hobbies, and large catalogues of cheesy jokes. This was a chance for us to have conversations that weren't at all related to code architecture, simulation performance, pesky bugs, or features on our roadmap. Though of course, we couldn't help ourselves from having those conversations, too.

And importantly, we set aside time to take a step back from the details and appreciate this massively ambitious and unique project we are all a part of and discuss the future that it holds. Believe us when we say our wishlist for the future of Universe Sandbox is not brief.

We've now returned to our homes in Germany, Denmark, Australia, and across the United States in Seattle, Portland, St. Louis, Chicago, Birmingham, D.C., Philadelphia, New York City, and Boston, reinvigorated and excited to get back to making Universe Sandbox bigger and better.

We continue to be ever grateful for all of the support we receive from our loving community that makes all of this possible.

Scroll on for proof that we all get along and had a great time hiking, touring historical sites, and of course, eating:

 
Universe Sandbox will no longer support Windows users running DirectX 9 or 32-bit operating systems later this year. The exact date and release are not known at this time, but we want to give everyone a heads-up.

November 2018: As of Update 22, Universe Sandbox no longer supports DirectX 9 or 32-bit operating systems. Users can run the last compatible version by selecting “*directx9-32bit” via Steam Betas. Learn how
 
 
Short answer:
These are technologies that have been replaced in mainstream computing over a decade ago. There are very few users left on these systems, and it is getting harder to support them as time goes on. This will help us continue to make improvements to performance and stability into the future.

Long answer:
The game engine we use, Unity3D, stopped supporting the DirectX 9 API last year. Unity states that "due to diminishing hardware numbers and the loss of platform support from Microsoft ... continued support of the DirectX 9 API is no longer feasible and is working against the development of new features in Unity." This move mirrors the direction taken by many other companies for their software and video games, including Blizzard's popular Heroes of the Storm.

The same is true for discontinuing support of 32-bit OSes, as hardware manufacturers like Nvidia are no longer updating 32-bit drivers with new features, Apple is gearing up to drop all support for 32-bit applications, and World of Warcraft is now going to be 64-bit only.

The vast majority of Universe Sandbox users are already running 64-bit, and our ability to focus on and develop only this version will help us continue to make improvements to Universe Sandbox's performance and stability into the future.

 
 
This will not affect macOS or Linux users, and if you are on Windows, chances are good that you are already running modern hardware with support for later versions of DirectX and a 64-bit OS that will not be affected by this.

But in case you aren't, here's what you need to know:

• This will end support for any Windows versions below Windows 7 SP1+
• DirectX 10 may work, but we recommend DirectX 11 | Find out which version you're running
• You must run a 64-bit version of Windows | Find out which version you're running

 
 
Upgrade to a newer version of DirectX:
We recommend upgrading to at least DirectX 11. Follow these instructions to find out which version you're running and view information about upgrading, if needed.

Some older GPUs do not support DirectX 11. You will need to find information about your GPU or contact the manufacturer to see what versions of DirectX it supports.

Upgrade to a 64-bit OS:
If you're running Windows 7 through 10, you're able to upgrade to 64-bit for free. Here is one guide for upgrading Windows 10.

You will need to upgrade to a newer version of Windows if you are running a version older than Windows 7.
 
If you can't upgrade:
We will offer a DirectX 9, 32-bit compatible version of Universe Sandbox via Steam. This version will not continue to be updated or supported; it will be the last update before we move onto DirectX 11, 64-bit versions only.

November 2018: As of Update 22, Universe Sandbox no longer supports DirectX 9 or 32-bit operating systems. Users can run the last compatible version by selecting “*directx9-32bit” via Steam Betas. Learn how

This update also includes the 12 recently discovered moons of Jupiter. Initially discovered in March 2017, they have now all been observed several times and their orbits are confirmed. Jupiter now has a total of 79 known moons.

See Jupiter's new moons:
Home > Open > Core > Jupiter's New Moons

They are all very small, around 1 to 2 miles wide. One of the moons is unique, as it orbits in the opposite direction of all of the other moons it is near. “It’s basically driving down the highway in the wrong direction,” said Scott Sheppard, one of the astronomers who made the discovery.

Also: We’re still testing sharing simulations on Steam Workshop. Learn how you can try it out and help us test

July 19: Support for other languages has been officially released in Update 21! Thanks for everyone’s help with testing this feature and contributing to translations. Learn more about 20 Earth Languages & 12 Jovian Moons | Update 21

We are still testing our next big feature:

• Steam Workshop (Sharing Simulations)

Please help us test! Jump into the Community Test build and start sharing and exploring Workshop simulations.



Share simulations to Steam Workshop:
Home > Save > Share to Steam Workshop

Browse & open Steam Workshop simulations:
Home > Workshop

Sharing simulations now will help us test this feature and also help us build up a big catalog of sims on Steam Workshop, so we can show off the creativity of the Universe Sandbox community from day one of the official Workshop release.

As part of our redesigned save dialog and support for Steam Workshop, simulations now support custom descriptions that appear when the simulation loads. And even cooler? These descriptions support the same BBCode formatting that Steam does. Two differences: It also supports images with [img] URL [/img], and even animated GIFs! But it does not support the noparse tags.

• Right-click on the game title in your Steam Library
• Click on ‘Properties’
• Select the ‘Betas’ tab
• Set the dropdown menu to 'community-test'
• Close the Properties window
• Steam will now update Universe Sandbox ² to the Community Test build
• Once updated, launch Universe Sandbox ²

Please note: We’ve done extensive testing on this feature, but this is a Community Test build for a reason. There are still changes we have planned, and you may encounter bugs. If you do, please let us know on our forum or in-game via Home > Send Feedback.

Thanks for testing and for your patience!

See What's New | Community Tests for a list of changes

This update features improvements to orbits & motion:

• Improved Support for Hyperbolic Trajectories
• More Precise Control of Orbital Elements
• Reorganized Motion Tab in Properties Panel

A hyperbolic trajectory is the path of an object that is affected by the gravity of a parent object, but not enough to be pulled into an orbit. Instead, it escapes the gravitational influence and continues toward infinity.  

Learn more about hyperbolic trajectories:

• Home > Open > An Interstellar Object with a Hyperbolic Trajectory

There is also a new sim of Jupiter’s co-orbital retrograde asteroid 2015 BZ509:

• Home > Open > Historical > Retrograde Asteroid 2015 BZ509

Update 20.7 also has many smaller improvements, including autosaves and a revamped What’s New panel, along with a bunch of bug fixes.

-----------------------

A few weeks ago we talked about our upcoming support for Steam Workshop, a feature we've been working on in parallel to our work on Update 21's big features, Planet Grids & Lasers.

Now we're excited to announce another upcoming feature for Universe Sandbox ²: support for multiple languages. As with Steam Workshop, we still have work to do on this, but we've made great progress. Just check out the video above for proof. You may spot some words that haven't been translated yet, and some things may look a bit off, but all the big pieces are in place and everything is working smoothly.

If you're familiar with any of the languages used in the video, you may also note that some translations are a bit strange. Currently, everything has been translated with Google Translate, which has been a very useful tool, but it does not always produce the most accurate results. In the future, we’ll have professional translations for the most widely used languages.

Universe Sandbox ² is constantly growing and evolving; it's important that we have help from others to build and maintain translations into any number of languages. This is where you, the community, come in.

Along with the ability to switch languages at any time, you will also be able to help translate Universe Sandbox ² with a very easy-to-use integration with Crowdin. Crowdin is a system that helps manage localization projects by making it easy for anyone to submit new translations and vote on the best ones.

Once we have everything ready, we'll be sure to make an announcement and include full instructions for anyone who wants to help.

Please note: Localization is not yet available in Universe Sandbox ². It is still a work-in-progress feature and will look different in the future.

Big thanks to our developer, Dave, for all of his work on supporting other languages. We’re excited to make Universe Sandbox ² more accessible to people all over the world.
