Astronomers 3D-print stellar nurseries you can hold in your hand

There’s a beautiful new way to visualize the places where stars come from.

Nia Amara is both an astrophysicist and an artist. Those two passions have united in a project that’s helping scientists visualize stellar nurseries, the massive clouds of dust and gas where stars are born.

Amara and her team 3D-printed polished, baseball-size orbs that look like oversized marbles with swirling patterns inside. «We wanted an interactive object to help us visualize those structures where stars form so we can better understand the physical processes,» said Imara in a University of California, Santa Cruz, statement Thursday.

The models are made from opaque resin deposited inside transparent resin, which makes it look like the cosmic clouds are suspended within each globe. The researchers also made half-spheres that give a view into the cross sections of the nurseries.

The patterns came from running simulations of star-forming clouds that show how different processes affect stellar nurseries. Subtle differences in the simulation results stand out when seen in 3D.

«Just aesthetically they are really amazing to look at, and then you begin to notice the complex structures that are incredibly difficult to see with the usual techniques for visualizing these simulations,» said the Flatiron Institute’s John Forbes, co-author of a paper on the project published in The Astrophysical Journal Letters in August.

We’re used to viewing cosmic wonders like galaxies and nebulae on screens. Now imagine those celestial sights being rendered in a way that lets you hold them up, turn them and see into them. That’s a marvelous possibility suggested by Amara’s clever blend of astronomy and art.

NASA’s Artemis II Breaks Record With Trip Around The Moon

In Honor of the Artemis II Mission, Explore the Moon in Fortnite Now

You might not be able to see the moon the way the Artemis II team is, but there’s an educational Fortnite simulation that will get you onto the celestial body’s surface.

You may not be able to explore the vast majesty of space in the same way that the four-person crew of the Artemis II is, but you can still get an up-close-and-personal view of the moon… in Fortnite, at least.

While you may not be able to slingshot around Earth’s own lunar body, space enthusiasts can see a little bit of what the Artemis II crew is seeing by spending time on the Lunar Horizons Fortnite map right now. The map is a creative collaboration between Fortnite’s creator, Epic Games, and the European Space Agency. Lunar Horizons was released in 2024 after extensive testing and play from ESA trainee astronauts.

If you’re looking to learn more about our own orbiting body, the Lunar Horizons map is an educational simulation of the surface of the moon’s South Pole.

It blends game mechanics with learning, as players get to build up their own sterile lunar habitat bases, interact with ESA astronauts and roll around with robotic rovers as they discover informative plaques that contain information about the moon and international space agencies. There are still dangers to navigate, too — a solar storm may strike when you least expect it.

If you’re interested in exploring the moon, we’ve got all the information you need to join in on the Fortnite fun below. And if you’re looking for a more serious livestream during this momentous human achievement, tune into NASA’s feed here.

How to join the Moon Fortnite island while you follow the Artemis II mission

The Lunar Horizons Fortnite map is a great educational simulation that shares details about ESA’s work and catalogs information about humanity’s lunar research.

These three simple steps will get you up and running (or more accurately, taking slow leaps and bounds) on the surface of the Lunar Horizons Fortnite map:

Download Fortnite

If you haven’t played Fortnite before, but you want to check out this limited-time event, you’ll have to download the game. If you’re on PC, you can download Fortnite for free from the Epic Games Store. Console players can navigate the PlayStation Store, Microsoft Store or Nintendo eShop in order to download Fortnite on their devices.

Navigate the in-game menus until you reach the Search button

Once you’re in the game, scroll down past the different official Fortnite game modes and the Discover tab until you find the Search button.

Input the Lunar Horizons island code

In the search bar, you can input a map’s name or its distinct search code in order to find it in the map directory. You can search for the Lunar Horizons map or input the code 3207-0960-6428 to explore this map in time.

Correction, 3:35 p.m. PT: This story initially was in error about the features available in the Lunar Horizons map. There is no Artemis II-specific mission in Fortnite. Rather, the Lunar Horizons map is an educational simulation of part of the moon’s surface.
