Launch Your Creativity with Space Crafts

Stardust Slime

Did you know that most of your household ingredients are made of stardust? And so are you! Nearly every naturally occurring element was forged by living or dying stars.

Take the baking soda in this slime recipe, for example. It’s made up of sodium, hydrogen, carbon, and oxygen. The hydrogen was made during the big bang, right at the start of the universe. But the other three elements were created by dying stars. So when you show your friends your space-y slime, you can tell them it’s literally made of stardust!

Space Suckers

Now let’s travel a little farther, past Earth’s atmosphere and into the realm of space. That’s where Roman is headed once the whole observatory is complete and passes all of its testing!

Roman will scan the skies from space to make it extra sensitive to faint infrared light. It’s harder to see from the ground because our atmosphere scatters and absorbs infrared radiation, which obscures observations.

Some astronauts have reported that space smells metallic or like gunpowder, but don’t worry — you can choose a more pleasant flavor for your space suckers!

Fizzy Planets

As we move toward our outer solar system, we’ll pass the orbits of the gas giant planets Jupiter and Saturn. While they don’t actually fizz like the mini planets you can make at home, they do have some pretty exotic chemistry that stems from their extreme pressures, temperatures, and compositions. For example, the hydrogen in their cores behaves like liquid metal instead of a gas. It even conducts electricity!

Roman will use multiple planet-spotting techniques –– microlensing, transits, and direct imaging –– to help us study a variety of worlds, including both gas giants and rocky worlds similar to our own.

Marshmallow Constellations

As we venture farther out into space, we’ll reach some familiar stars! Constellations are groups of stars that appear close together in the sky as seen from Earth. But if you actually journeyed out to them, you might be surprised to discover that they’re often super far apart from each other!

Though constellations aren’t made of stars that are actually bound together in any way, they can still be useful for referencing a cosmic object’s location in the sky. For example, you can use a pair of binoculars or a telescope to take a look at the nebula found beneath Orion’s Belt, marked by the glitter patch in the recipe card above!

You can find the constellation printables here.

Black Hole Bath Bombs

Black holes –– objects with such strong gravity that not even light can escape their clutches –– lurk unseen throughout our galaxy. Stray too close to one and you’re in for a wild ride! But they aren’t cosmic vacuum cleaners, despite what you may have grown to believe. Just keep your distance and they’ll affect you the same way as any other object of the same mass.

Astronomers have found dozens of black holes in our galaxy by seeing how their gravity affects nearby objects. But there may be 100 million more that lack a visible companion to signal their presence. Roman will find some of these solitary black holes by seeing how their gravity focuses the light from farther stars.

Galaxy in a Jar

Now let’s go so far we can see our Milky Way galaxy from the outside — something many astronomers probably wish they could do at times!

Sort of like how Earth’s atmosphere can affect our view of space, dust in our galaxy can get in the way, too. That makes it easier to study other galaxies than our own in some ways! Roman’s combination of a large field of view, crisp resolution, and the ability to peer through dust make it the ideal instrument to study the Milky Way. The mission will build on previous observations to generate the most detailed map of our galaxy to date.

Pinwheel Galaxy Pinwheels

As we continue our cosmic excursion, you’ll see other galaxies sprinkled throughout space. Many are spiral galaxies, like our Milky Way and the Pinwheel Galaxy from the craft described above. (You can find more detailed instructions and the printout you’ll need here.)

But galaxies come in other varieties, too. Through Roman’s wide, deep surveys, astronomers are sure to see every type. Scientists will study the shapes and distances of billions of galaxies to help us understand dark energy — a mysterious pressure that’s speeding up the universe’s expansion.

Universe Dough

We’re nearing the end of our voyage, having traveled so far through space and time that we can take in the whole universe! We’ve learned a lot about it, but there are still plenty of open questions. Some of its biggest components, dark energy and dark matter (invisible matter seen only via its gravitational influence), are huge mysteries Roman will explore. And since the observatory will reveal such large, deep swaths of space, who knows what new puzzles we’ll soon uncover!
