Are you in need of some serious Moon joy? Get ready for Moon Joy June.
NASA is hosting a month-long art challenge and we would love for you to participate! For every week of June, NASA will introduce a new prompt to inspire artists and creators of all kinds:
June 1-7: LaunchÂ
June 8-14: MoonÂ
June 15-21: CrewÂ
June 22-30: EarthÂ
To share your Moon joy-inspired art on Tumblr, use the hashtag #ArtemisArtShow.
The sky is (not) the limit! We encourage all forms of art, including but not limited to: paintings, drawings, sculptures, dances, music, animations, nail art, latte foam art, poetry, fashion. Choose your favorite medium and share it with us!
Learn more about the challenge in our FAQ. Happy Moon Joy June to all who celebrate!

Want to wake up like an astronaut? Now you can! Check out the Artemis II astronauts' wake-up songs on Spotify.
These songs were chosen by the astronauts for each day of the mission. To end each sleep period aboard Orion, the Mission Control Center at our Johnson Space Center in Houston sends out a special song to the crew. This continues a tradition that reaches back decades to the Gemini VI mission in 1965.

After being assembled, our Nancy Grace Roman Space Telescope has passed final tests, and is being prepared to move to our Kennedy Space Center in Florida, where teams will work to prepare it for a launch in early September 2026.
With a field of view at least 100 times larger than Hubble's, Roman can potentially measure light from a billion galaxies in its lifetime. It will also be able to block starlight to directly see exoplanets and planet-forming disks, complete a statistical census of planetary systems in our galaxy, and settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.
The observatory is named after Dr. Nancy Grace Roman, NASAâs first chief astronomer who made cosmic vistas readily accessible to all by paving the way for telescopes based in space.

This image, released in celebration of Earth Day, shows the terminator â the line between night and day â on Earth. The Artemis II astronauts captured this view on April 2, 2026, during their journey to the Moon.
NASA science improves life on Earth every day. We provide insights on our home planet that can only be gathered from space, which can then be used for disaster response, farming, and more. In addition, our observations of Earth and the technologies we develop provide the foundation needed to explore and sustain human life on the Moon, Mars, and beyond.

This artistâs impression pinpoints many cosmic voids ââ relatively empty bubbles of space.
The universe is home to trillions of galaxies, each chock full of smaller cosmic objects like stars and planets. Since galaxies gravitate together in a web-like pattern, there are also immense open spaces called cosmic voids in between. In those growing, gloomy places, dark energy dominates.
Galaxies in this animation are structured a bit like a Hoberman sphere (a lattice-like toy ball that expands and collapses), growing farther apart as the universe expands.
Zoomed out maps of the universe show that galaxies often cluster together in bright city-like regions. Each cosmic metropolis is connected to others by interstate highways ââŻvast filaments of dark matter, gas, and dust, along which additional galaxies can be found. This large-scale structure is called the cosmic web.
Way out in the boondocks â far from the galaxies and filaments ââŻare the cosmic voids. Theyâve been growing larger for billions of years, emptying out as gravity pulls matter elsewhere.
This animation visualizes the early universe, when the cosmic was full of a hot plasma soup.
Cosmic voids were born when the universe looked extremely different than it does today. Instead of being speckled with stars and galaxies, the cosmos was filled with a sea of plasma (charged particles) that formed a dense, almost uniform fluid.
There were slightly denser kernels of matter, like a single ounce of cinnamon sprinkled into about 13,000 cups of cookie dough! Since the clumps had more mass, their gravity attracted additional material. Those areas grew and grew, drawing more matter together to form stars, galaxies, and galaxy clusters as the universe expanded over billions of years. Meanwhile, the spaces in between became ever emptier.
A simulation of large-scale structure forming under the influence of gravity.
Cosmic voids arenât completely empty, though. They do have sparse galaxies, though they seem to have delayed development. Since thereâs less matter, thereâs weaker gravity pulling things together so stars and galaxies form more slowly. And those galaxies are isolated so theyâre less likely to interact with others, which fuels growth in denser places like galaxy clusters.
But voids are mostly filled with things we canât see. They contain a thin mist of dark matter along with a relatively larger amount of WIMPS (weakly interacting massive particles) like ghostly neutrinos than we find elsewhere in the universe. Since thereâs not very much stuff in voids to create gravity, a different force reigns supreme: dark energy, the mysterious cosmic pressure that seems to be speeding up the universeâs expansion. Since cosmic voids are influenced primarily by dark energy, they offer clues about its behavior.
Astronomers havenât thoroughly studied cosmic voids yet, but our upcoming Nancy Grace Roman Space Telescope will be wide-eyed enough to reveal those desert patches of space like weâve never seen them before. Studying them will show how the universe is put together and how dark energy is pushing galaxies apart.
If you could fly through the cosmic web at hyperspeed, you might see a view like this simulated one!
So far, scientists have found around 1,000 cosmic voids. Romanâs 3D surveys should find tens of thousands more, both large and small, scattered throughout earlier cosmic eras than previous large sky surveys could see. That means weâll be able to watch how the most vacant places get even emptier over billions of years. And astronomers can trace any changes in dark energyâs might by seeing how it stretches voids, where dark energy dominates, across cosmic time.Â

While we're looking up at the Artemis II astronauts journeying to the Moon, they're looking back home at us.Â
In this image, Earth peeks through the capsule window, reminding us that a view like this relies on the ingenuity and hard work of countless people back home.
In the second image, we see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere.
