Credit: Minecraft NASA invites gamers, educators, and students to grab their pickaxe and check out its latest collaboration with Minecraft exploring a new world inspired by the agency’s James Webb Space Telescope. The partnership allows creators to experience NASA’s discoveries with interactive modules on star formation, planets, and galaxy types, modeled using real Webb images.
The James Webb Space Telescope Challenges were developed to inspire the next generation of scientists, engineers, and technicians. Through the game, students can immerse themselves in the science and technology behind Webb, deepening their understanding of NASA’s mission and sparking an interest in the real-world applications of science, technology, engineering, and math (STEM).
“We’re thrilled to bring the wonders and science of NASA’s James Webb Space Telescope into the hands of the Artemis Generation through this exciting Minecraft collaboration,” said NASA Deputy Administrator Pam Melroy. “This collaboration is yet another way anyone can join NASA as we explore the secrets of the universe and solve the world’s most complex problems, making space exploration engaging for learners of all ages.”
NASA’s James Webb Space Telescope launched to space Dec. 25, 2021, and has gone on to make detailed observations of the planets within our own solar system, peer into the atmospheres of planets orbiting other stars outside our solar system, and capture images and spectra of the most distant galaxies ever detected.
“NASA’s collaboration with Minecraft allows players to experience the excitement of one of the most ambitious space missions ever,” said Mike Davis, Webb project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “No matter where Webb looks, it sees something intriguing, setting the stage for amazing discoveries yet to come. As people explore the Minecraft world of Webb, we hope they will be inspired to carry that interest further and maybe someday help NASA build future space telescopes.”
Webb is the world’s premier space science observatory. The space telescope is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
NASA’s Office of STEM Engagement provides unique opportunities for students to learn about STEM. In 2023, NASA partnered with Minecraft on an Artemis Challenge where users could build and launch a rocket, guide their Orion spacecraft, and even establish a lunar base alongside their team. Through collaboration with partners such as Microsoft, NASA can share the excitement of space exploration with even more students who are part of the Artemis Generation.

4 Min Read In Odd Galaxy, NASA’s Webb Finds Potential Missing Link to First Stars

NASA, ESA, CSA, STScI, Alex Cameron (Oxford) Looking deep into the early universe with NASA’s James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars. Found approximately one billion years after the big bang, galaxy GS-NDG-9422 (9422) may be a missing-link phase of galactic evolution between the universe’s first stars and familiar, well-established galaxies.

What appears as a faint dot in this James Webb Space Telescope image may actually be a groundbreaking discovery. Detailed information on galaxy GS-NDG-9422, captured by Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, indicates that the light we see in this image is coming from the galaxy’s hot gas, rather than its stars. Astronomers think that the galaxy’s stars are so extremely hot (more than 140,000 degrees Fahrenheit, or 80,000 degrees Celsius) that they are heating up the nebular gas, allowing it to shine even brighter than the stars themselves. NASA, ESA, CSA, STScI, Alex Cameron (Oxford) “My first thought in looking at the galaxy’s spectrum was, ‘that’s weird,’ which is exactly what the Webb telescope was designed to reveal: totally new phenomena in the early universe that will help us understand how the cosmic story began,” said lead researcher Alex Cameron of the University of Oxford.
Cameron reached out to colleague Harley Katz, a theorist, to discuss the strange data. Working together, their team found that computer models of cosmic gas clouds heated by very hot, massive stars, to an extent that the gas shone brighter than the stars, was nearly a perfect match to Webb’s observations.
“It looks like these stars must be much hotter and more massive than what we see in the local universe, which makes sense because the early universe was a very different environment,” said Katz, of Oxford and the University of Chicago.
In the local universe, typical hot, massive stars have a temperature ranging between 70,000 to 90,000 degrees Fahrenheit (40,000 to 50,000 degrees Celsius). According to the team, galaxy 9422 has stars hotter than 140,000 degrees Fahrenheit (80,000 degrees Celsius).
The research team suspects that the galaxy is in the midst of a brief phase of intense star formation inside a cloud of dense gas that is producing a large number of massive, hot stars. The gas cloud is being hit with so many photons of light from the stars that it is shining extremely brightly.
Image B: Galaxy GS-NDG-9422 Spectrum (NIRSpec)
This comparison of the data collected by the James Webb Space Telescope with a computer model prediction highlights the same sloping feature that first caught the eye of astronomer Alex Cameron, lead researcher of a new study published in Monthly Notices of the Royal Astronomical Society. The bottom graphic compares what astronomers would expect to see in a “typical” galaxy, with its light coming predominantly from stars (white line), with a theoretical model of light coming from hot nebular gas, outshining stars (yellow line). The model comes from Cameron’s collaborator, theoretical astronomer Harley Katz, and together they realized the similarities between the model and Cameron’s Webb observations of galaxy GS-NDG-9422 (top). The unusual downturn of the galaxy’s spectrum, leading to an exaggerated spike in neutral hydrogen, is nearly a perfect match to Katz’s model of a spectrum dominated by super-heated gas.
While this is still only one example, Cameron, Katz, and their fellow researchers think the conclusion that galaxy GS-NDG-9422 is dominated by nebular light, rather than starlight, is their strongest jumping-off point for future investigation. They are looking for more galaxies around the same one-billion-year mark in the universe’s history, hoping to find more examples of a new type of galaxy, a missing link in the history of galactic evolution.
NASA, ESA, CSA, Leah Hustak (STScI) In addition to its novelty, nebular gas outshining stars is intriguing because it is something predicted in the environments of the universe’s first generation of stars, which astronomers classify as Population III stars.
“We know that this galaxy does not have Population III stars, because the Webb data shows too much chemical complexity. However, its stars are different than what we are familiar with – the exotic stars in this galaxy could be a guide for understanding how galaxies transitioned from primordial stars to the types of galaxies we already know,” said Katz.
At this point, galaxy 9422 is one example of this phase of galaxy development, so there are still many questions to be answered. Are these conditions common in galaxies at this time period, or a rare occurrence? What more can they tell us about even earlier phases of galaxy evolution? Cameron, Katz, and their research colleagues are actively identifying more galaxies to add to this population to better understand what was happening in the universe within the first billion years after the big bang.
“It’s a very exciting time, to be able to use the Webb telescope to explore this time in the universe that was once inaccessible,” Cameron said. “We are just at the beginning of new discoveries and understanding.”
The research paper is published in Monthly Notices of the Royal Astronomical Society.

For some people, working for NASA is a lifelong dream. For others, it is an interesting and perhaps unexpected opportunity that comes up at just the right time and place.
Everything from family ties and influential teachers to witnessing human spaceflight history and enjoying sci-fi entertainment has helped bring people of all backgrounds together at NASA’s Johnson Space Center in Houston. Several of them recently shared their inspiration to join the NASA team.

“As a kid, I always had my head up looking at the stars. I loved astronomy and seeing videos of humans walking on the Moon fascinated me! I wanted to be the first female to walk on the Moon. When Star Wars came out, I wanted to build my own R2-D2 that could explore the galaxies. I was curious how things worked (so I could build a robot) and a cousin told me about engineering. That was the name for what I wanted to do! So, I went to the High School for Engineering Professions in Houston. The guidance counselor there told me about an opportunity to apply for a summer internship with NASA as a junior. I got in and I’ve worked with NASA as much as I could since I was 16 years old – internships and full-time positions. I may not get the chance to be an astronaut and walk on the Moon, but I know I will play a role in helping achieve that dream for another female and a person of color!”

I went to take your kid to work day and got to stand in front of a booster engine. I’ve wanted to work in the space industry ever since. I almost didn’t enter the field after getting my aerospace degree, but I was fortunate to take an Intro to Human Spaceflight class during my last quarter of college. Without that class and the professor (who had worked at Johnson) I wouldn’t be here today. I’m so glad my path led me here. Johnson is such a great place to be, and I can look back and tell little Margaret that we did it!”

I realized that it was something that I was very passionate about. Thanks to my research work for the Europa Clipper as an undergraduate student, I got my first internship at NASA and subsequently an offer to join the Pathways Program. Now I am part of a small group of engineers that solve entry, descent, and landing problems for multiple missions on Earth, the Moon, and Mars.”

“Dad would take me to the viewing room of the original Mission Operations Control Room (MOCR) during the Apollo era. He was one of the people supporting MOCR in the Staff Support Room. I have worked at Johnson for 27 years [as a contractor] for Lockheed Martin, Hamilton Sundstrand, and Jacobs Technology.”

“In early 1969, when I was a boy, my uncle visited the Johnson Space Center and brought back astronaut and mission photos of the recently completed Apollo 8 lunar orbiting mission. Those photos, coupled with a Saturn V rocket model I assembled, and the Time Life records and books about the Apollo space program my parents purchased for me, sparked my imagination. I knew I wanted to work for NASA one day. It wasn’t until many years later that that dream became a reality, when I joined NASA’s co-op program for college students during my second attempt to become an aeronautical engineer. After I graduated college, I began working full time as a civil servant engineer at Johnson.”

“I remember watching Star Trek and Star Wars as a kid with my dad. I found some of his college notes in a box one day and thought the small, neat print on graph paper pads was really pretty. He went to the University of Texas at Austin to study astrophysics and engineering, but he never got to finish. Fast forward to 2022 and I find myself in Houston for an unknown amount of time, so I decided to go out and make some friends. I met a woman at a Geeky Game Night, and I learned that she was a food scientist at NASA! After talking some more, she told me to send her my resume. Later that week I received a call to set up an interview. I’m still in awe of how that one chance connection led me to my childhood dream of working at NASA.”

“I grew up in a small agricultural village in India. My first introduction to spaceflight was reading Russian cosmonauts’ translated accounts of the Apollo-Soyuz Test Project as a young girl. I am still not sure whether my father picked that book for me on a whim or with a grand dream for his daughter, but it certainly had me hooked. However, I found my true calling to make human spaceflight safer and more efficient after witnessing the Columbia mishap. India, at the time, did not have a human spaceflight program. Thus started a 20-year-long grand adventure of seeking opportunities, pursuing them, immigrating to the United States, and finding my path to NASA, which culminated in a Pathways internship at Johnson.”
– Poonampreet Kaur Josan, three-time Pathways intern, currently supporting the Human Health and Performance Directorate Habitability and Human Factors Branch
