Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars.
Called Pismis 24, this young star cluster resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. Its proximity makes this region one of the best places to explore the properties of hot young stars and how they evolve.
At the heart of this glittering cluster is the brilliant Pismis 24-1. It is at the center of a clump of stars above the jagged orange peaks, and the tallest spire is pointing directly toward it. Pismis 24-1 appears as a gigantic single star, and it was once thought to be the most massive known star. Scientists have since learned that it is composed of at least two stars, though they cannot be resolved in this image. At 74 and 66 solar masses, respectively, the two known stars are still among the most massive and luminous stars ever seen.

Webb captured this sparkling scene of star birth in Pismis 24, a young star cluster about 5,500 light-years from Earth in the constellation Scorpius. This region is one of the best places to explore the properties of hot young stars and how they evolve. Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) Captured in infrared light by Webb’s NIRCam (Near-Infrared Camera), this image reveals thousands of jewel-like stars of varying sizes and colors. The largest and most brilliant ones with the six-point diffraction spikes are the most massive stars in the cluster. Hundreds to thousands of smaller members of the cluster appear as white, yellow, and red, depending on their stellar type and the amount of dust enshrouding them. Webb also shows us tens of thousands of stars behind the cluster that are part of the Milky Way galaxy.
Super-hot, infant stars –some almost 8 times the temperature of the Sun – blast out scorching radiation and punishing winds that are sculpting a cavity into the wall of the star-forming nebula. That nebula extends far beyond NIRCam’s field of view. Only small portions of it are visible at the bottom and top right of the image. Streamers of hot, ionized gas flow off the ridges of the nebula, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks.
Dramatic spires jut from the glowing wall of gas, resisting the relentless radiation and winds. They are like fingers pointing toward the hot, young stars that have sculpted them. The fierce forces shaping and compressing these spires cause new stars to form within them. The tallest spire spans about 5.4 light-years from its tip to the bottom of the image. More than 200 of our solar systems out to Neptune’s orbit could fit into the width its tip, which is 0.14 lightyears.
In this image, the color cyan indicates hot or ionized hydrogen gas being heated up by the massive young stars. Dust molecules similar to smoke here on Earth are represented in orange. Red signifies cooler, denser molecular hydrogen. The darker the red, the denser the gas. Black denotes the densest gas, which is not emitting light. The wispy white features are dust and gas that are scattering starlight.

Patricia White is a contracting officer at NASA’s Stennis Space Center, where she contributes to NASA’s Artemis program that will send astronauts to the Moon to prepare for future human exploration of Mars. NASA/Danny Nowlin When NASA’s Artemis II mission launches in 2026, it will inspire the world through discovery in a new Golden Age of innovation and exploration.
It will be another inspiring NASA moment Patricia White can add to her growing list.
White supports the Artemis program to send astronauts to the Moon to prepare for future human exploration of Mars as a contracting officer at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
White takes special pride in the test operations contract she helped draft. The contract provides support to the Fred Haise Test Stand, which tests the RS-25 engines that will help power NASA’s SLS (Space Launch System) rocket on Artemis missions.
“I was awestruck the first time I witnessed an engine test,” White said. “I remember how small I felt in comparison to this big and fascinating world, and I wondered what that engine would see that I would never be able to see.”
Four RS-25 engines tested at NASA Stennis will help launch Artemis II with four astronauts to venture around the Moon. As the first crewed Artemis mission, it will represent another milestone for the nation’s human space exploration effort.
From Interstate Signs to NASA Career
White describes NASA Stennis as a hidden gem. Growing up in nearby Slidell, Louisiana, she had driven by the interstate signs pointing toward NASA Stennis her entire life.
When she heard about a job opportunity at the center, she immediately applied. Initially hired as a contractor with only a high school diploma in February 2008, White found her motivation among NASA’s ranks.
“I work with very inspiring people, and it only took one person to say, ‘You should go to college’ to give me the courage to go so late in life,” she said.
Hard But Worth It
White began college classes in her 40s and finished at 50. She balanced a marriage, full-time job, academic studies, and household responsibilities. When she started her educational journey, her children were either toddlers or newborns. They were growing up as she stayed in school for nine years while meeting life’s challenges.
“It was hard, but it was so worth it,” she said. “I love my job and what I do, and even though it is crazy busy, I look forward to working at NASA every single day.”
She joined NASA officially in 2013, going from contractor to civil servant.
Setting an Example
White’s proudest work moment came when she brought home the NASA Early Career Achievement award and medal. It served as a tangible symbol of her success she could share with her family.
“It was a long road from being hired as an intern, and we all made extraordinary sacrifices,” she said. “I wanted to share it with them and set a good example for my children.”
As Artemis II prepares to carry humans back to lunar orbit for the first time in over 50 years, White takes pride knowing her work helps power humanity’s return to deep space exploration. Her work is proof that sometimes the most important journeys begin right in one’s own backyard.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Researchers Kelly Gilkey, Cy Peverill, Daniel Phan, Chase Haddix, and Ariel Tokarz test portable, handheld X-ray systems for use during future long-duration space missions at NASA’s Glenn Research Center in Cleveland on Friday, March 21, 2025. Credit: NASA/Sara Lowthian-Hanna As NASA plans future human exploration missions to the Moon, Mars, and beyond, new and unique challenges emerge — like communication delays and limited return-to-Earth options — so enhanced medical care capabilities are critical. Crews will need non-invasive imaging technology to diagnose medical conditions, like broken bones or dental injuries.
Scientists at NASA’s Glenn Research Center in Cleveland are testing portable, handheld X-ray systems for use during future extended space missions. Having portable X-ray capabilities aboard spacecraft would allow astronauts to immediately assess and treat potential injuries or identify equipment issues without having to disassemble the gear.
“Technological innovations like that of the mini-X-ray will help keep our astronauts healthy as we endeavor farther into space than ever before,” said acting NASA Administrator Sean Duffy. “Future missions to the Moon and Mars will be safer due to the research of our scientists at NASA Glenn.”
NASA reviewed more than 200 commercial systems — analyzing size, weight, image quality, ease-of-use, cost, and safety — and selected three systems for further testing: MinXray, Remedi, and Fujifilm.
“We’re working to provide evidence on why a mini-X-ray system should be included in future space exploration,” said Dr. Chase Haddix, a senior biomedical engineering research contractor working for Universities Space Research Association at NASA Glenn. “These X-rays could be used to detect both clinical and non-clinical diagnostics, meaning they can check an astronaut’s body or identify the location of a tear in an astronaut suit.”

“We’re fortunate to have enthusiastic medical and radiography experts right here in our community,” said Dr. Cy Peverill, project task lead at NASA Glenn. “Their knowledge and experience are invaluable as we work to test medical technologies that could significantly improve management of astronaut health on future missions to the Moon or Mars.”
Cuyahoga Community College contributed anatomical phantoms, which are lifelike models of the human body, in its radiography laboratory on the Western Campus and dental hygiene clinical facility at the Metropolitan Campus. Faculty and students consulted with NASA researchers on essential imaging principles, including patient positioning, image acquisition, and image quality.
University Hospitals is partnering with NASA Glenn on a medical study with real patients to compare the performance of the X-ray systems against hospital-grade equipment, focusing on usability, image clarity, and diagnostic accuracy.
“Astronauts live and work in small quarters, much smaller spaces than in a hospital,” Haddix said. “The system must be easy to use since astronauts may not be experienced in radiography. The data from these tests will guide the selection of the most suitable system for future missions.”

NASA researchers theorize that if these systems are successful in high elevations and extreme temperatures on Earth, perhaps they are durable enough for space missions.
Glenn researchers will continue to collect data from all collaborators, including from an X-ray system sourced by SpaceX that launched in April during the Fram2 mission. The crew captured the first human X-ray images in space during their four-day mission to low Earth orbit. NASA plans to select a device near the end of 2025 and will test the chosen system aboard the International Space Station in 2026 or early 2027.
The Mars Campaign Office at NASA Headquarters in Washington and the agency’s Human Research Program at NASA Johnson fund this work as both organizations focus on pursuing technologies and methods to support safe, productive human space travel.
