Arcand A bouquet of thousands of stars in bloom has arrived. This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus.
By combining X-ray data from NASA’s Chandra X-ray Observatory (blue and green) with optical data from NASA’s Hubble Space Telescope (yellow) and radio data from the Atacama Large Millimeter/submillimeter Array (orange), this stellar arrangement comes alive.

Arcand Otherwise known as the Tarantula Nebula, 30 Dor is located about 160,000 light-years away in a small neighboring galaxy to the Milky Way known as the Large Magellanic Cloud (LMC). Because it one of the brightest and populated star-forming regions to Earth, 30 Dor is a frequent target for scientists trying to learn more about how stars are born.
With enough fuel to have powered the manufacturing of stars for at least 25 million years, 30 Dor is the most powerful stellar nursery in the local group of galaxies that includes the Milky Way, the LMC, and the Andromeda galaxy.
The massive young stars in 30 Dor send cosmically strong winds out into space. Along with the matter and energy ejected by stars that have previously exploded, these winds have carved out an eye-catching display of arcs, pillars, and bubbles.
A dense cluster in the center of 30 Dor contains the most massive stars astronomers have ever found, each only about one to two million years old. (Our Sun is over a thousand times older with an age of about 5 billion years.)
This new image includes the data from a large Chandra program that involved about 23 days of observing time, greatly exceeding the 1.3 days of observing that Chandra previously conducted on 30 Dor. The 3,615 X-ray sources detected by Chandra include a mixture of massive stars, double-star systems, bright stars that are still in the process of forming, and much smaller clusters of young stars.
There is a large quantity of diffuse, hot gas seen in X-rays, arising from different sources including the winds of massive stars and from the gas expelled by supernova explosions. This data set will be the best available for the foreseeable future for studying diffuse X-ray emission in star-forming regions.
The long observing time devoted to this cluster allows astronomers the ability to search for changes in the 30 Dor’s massive stars. Several of these stars are members of double star systems and their movements can be traced by the changes in X-ray brightness.
A paper describing these results appears in the July 2024 issue of The Astrophysical Journal Supplement Series. NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description
This release features a highly detailed composite image of a star-forming region of space known as 30 Doradus, shaped like a bouquet, or a maple leaf.
30 Doradus is a powerful stellar nursery. In 23 days of observation, the Chandra X-ray telescope revealed thousands of distinct star systems. Chandra data also revealed a diffuse X-ray glow from winds blowing off giant stars, and X-ray gas expelled by exploding stars, or supernovas.
In this image, the X-ray wind and gas takes the shape of a massive purple and pink bouquet with an extended central flower, or perhaps a leaf from a maple tree. The hazy, mottled shape occupies much of the image, positioned just to our left of center, tilted slightly to our left. Inside the purple and pink gas and wind cloud are red and orange veins, and pockets of bright white light. The pockets of white light represent clusters of young stars. One cluster at the heart of 30 Doradus houses the most massive stars astronomers have ever found.
The hazy purple and pink bouquet is surrounded by glowing dots of green, white, orange, and red. A second mottled purple cloud shape, which resembles a ring of smoke, sits in our lower righthand corner.

Ambiguity.
That’s the word that comes to mind when documentary photographers start each day at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
PACE mission photographer Denny Henry and lead documentary photographer Desiree Stover pose for selfies in the clean room.Credits: NASA “You walk in and think one thing is happening,” said OCI’s lead documentary photographer Desiree Stover. “But in an instant things change – maybe goes wrong –- and you need to be ready to capture it.”
From build to testing to launch, one figure is always present in the background capturing the story of each Goddard mission – the documentary photographer.
In honor of #WorldPhotoDay, follow along as two of our documentarians share what it’s like to capture the story of Goddard’s latest mission build PACE.
PACE or Plankton, Aerosol, Cloud, ocean Ecosystem, is set to launch in early 2024. Its goal is to see ocean and atmosphere features in unparalleled detail. By measuring the intensity of the color that reflects from Earth’s ocean surface, PACE will capture fine details about tiny plant-like organisms and algae that live in the ocean, called phytoplankton, that are the basis of the marine food web and generate half of Earth’s oxygen.
Crafting the Story
For Stover and her partner Denny Henry, PACE’s lead mission photographer, the story starts with the smallest details.
“I think one of the first things I photographed was the outside of a circuit port box. It was literally an empty metal box,” said Henry, who started photographing PACE in 2020, right before the pandemic. “It might be small, but it’s part of a system that’s going to do big things.”

By the end of the day, the original plan has likely been changed, multiple times.
“Some days we might shoot eight photos, other days it might be hundreds or more,” Stover said.
PACE, or Plankton, Aerosol, Cloud, ocean Ecosystem, is set to launch in early 2024. Its goal is to see ocean and atmosphere features in unparalleled detail.Credits: NASA Images captured during shoots are used for a variety of things, especially technical components of the mission. This includes documenting builds, spotting mistakes and testing.
Stover got her start at Goddard by photographing NASA’s James Webb Space Telescope before switching to capturing imagery of Goddard’s small instruments, including PACE’s Ocean Color Instrument, or OCI. This advanced sensor will enable continuous measurement of light throughout the ultraviolet to shortwave infrared spectrum to better understand Earth’s ocean and atmosphere.
She says she’s still in awe that her teammates trust her “eye.”
“One of the most fascinating things about working here is that we have a specific job,” she said. “And even though engineers can pick up a camera and take photos, they don’t. They know we’re the experts at it. They trust our eyes to tell and capture the story.”
Henry said one of the most memorable days he’s documented so far was watching the PACE team integrate the SPEXone instrument into the spacecraft.
“All the partners were there as I photographed. It was a big deal,” he said. “I captured every bolt all the way to the mounting. It’s important to get these details. Six months from now someone who wasn’t there might want to see what was done in what order.”
Henry said that capturing images is only part of the job. For every hour of shooting, there’s also an hour spent processing and working with partners to ensure things were documented correctly.
Playing Detective
While telling the story is important, Stover says that part of the job is speaking up, especially when you notice something wrong.
During one assignment documenting vibration testing, Stover noticed that OCI’s Earth shade looked different.
“We took the bagging off and could see tape peeling off the radiator panels, possibly loose wires in certain places,” she said. “When I saw this, I thought back to what it was like when we shot this the first time.”

When Stover saw the tape, she got to work ensuring her hunch was right.
She sent a series of images to the thermal team lead letting him know what she found. Plans were already underway to change the design.
The unexpected
Stover and Henry agree that documenting missions has come with some interesting experiences.
Both had to undergo fall protection harness training in the event they had to climb around one of Goddard’s cleanrooms, something that happened to Stover during one assignment.
“Once I was up in Building 29’s high bay. Like up at the very top in the crane rafters shooting. I never thought I was afraid of heights until that moment,” she said. “But I focused on the image and what task I was accomplishing and completed the assignment without issue.”
Henry said adjusting to Covid-19 required a lot of flexibility, especially with sudden changes.
“This is not a job you can do from home,” he said. “After a few months, we adapted.”

With the pandemic restrictions, PACE heavily relied on his images to note how things changed and why issues occurred.
As PACE heads toward big milestones in the next year, both Stover and Henry are excited to see their work come together, including the day of launch.
They both agreed that photographing the teams involved in each aspect of PACE’s build is especially rewarding as they help create mementos that go along with their mission’s story.

2 Min Read More Than 400 Lives Saved with NASA’s Search and Rescue Tech in 2024
NASA Artemis II crew members are assisted by U.S. Navy personnel as they exit a mockup of the Orion spacecraft in the Pacific Ocean during Underway Recovery Test 11 (URT-11) on Feb. 25, 2024. Credits: NASA/Kenny Allen NASA’s Search and Rescue technologies enabled hundreds of lives saved in 2024.NASA/Dave Ryan Did you know that the same search and rescue technologies developed by NASA for astronaut missions to space help locate and rescue people across the United States and around the world?
NASA’s collaboration with the international satellite-aided search and rescue effort known as Cospas-Sarsat has enabled the development of multiple emergency location beacons for explorers on land, sea, and air.
Of the 407 lives saved in 2024 through search and rescue efforts in the United States, NOAA (National Oceanic and Atmospheric Administration) reports that 52 rescues were the result of activated personal locator beacons, 314 from emergency position-indicating radio beacons, and 41 from emergency locator transmitters. Since 1982, more than 50,000 lives have been saved across the world.
Using GPS satellites, these beacons transmit their location to the Cospas-Sarsat network once activated. The beacons then provide the activation coordinates to the network, allowing first responders to rescue lost or distressed explorers.
NASA Artemis II crew members are assisted by U.S. Navy personnel as they exit a mockup of the Orion spacecraft in the Pacific Ocean during Underway Recovery Test 11 (URT-11) on Feb. 25, 2024, while his crewmates look on. URT-11 is the eleventh in a series of Artemis recovery tests, and the first time NASA and its partners put their Artemis II recovery procedures to the test with the astronauts.NASA/Kenny Allen The Search and Rescue Office, part of NASA’s SCaN (Space Communications and Navigation) Program, has assisted in search and rescue services since its formation in 1979 Now, the office is building on their long legacy of Earth-based beacon development to support crewed missions to space.
The beacons also are used for emergency location, if needed, as part of NASA’s crew launches to and from the International Space Station, and will support NASA’s Artemis campaign crew recovery preparations during future missions returning from deep space. Systems being tested, like the ANGEL (Advanced Next-Generation Emergency Locator) beacon, are benefitting life on Earth and missions to the Moon and Mars. Most recently, NASA partnered with the Department of Defense to practice Artemis II recovery procedures – including ANGEL beacon activation – during URT-11 (Underway Recovery Test 11).
Miniaturized Advanced Next-Generation Emergency Locator (ANGEL) beacons will be attached to the astronauts’ life preserver units. When astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hanse splash back down to Earth — or in the unlikely event of a launch abort scenario — these beacons will allow them to be found if they need to egress from the Orion capsule.NASA The SCaN program at NASA Headquarters in Washington provides strategic oversight to the Search and Rescue office. NOAA manages the U.S. network region for Cospas-Sarsat, which relies on flight and ground technologies originally developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. U.S. region rescue efforts are led by the U.S. Coast Guard, U.S. Air Force, and many other local rescue authorities.
