Hubble Spies Galaxy with Lots to See
This NASA/ESA Hubble Space Telescope features the galaxy NGC 7456. ESA/Hubble & NASA, D. Thilker While it may appear as just another spiral galaxy among billions in the universe, this image from the NASA/ESA Hubble Space Telescope reveals a galaxy with plenty to study. The galaxy, NGC 7456, is located over 51 million light-years away in the constellation Grus (the Crane).
This Hubble image reveals fine detail in the galaxy’s patchy spiral arms, followed by clumps of dark, obscuring dust. Blossoms of glowing pink are rich reservoirs of gas where new stars are forming, illuminating the clouds around them and causing the gas to emit this tell-tale red light. The Hubble observing program that collected this data focused on the galaxy’s stellar activity, tracking new stars, clouds of hydrogen, and star clusters to learn how the galaxy evolved through time.
Hubble, with its ability to capture visible, ultraviolet, and some infrared light, is not the only observatory focused on NGC 7456. ESA’s XMM-Newton satellite imaged X-rays from the galaxy on multiple occasions, discovering many so-called ultraluminous X-ray sources. These small, compact objects emit terrifically powerful X-rays, much more than researchers would expect, given their size. Astronomers are still trying to pin down what powers these extreme objects, and NGC 7456 contributes a few more examples.
The region around the galaxy’s supermassive black hole is also spectacularly bright and energetic, making NGC 7456 an active galaxy. Whether looking at its core or its outskirts, at visible light or X-rays, this galaxy has something interesting for astronomers to study!

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.

Hubble Homes in on Galaxy’s Star Formation
This NASA/ESA Hubble Space Telescope image features the asymmetric spiral galaxy Messier 96. ESA/Hubble & NASA, F. Belfiore, D. Calzetti This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the spiral galaxy Messier 96 is the brightest of the galaxies in its group. The gravitational pull of its galactic neighbors may be responsible for Messier 96’s uneven distribution of gas and dust, asymmetric spiral arms, and off-center galactic core.
This asymmetric appearance is on full display in the new Hubble image that incorporates data from observations made in ultraviolet, near infrared, and visible/optical light. Earlier Hubble images of Messier 96 were released in 2015 and 2018. Each successive image added new data, building up a beautiful and scientifically valuable view of the galaxy.
The 2015 image combined two wavelengths of optical light with one near infrared wavelength. The optical light revealed the galaxy’s uneven form of dust and gas spread asymmetrically throughout its weak spiral arms and its off-center core, while the infrared light revealed the heat of stars forming in clouds shaded pink in the image.
The 2018 image added two more optical wavelengths of light along with one wavelength of ultraviolet light that pinpointed areas where high-energy, young stars are forming.
This latest version offers us a new perspective on Messier 96’s star formation. It includes the addition of light that reveals regions of ionized hydrogen (H-alpha) and nitrogen (NII). This data helps astronomers determine the environment within the galaxy and the conditions in which stars are forming. The ionized hydrogen traces ongoing star formation, revealing regions where hot, young stars are ionizing the gas. The ionized nitrogen helps astronomers determine the rate of star formation and the properties of gas between stars, while the combination of the two ionized gasses helps researchers determine if the galaxy is a starburst galaxy or one with an active galactic nucleus.
The bubbles of pink gas in this image surround hot, young, massive stars, illuminating a ring of star formation in the galaxy’s outskirts. These young stars are still embedded within the clouds of gas from which they were born. Astronomers will use the new data in this image to study how stars are form within giant dusty gas clouds, how dust filters starlight, and how stars affect their environments.
