Hubble Surveys Cloudy Cluster
This new NASA/ESA Hubble Space Telescope image features the nebula LMC N44C. ESA/Hubble & NASA, C. Murray, J. Maíz Apellániz This new NASA/ESA Hubble Space Telescope image features a cloudy starscape from an impressive star cluster. This scene is in the Large Magellanic Cloud, a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa. With a mass equal to 10–20% of the mass of the Milky Way, the Large Magellanic Cloud is the largest of the dozens of small galaxies that orbit our galaxy.
The Large Magellanic Cloud is home to several massive stellar nurseries where gas clouds, like those strewn across this image, coalesce into new stars. Today’s image depicts a portion of the galaxy’s second-largest star-forming region, which is called N11. (The most massive and prolific star-forming region in the Large Magellanic Cloud, the Tarantula Nebula, is a frequent target for Hubble.) We see bright, young stars lighting up the gas clouds and sculpting clumps of dust with powerful ultraviolet radiation.
This image marries observations made roughly 20 years apart, a testament to Hubble’s longevity. The first set of observations, which were carried out in 2002–2003, capitalized on the exquisite sensitivity and resolution of the then-newly-installed Advanced Camera for Surveys. Astronomers turned Hubble toward the N11 star cluster to do something that had never been done before at the time: catalog all the stars in a young cluster with masses between 10% of the Sun’s mass and 100 times the Sun’s mass.
The second set of observations came from Hubble’s newest camera, the Wide Field Camera 3. These images focused on the dusty clouds that permeate the cluster, providing us with a new perspective on cosmic dust.

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!

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.

Hubble Observes Noteworthy Nearby Spiral Galaxy
This NASA/ESA Hubble Space Telescope image features the nearby spiral galaxy NGC 2835. ESA/Hubble & NASA, R. Chandar, J. Lee and the PHANGS-HST team This NASA/ESA Hubble Space Telescope image offers a new view of the nearby spiral galaxy NGC 2835, which lies 35 million light-years away in the constellation Hydra (the Water Snake). The galaxy’s spiral arms are dotted with young blue stars sweeping around an oval-shaped center where older stars reside.
This image differs from previously released images from Hubble and the NASA/ESA/CSA James Webb Space Telescope because it incorporates new data from Hubble that captures a specific wavelength of red light called H-alpha. The regions that are bright in H-alpha emission are visible along NGC 2835’s spiral arms, where dozens of bright pink nebulae appear like flowers in bloom. Astronomers are interested in H-alpha light because it signals the presence of several different types of nebulae that arise during different stages of a star’s life. Newborn, massive stars create nebulae called H II regions that are particularly brilliant sources of H-alpha light, while dying stars can leave behind supernova remnants or planetary nebulae that can also be identified by their H-alpha emission.
By using Hubble’s sensitive instruments to survey 19 nearby galaxies, researchers aim to identify more than 50,000 nebulae. These observations will help to explain how stars affect their birth neighborhoods through intense starlight and winds.

Sun at the Center: Teacher Ambassadors Bring Heliophysics to Classrooms Nationwide
For the fourth year in a row, the American Association of Physics Teachers, a collaborator on the NASA Heliophysics Education Activation Team (HEAT), selected eight new educators to serve as ambassadors for heliophysics education. Meeting in Boulder, CO, from July 14-17, 2025, these teachers met to work through AAPT’s lessons that bring physics content to life in the context of NASA heliophysics missions and the Framework for Heliophysics Education.
The Ambassador program began in 2022 as an effort to identify highly-motivated secondary and tertiary educators who could encourage other educators to integrate NASA content into their teaching. The impact is clear – a handful of Ambassadors in the past few years have joined the program directly as a result of previous educators.
New Jersey high school physics and astronomy teacher Erin Bontempo first learned about the program at the spring meeting of the National Science Teaching Association (NSTA). She attended a workshop led by Hava Turkakin and Francesca Viale, 2023 and 2024 Ambassadors and community college faculty. In a 60-minute interactive session, Hava and Francesca shared brief snapshots of four of AAPT’s lessons, connecting heliophysics to topics traditionally taught in core science courses, such as motion, light, and magnetism.
Erin was intrigued by the lessons she saw: “When I began teaching astronomy eight years ago, I knew little about space. Ever since, I have been an avid student, constantly reading, researching, and in awe of the current NASA missions. I often look for courses to take to further my knowledge, and I feel like this is a perfect fit. When I attended the NSTA conference session on HEAT, it just clicked. The lessons that they brought using real data are the kind of exposure students need.”
Ultimately, Erin was invited to be an Ambassador herself, along with seven other educators, to take part in the summit experience in Boulder. In addition to learning about heliophysics with the AAPT leadership team, the group visited the National Space Weather Prediction Center to hear first-hand how NASA, NOAA, and various federal and international agencies work to understand and respond to our changing Sun.
Since the program began, 32 Ambassadors have been identified and participated in the multi-day professional learning experience, followed by a year of leadership and outreach to other educators. Beyond their own classrooms, they have reached educators across 36 local, state, and national events, holding extended workshops with nearly 500 other teachers.
In addition to AAPT’s lessons, the AAPT/NASA HEAT Resources webpage also provides the names and states for all ambassadors as well as the schedule and topics for the upcoming ‘Physics in an Astronomy Context’ series of free online mini-workshops being planned for the 2025 Fall semester.
