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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
While auroras are a beautiful sight on Earth, the solar activity that causes them can wreak havoc with space-based infrastructure like satellites. Using artificial intelligence to predict these disruptive solar events was a focus of KX’s work with FDL.Credit: Sebastian Saarloos In the summer of 2024, people across North America were amazed when auroras lit up the night sky across their hometowns, but the same solar activity that makes auroras can cause disruptions to satellites that are essential to systems on Earth. The solution to predicting these solar events and warning satellite operators may come through artificial intelligence.
The Frontier Development Lab of Mountain View, California, is an ongoing partnership between NASA and commercial AI firms to apply advanced machine learning to problems that matter to the agency and beyond. Since 2016, the Frontier Development Lab has applied AI on behalf of NASA in planetary defense, Heliophysics, Earth science, medicine, and lunar exploration.
Through a collaboration with a company called KX Systems, the Frontier Development Lab looked to use proven software in an innovative new way. The company’s flagship data analytics software, called kdb+, is typically used in the financial industry to keep track of rapid shifts in market trends, but the company was exploring how it could be used in space.
Between 2017 and 2019, KX Systems participated in the Frontier Development Lab partnership through NASA’s Ames Research Center in Silicon Valley, California. Working with NASA scientists, KX applied the capabilities of kdb+ to searching for exoplanets and predicting space weather, areas which could be improved with AI models. One question the Frontier Development Lab worked to answer was whether kdb+ could forecast the kind of space weather that creates the auroras to predict when GPS satellites might experience signal interruption due to the Sun.
By importing several datasets monitoring the ionosphere, solar activity, and Earth’s magnetic field, then applying machine learning algorithms to them, the Frontier Development Lab researchers were able to predict disruptive events up to 24 hours in advance.
While this was a scientific application of AI, KX Systems says some of this development work has made it back into its commercial offerings, as there are similarities between AI models developed to find patterns in satellite signal losses and ones that predict maintenance needs for industrial manufacturing equipment.
A division of FD Technologies plc., KX Systems is a technology company that offers database management and analytics software for customers that need to make decisions quickly. While KX started in 1993, its AI-driven business has grown considerably, and the company credits work done with NASA for accelerating some of its capabilities.
From protecting valuable satellites to keeping manufacturing lines moving at top performance, pairing NASA’s expertise with commercial ingenuity is a combination for success.

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.
