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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA is kicking off the 2026 Student Launch challenge, looking for new student teams to design, build, and launch high-powered rockets with a scientific or engineering payload next April.
The agency is seeking proposals until Monday, Sept. 22. Details about this year’s challenge are in the 2026 handbook, which outlines the requirements for middle school, high school, and college students to participate. After a competitive proposal selection process, selected teams must meet documentation milestones and undergo detailed reviews throughout the activity year.
NASA’s Student Launch, a STEM competition, officially kicks off its 26th anniversary with the 2026 handbook. “These bright students rise to a nine-month challenge for Student Launch that tests their skills in engineering, design, and teamwork,” said Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region. “They are part of the Golden Age of explorers – the future scientists, engineers, and innovators who will lead us into the future of space exploration.”
Student Launch will culminate with on-site events starting on April 22, 2026. Final launches are scheduled for April 25, at Bragg Farms in Toney, Alabama, near NASA’s Marshall Space Flight Center in Huntsville, Alabama.
Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2026 season, the payload challenge will take inspiration from the Artemis missions, which seek to explore the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars. This year’s payload challenge tasks college and university teams with designing, building, and flying a habitat to safely house four STEMnauts – non-living objects representing astronauts – during extended missions. The habitat must include equipment capable of both collecting and testing soil samples to support agricultural research operations.
Nearly 1,000 students participated in the 2025 Student Launch competition – making up 71 teams from across the United States. Teams launched their rockets to an altitude between 4,000 and 6,000 feet, while attempting to make a successful landing and executing the payload mission.
NASA Student Launch has been at the forefront of experiential education, providing students from middle school through university with unparalleled opportunities to engage in real-world engineering and scientific research.
John Eckhart
Technical Coordinator, Student Launch
Former NASA Marshall Director Art Stephenson started Student Launch in 2000 as a student rocket competition at the center. Just two university teams competed in the inaugural challenge – Alabama A&M University and the University of Alabama in Huntsville. The challenge continues to soar with thousands of students participating in the STEM competition each year, and many going on to a career with NASA.
NASA Marshall’s Office of STEM Engagement hosts Student Launch to provide students with real-world experiences that encourage them to pursue degrees and careers in science, technology, engineering, and mathematics. Student Launch is one of several NASA Artemis Student Challenges – a variety of activities that expose students to the knowledge and technology required to achieve the goals of the agency’s Artemis campaign.
In addition to NASA Office of STEM Engagement’s Next Generation STEM project, NASA Space Operations Mission Directorate, Northrop Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and, Bastion Technologies provide funding and leadership for the Student Launch competition.

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.
