Zamani (ESA/Hubble) As part of ESA/Hubble’s 35th anniversary celebrations, ESA is sharing a new image series revisiting stunning, previously released Hubble targets with the addition of the latest Hubble data and new processing techniques.
This new image showcases the dazzling young star cluster NGC 346. Although both the James Webb Space Telescope and Hubble have released images of NGC 346 previously, this image includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.
This dazzling NASA/ESA Hubble Space Telescope image features the young star cluster NGC 346. ESA/Hubble & NASA, A. Nota, P. Massey, E. Sabbi, C. Murray, M. Zamani (ESA/Hubble) NGC 346 is in the Small Magellanic Cloud, a satellite galaxy of the Milky Way that lies 200,000 light-years away in the constellation Tucana. The Small Magellanic Cloud is less rich in elements heavier than helium — what astronomers call metals — than the Milky Way. This makes conditions in the galaxy similar to what existed in the early universe.
NGC 346 is home to more than 2,500 newborn stars. The cluster’s most massive stars, which are many times more massive than our Sun, blaze with an intense blue light in this image. The glowing pink nebula and snakelike dark clouds are sculpted by the luminous stars in the cluster.
Hubble’s exquisite sensitivity and resolution were instrumental in uncovering the secrets of NGC 346’s star formation. Using two sets of observations taken 11 years apart, researchers traced the motions of NGC 346’s stars, revealing them to be spiraling in toward the center of the cluster. This spiraling motion arises from a stream of gas from outside of the cluster that fuels star formation in the center of the turbulent cloud.
The inhabitants of this cluster are stellar sculptors, carving out a bubble within the nebula. NGC 346’s hot, massive stars produce intense radiation and fierce stellar winds that pummel the billowing gas of their birthplace, dispersing the surrounding nebula.
The nebula, named N66, is the brightest example of an H II (pronounced ‘H-two’) region in the Small Magellanic Cloud. H II regions are set aglow by ultraviolet light from hot, young stars like those in NGC 346. The presence of this nebula indicates the young age of the star cluster, as an H II region shines only as long as the stars that power it — a mere few million years for the massive stars pictured here.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Image: This new image from the NASA/ESA Hubble Space Telescope showcases NGC 346, a dazzling young star cluster in the Small Magellanic Cloud. The Small Magellanic Cloud is a satellite galaxy of the Milky Way, located 210 000 light-years away in the constellation Tucana. The Small Magellanic Cloud is less rich in elements heavier than helium — what astronomers call metals — than the Milky Way. This makes conditions in the galaxy similar to what existed in the early Universe.
Although several images of NGC 346 have been released previously, this view includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.
NGC 346 is home to more than 2500 newborn stars. The cluster’s most massive stars, which are many times more massive than our Sun, blaze with an intense blue light in this image. The glowing pink nebula and snakelike dark clouds are the remnant of the birthplace of the stars in the cluster.
The inhabitants of this cluster are stellar sculptors, carving out a bubble from the nebula. NGC 346’s hot, massive stars produce intense radiation and fierce stellar winds that pummel the billowing gas of their birthplace and begin to disperse the surrounding nebula.
The nebula, named N66, is the brightest example of an H II (pronounced ‘H-two’) region in the Small Magellanic Cloud. H II regions are set aglow by ultraviolet light from hot young stars like those in NGC 346. The presence of the brilliant nebula indicates the young age of the star cluster, as an H II region shines only as long as the stars that power it — a mere few million years for the massive stars pictured here.

The cluster is made up of bright blue stars that illuminate the nebula around them. Large arcs of dense dust curve around, before and behind the clustered stars, pressed together by the stars’ radiation. Behind the clouds of the nebula can be seen large numbers of orange stars.]

NASA astronaut Christopher Williams poses for a portrait at NASA’s Johnson Space Center in Houston, Texas.Credit: NASA NASA astronaut Chris Williams will embark on his first mission to the International Space Station, serving as a flight engineer and Expedition 74 crew member.
Williams will launch aboard the Roscosmos Soyuz MS-28 spacecraft in November, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. After launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory.
During his expedition, Williams will conduct scientific investigations and technology demonstrations that help prepare humans for future space missions and benefit humanity.
Selected as a NASA astronaut in 2021, Williams graduated with the 23rd astronaut class in 2024. He began training for his first space station flight assignment immediately after completing initial astronaut candidate training.
Williams was born in New York City, and considers Potomac, Maryland, his hometown. He holds a bachelor’s degree in Physics from Stanford University in California and a doctorate in Physics from the Massachusetts Institute of Technology in Cambridge, where his research focused on astrophysics. Williams completed Medical Physics Residency training at Harvard Medical School in Boston. He was working as a clinical physicist and researcher at the Brigham and Women’s Hospital in Boston when he was selected as an astronaut.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to more fully focus its resources on deep space missions to the Moon and Mars.
