ESA/Webb, NASA & CSA, A. Scholz, K. Muzic, A. Langeveld, R. Jayawardhana NASA’s James Webb Space Telescope has infrared vision that lets us peer through the dusty veil of nearby star-forming region NGC 1333. We can see planetary mass objects, newborn stars, and brown dwarfs; some of the faintest ‘stars’ in this mosaic image are in fact newly born free-floating brown dwarfs with masses comparable to those of giant planets. The images were captured as part of a Webb observation program to survey a large portion of NGC 1333. These data constitute the first deep spectroscopic survey of the young cluster.

Technicians test a set of massive solar arrays measuring about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high for NASA’s Europa Clipper spacecraft inside the agency’s Payload Hazardous Servicing Facility at Kennedy Space Center in Florida on Aug. 7.Credits: NASA/Kim Shiflett NASA and SpaceX are targeting a launch period opening Thursday, Oct. 10, for the agency’s Europa Clipper mission, which will help scientists determine if one of Jupiter’s icy moons could support life. The mission will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Europa Clipper will carry nine instruments and a gravity science experiment aboard to gather detailed measurements as it orbits Jupiter and conducts multiple close flybys of its moon, Europa. Research suggests an ocean twice the volume of all of Earth’s oceans exists under Europa’s icy crust.
Media interested in covering the Europa Clipper launch must apply for media accreditation. Deadlines for accreditation are as follows:
U.S. citizens representing domestic or international media must apply for accreditation by 11:59 p.m. EDT, Friday, Sept. 27. International media without U.S. citizenship must apply by 11:59 p.m., Friday, Sept. 20. Media requiring special logistical arrangements, such as space for satellite trucks, tents, or electrical connections, should email ksc-media-accreditat@mail.nasa.gov by Tuesday, Oct. 1.
A copy of NASA’s media accreditation policy is available online. For questions about accreditation, please email: ksc-media-accreditat@mail.nasa.gov. For other mission questions, please contact NASA Kennedy’s newsroom at 321-867-2468.
Para obtener información sobre cobertura en español en el Centro Espacial Kennedy o si desea solicitar entrevistas en español, comuníquese con Antonia Jaramillo: 321-501-8425, o Messod Bendayan: 256-930-1371.
Accredited media will have the opportunity to participate in a series of prelaunch briefings and interviews with key mission personnel, including a briefing the week of Sept. 9. NASA will communicate additional details regarding the media event schedule as the launch date approaches.
NASA also will post updates on spacecraft launch preparations on NASA’s Europa Clipper blog.
Clipper’s primary science goal is to determine whether there are places below the surface of Europa that could support life. The mission’s three main science objectives are to understand the nature of the ice shell and the ocean beneath it, along with the moon’s composition and geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory in Southern California leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA Headquarters in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft.

Hubble Captures Unique Ultraviolet View of a Spectacular Star Cluster
NASA, ESA, and C. Murray (Space Telescope Science Institute); Image Processing: Gladys Kober (NASA/Catholic University of America) Roughly 210,000 light-years away, the Small Magellanic Cloud (SMC) is one of our Milky Way galaxy’s closest neighbors. In fact, this small galaxy is one of the Milky Way’s “satellite” galaxies, which orbit our home spiral galaxy.
Nested within the SMC is this spectacular star cluster, known as NGC 346. Its hot stars unleash a torrent of radiation and energetic outflows, which erode the denser portions of gas and dust in the surrounding nebula, N66. Dozens of hot, blue, and high-mass stars shine within NGC 346, and astronomers believe this cluster contains more than half of the known high-mass stars in the whole SMC.
This inset image shows the location of NGC 346 within the Small Magellanic Cloud. NASA, ESA, C. Murray (Space Telescope Science Institute), and ESO/VISTA VMC; Image Processing: Gladys Kober (NASA/Catholic University of America) The NASA/ESA Hubble Space Telescope has observed this cluster before, but its new view shows NGC 346 in ultraviolet light, along with some visible-light data. Ultraviolet light helps scientists understand more about star formation and evolution, and Hubble – with its combined sharp resolution and position above our UV-blocking atmosphere – is the only telescope with the ability to make sensitive, ultraviolet observations.
These two Hubble images of NGC 346 show the star cluster in visible and ultraviolet wavelengths of light. NASA, ESA, A. James (STScI), and C. Murray (Space Telescope Science Institute); Image Processing: Gladys Kober (NASA/Catholic University of America) These specific observations were gathered to learn more about how star formation shapes the interstellar medium, which is the gas distributed throughout seemingly empty space, in a low-metallicity galaxy like the SMC. Astronomers call elements heavier than hydrogen and helium “metals,” and the SMC contains fewer metals when compared to most parts of our Milky Way. This condition helps make it an excellent example of a galaxy similar to those that existed in our early universe, when very few heavy elements were around to incorporate.

ESA/Hubble & NASA, I. Chilingari The subject of this NASA/ESA Hubble Space Telescope image is situated in the Perseus Cluster, also known as Abell 426, 320 million light-years from Earth. It’s a barred spiral galaxy known as MCG+07-07-072, seen here among a number of photobombing stars that are much closer to Earth than it is.
MCG+07-07-072 has quite an unusual shape for a spiral galaxy, with thin arms emerging from the ends of its barred core to draw a near-circle around its disk. It is classified as an SBc(r) galaxy: the c denotes that its two spiral arms are loosely wound, each only performing a half-turn around the galaxy, and the (r) is for the ring-like structure they create.
Rings in galaxies come in quite a few forms, from merely uncommon, to rare and scientifically important! Lenticular galaxies are a type that sit between elliptical and spiral galaxies. They feature a large disk, unlike an elliptical galaxy, but lack any spiral arms. Lenticular means lens-shaped, and these galaxies often feature ring-like shapes in their disks.
Meanwhile, the classification of “ring galaxy” is reserved for peculiar galaxies with a round ring of gas and star formation, much like spiral arms look, but completely disconnected from the galactic nucleus — or even without any visible nucleus! They’re thought to be formed in galactic collisions. Finally, there are the famous gravitational lenses, where the ring is in fact a distorted image of a distant, background galaxy, formed by the ‘lens’ galaxy bending light around it. Ring-shaped images, called Einstein rings, only form when the lensing and imaged galaxies are perfectly aligned.
