ESA/Hubble & NASA, R. Windhorst, W. Keel This NASA/ESA Hubble Space Telescope image features a spiral galaxy, named UGC 10043. We don’t see the galaxy’s spiral arms because we are seeing it from the side. Located roughly 150 million light-years from Earth in the constellation Serpens, UGC 10043 is one of the somewhat rare spiral galaxies that we see edge-on.
This edge-on viewpoint makes the galaxy’s disk appear as a sharp line through space, with its prominent dust lanes forming thick bands of clouds that obscure our view of the galaxy’s glow. If we could fly above the galaxy, viewing it from the top down, we would see this dust scattered across UGC 10043, possibly outlining its spiral arms. Despite the dust’s obscuring nature, some active star-forming regions shine out from behind the dark clouds. We can also see that the galaxy’s center sports a glowing, almost egg-shaped ‘bulge’, rising far above and below the disk. All spiral galaxies have a bulge similar to this one as part of their structure. These bulges hold stars that orbit the galactic center on paths above and below the whirling disk; it’s a feature that isn’t normally obvious in pictures of galaxies. The unusually large size of this bulge compared to the galaxy’s disk is possibly due to UGC 10043 siphoning material from a nearby dwarf galaxy. This may also be why its disk appears warped, bending up at one end and down at the other.
Like most full-color Hubble images, this image is a composite, made up of several individual snapshots taken by Hubble at different times, each capturing different wavelengths of light. One notable aspect of this image is that the two sets of data that comprise this image were collected 23 years apart, in 2000 and 2023! Hubble’s longevity doesn’t just afford us the ability to produce new and better images of old targets; it also provides a long-term archive of data which only becomes more and more useful to astronomers.

For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and ‘weighed’ a galaxy, in the early Universe, that has a mass that is similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Found at around 600 million years after the Big Bang, this lightweight galaxy, nicknamed the Firefly Sparkle, is gleaming with star clusters – 10 in total – that researchers examined in great detail. Other galaxies Webb has detected at this period in the history of the Universe are significantly more massive.

Launched in May 2024, ESA’s EarthCARE satellite is nearing the end of its commissioning phase with the release of its first data on clouds and aerosols expected early next year. In the meantime, an international team of scientists has found an innovative way of applying artificial intelligence to other satellite data to yield 3D profiles of clouds.
This is particularly news for those eagerly awaiting data from EarthCARE in their quest to advance climate science.

NASA’s SPHEREx observatory undergoes integration and testing at BAE Systems in Boulder, Colorado, in April 2024. The space telescope will use a technique called spectroscopy across the entire sky, capturing the universe in more than 100 colors. BAE Systems Registration is open for digital content creators to attend the launch of NASA’s Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission, and NASA’s Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission. SPHEREx will provide the first all-sky spectral survey, collecting data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe. PUNCH is a constellation of four small satellites in low-Earth orbit that will make global, 3D observations of the Sun’s corona to learn how the mass and energy there become solar wind.
NASA and SpaceX are targeting no earlier than February 2025 for the SPHEREx and PUNCH missions launch on a SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Space Force Base in California.
If your passion is to communicate and engage the world online, then this is the event for you! Seize the opportunity to see and share the SPHEREx and PUNCH missions’ launch.
A maximum of 50 social media users will be selected to attend this one-day event and will be given access similar to news media.
NASA Social participants will have the opportunity to:
View the launch of the SPHEREx and PUNCH satellites on a SpaceX Falcon 9 rocket. Tour NASA facilities at Vandenberg Space Force Base. Meet and interact with SPHEREx and PUNCH subject matter experts. Meet fellow space enthusiasts who are active on social media. NASA Social registration for the SPHEREx and PUNCH launch opens on Monday, Dec. 9, and the deadline to apply is Monday, Dec. 23 at noon ET. All social applications will be considered on a case-by-case basis.

How do I register?
Registration for this event opens Monday, Dec. 9, and closes Monday, Dec. 23 at noon ET. Registration is for one person only (you) and is nontransferable. Each individual wishing to attend must register separately. Each application will be considered on a case-by-case basis.
Can I register if I am not a U.S. citizen?
Because of the security restrictions on the Space Force base, registration is limited to U.S. citizens. If you have a valid permanent resident card, you will be processed as a U.S. citizen.
When will I know if I am selected?
After registrations have been received and processed, an email with confirmation information and additional instructions will be sent to those selected. We expect to send the acceptance notifications by Jan. 31.
What are NASA Social credentials?
All social applications will be considered on a case-by-case basis. Those chosen must prove through the registration process that they meet specific engagement criteria.
If you do not make the registration list for this NASA Social, you still can attend the launch offsite and participate in the conversation online.
What are the registration requirements?
