The James Webb Space Telescope (JWST) has done it again. On June 3, 2025, NASA released a brand-new image of the Sombrero Galaxy. This time, the galaxy was captured using JWST’s Near-Infrared Camera (NIRCam). The image is breathtaking. But more importantly, it offers fresh scientific insights. This spiral galaxy, also known as Messier 104 or NGC 4594, lies about 30 million light-years away in the Virgo constellation. It’s one of the most iconic galaxies in the night sky. And thanks to JWST, we’re now seeing it in a whole new light, literally.
A quick look at the Sombrero galaxy
The Sombrero Galaxy earned its name because of how it looks. It resembles a wide-brimmed Mexican hat. A bright central bulge forms the “crown.” A thick lane of dust forms the “brim.” This classic edge-on spiral galaxy is 50,000 light-years across. That’s roughly half the size of the Milky Way. But it shines with the light of 800 billion Suns. Astronomers have studied it for decades. It has a huge central bulge. It has a very pronounced dust ring. And it possibly hosts a supermassive black hole in the center.
The power of NIRCam
JWST’s Near-Infrared Camera (NIRCam) looks at light just beyond the visible range. This infrared light can penetrate gas and dust. That’s why NIRCam is perfect for peeking into the hidden parts of galaxies.
In the new image, NIRCam reveals the Sombrero’s bright inner bulge clearly. You can see tightly packed stars that make up the galactic core. The outer ring of dust stands out in stark contrast. This image complements earlier ones taken with JWST’s Mid-Infrared Instrument (MIRI).
Comparing NIRCam and MIRI views
In 2024, JWST captured the Sombrero using MIRI, which sees in longer infrared wavelengths. That image showed cooler parts of the galaxy, mainly the dust ring. The MIRI image made the inner bulge appear fainter. That’s because MIRI doesn’t pick up strong light from older stars. But it beautifully highlighted cold dust clouds.
In contrast, NIRCam reveals hot stars and the structure of the bulge. The stars look brighter. The central region pops out. And the dust in the ring becomes more of an absorbing layer. So together, the NIRCam and MIRI images tell a fuller story. We get a multi-layered view of the galaxy’s structure. Astronomers can study both the stellar population and dust dynamics.
The mystery of the bulge
The Sombrero Galaxy’s bulge is unusually large for a spiral galaxy. It resembles the bulge of an elliptical galaxy. This has puzzled astronomers. Some scientists believe the Sombrero may be a hybrid—a spiral galaxy with the core of an elliptical. Others think it may have merged with another galaxy long ago. The new NIRCam image adds more clues. It shows that the bulge is filled with older stars, densely packed. It may also host a supermassive black hole, as large as one billion solar masses, based on earlier X-ray studies. JWST’s data could help measure the bulge’s stellar population more precisely.
A look back: Hubble’s view
Before JWST, the Hubble Space Telescope gave us some of the most famous images of the Sombrero Galaxy. In 2004, Hubble captured the galaxy in visible light using its Advanced Camera for Surveys (ACS). That image became iconic. Hubble showed the galaxy’s bright core, dark dust ring, and smooth halo. It revealed sharp edges and fine dust lanes, but only what was visible in optical wavelengths.
While beautiful, Hubble’s view couldn’t penetrate the dust. It showed what was on the surface, not what was inside. That’s where JWST makes the difference.
JWST’s new view of the Sombrero Galaxy is not just a pretty picture. It’s a scientific breakthrough. It shows us how dust, stars, and structure come together in a spiral galaxy. It peels back layers of gas to reveal hidden features. And it connects us to a galaxy that may hold clues about our own Milky Way’s future. With every new image, JWST continues to change how we see the universe. And the best part? This is just the beginning.
Clear skies!
