Zamani (ESA/Hubble) This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celestial lights. Like any spiral galaxy, shining stars fill its disk, giving the galaxy a beautiful glow. Along its two large arms, bubbles of hydrogen gas shine in a striking red light fueled by radiation from infant stars shrouded within. Near the galaxy’s center are some particularly spectacular stars embedded within a ring of hot gas. These newly formed and extremely hot stars emit powerful X-rays. Closer in, at the galaxy’s very center, sits an even brighter source of X-rays, an active galactic nucleus. This X-ray powerhouse makes NGC 1672 a Seyfert galaxy. It forms as a result of heated matter swirling in the accretion disk around NGC 1672’s supermassive black hole.

This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado.

It forms as a result of heated matter swirling in the accretion disk around NGC 1672’s supermassive black hole.
Image Before/After Along with its bright young stars and X-ray core, a highlight of this image is the most fleeting and temporary of lights: a supernova, visible in just one of the six Hubble images that make up this composite. Supernova SN 2017GAX was a Type I supernova caused by the core-collapse and subsequent explosion of a giant star that went from invisible to a new light in the sky in just a matter of days. In the image above, the supernova is already fading and is visible as a small green dot just below the crook of the spiral arm on the right side. Astronomers wanted to look for any companion star that the supernova progenitor may have had — something impossible to spot beside a live supernova — so they purposefully captured this image of the fading supernova.
Recently, NGC 1672 was also among a crop of galaxies imaged with the NASA/ESA/CSA James Webb Space Telescope, showing the ring of gas and the structure of dust in its spiral arms. The image below compares the Webb image with Hubble’s image.

NASA, ESA, CSA, STScI Stare deeply at these galaxies. They appear as if blood is pumping through the top of a flesh-free face. The long, ghastly “stare” of their searing eye-like cores shines out into the supreme cosmic darkness.
It’s good fortune that looks can be deceiving.
These galaxies have only grazed one another to date, with the smaller spiral on the left, cataloged as IC 2163, ever so slowly “creeping” behind NGC 2207, the spiral galaxy at right, millions of years ago.
The pair’s macabre colors represent a combination of mid-infrared light from NASA’s James Webb Space Telescope with visible and ultraviolet light from NASA’s Hubble Space Telescope.

This observation combines mid-infrared light from NASA’s James Webb Space Telescope, and ultraviolet and visible light from NASA’s Hubble Space Telescope. The galaxies grazed one another millions of years ago. The smaller spiral on the left, cataloged as IC 2163, passed behind NGC 2207, the larger spiral galaxy at right. NASA, ESA, CSA, STScI Look for potential evidence of their “light scrape” in the shock fronts, where material from the galaxies may have slammed together. These lines represented in brighter red, including the “eyelids,” may cause the appearance of the galaxies’ bulging, vein-like arms.
The galaxies’ first pass may have also distorted their delicately curved arms, pulling out tidal extensions in several places. The diffuse, tiny spiral arms between IC 2163’s core and its far left arm may be an example of this activity. Even more tendrils look like they’re hanging between the galaxies’ cores. Another extension “drifts” off the top of the larger galaxy, forming a thin, semi-transparent arm that practically runs off screen.

This mid-infrared image from NASA’s James Webb Space Telescope excels at showing where the cold dust, set off in white, glows throughout these two galaxies, IC 2163 and NGC 2207. The telescope also helps pinpoint where stars and star clusters are buried within the dust. These regions are bright pink. Some of the pink dots may be extremely distant active supermassive black holes known as quasars. NASA, ESA, CSA, STScI Both galaxies have high star formation rates, like innumerable individual hearts fluttering all across their arms. Each year, the galaxies produce the equivalent of two dozen new stars that are the size of the Sun. Our Milky Way galaxy only forms the equivalent of two or three new Sun-like stars per year. Both galaxies have also hosted seven known supernovae in recent decades, a high number compared to an average of one every 50 years in the Milky Way. Each supernova may have cleared space in their arms, rearranging gas and dust that later cooled, and allowed many new stars to form.
To spot the star-forming “action sequences,” look for the bright blue areas captured by Hubble in ultraviolet light, and pink and white regions detailed mainly by Webb’s mid-infrared data. Larger areas of stars are known as super star clusters. Look for examples of these in the top-most spiral arm that wraps above the larger galaxy and points left. Other bright regions in the galaxies are mini starbursts — locations where many stars form in quick succession. Additionally, the top and bottom “eyelid” of IC 2163, the smaller galaxy on the left, is filled with newer star formation and burns brightly.
Image C: Galaxies IC 2163 and NGC 2207 (Hubble and Webb Images Side by Side)
Image Before/After What’s next for these spirals? Over many millions of years, the galaxies may swing by one another repeatedly. It’s possible that their cores and arms will meld, leaving behind completely reshaped arms, and an even brighter, cyclops-like “eye” at the core. Star formation will also slow down once their stores of gas and dust deplete, and the scene will calm.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
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, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Hubble Captures a New View of Galaxy M90
This eye-catching image offers us a new view of the spiral galaxy Messier 90 from the NASA/ESA Hubble Space Telescope. ESA/Hubble & NASA, D. Thilker, J This NASA/ESA Hubble Space Telescope image features the striking spiral galaxy Messier 90 (M90, also NGC 4569), located in the constellation Virgo. In 2019, Hubble released an image of M90 created with Wide Field and Planetary Camera 2 (WFPC2) data taken in 1994, soon after its installation. That WFPC2 image has a distinctive stair-step pattern due to the layout of its sensors. Wide Field Camera 3 (WFC3) replaced WFPC2 in 2009 and Hubble used WFC3 when it turned its aperture to Messier 90 again in 2019 and 2023. That data resulted in this stunning new image, providing a much fuller view of the galaxy’s dusty disk, its gaseous halo, and its bright core.
The inner regions of M90’s disk are sites of star formation, seen here in red H-alpha light from nebulae. M90 sits among the galaxies of the relatively nearby Virgo Cluster, and its orbit took M90 on a path near the cluster’s center about three hundred million years ago. The density of gas in the inner cluster weighed on M90 like a strong headwind, stripping enormous quantities of gas from the galaxy and creating the diffuse halo we see around it. This gas is no longer available to form new stars in M90, with the spiral galaxy eventually fading as a result.
M90 is located 55 million light-years from Earth, but it’s one of the very few galaxies getting closer to us. Its orbit through the Virgo cluster has accelerated so much that M90 is in the process of escaping the cluster entirely. By happenstance, it’s moving in our direction. Astronomers have measured other galaxies in the Virgo cluster at similar speeds, but in the opposite direction. As M90 continues to move toward us over billions of years, it will also be evolving into a lenticular galaxy.
