OBJECT
NGC 1511 is a spiral galaxy located in the constellation Aquarius. The measured velocity relative to cosmological space is 1,331 ± 5 km/s, corresponding to a Hubble distance of 19.6 ± 1.4 Mpc (∼63.9 million ly). It was discovered in 1834 by the British astronomer John Herschel. NGC 1511 is of type SB(s). NGC 1511 presents a large number of HI regions. Supernova SN 1935C was discovered in NGC 1524 on August 16 by American astronomer Emily Hughes Boyce7. The type of this supernova has not yet been determined. NGC 1511 is the largest and most brilliant galaxy of a trio of galaxies that bears its name. The other two galaxies in the group are NGC 1511, NGC 1473 and NGC 1511A (PGC 14255). In addition, the galaxy NGC 1511 is located in the same region of space as the galaxies NGC 1511A (ESO 55-5) and NGC 1511B (ESO 55-6).

Very interesting, Jac!

NGC 1511 appears to be one of those galaxies that undergo a burst of star formation near their centers, even though their visible outer regions are yellow, old and smooth. I found this picture of it by The Carnegie-Irvine Galaxy Survey:

---

You can see the active gas and dust-rich inner disk (or ring?) of NGC 1511, surrounded by a relatively large, smooth envelope. There are several galaxies with active interiors and smooth envelopes:

And there is the remarkable NGC 4314:

---

Note that NGC 4314 is a very well-formed grand design barred spiral galaxy that is completely "red and dead", except for a tiny ring surrounding its core!


And of course, there is the "mother of all central starburst galaxies", M82!

Cool ThanX Ann 4 your comments!

For me the faint arc in the circle is also a very interesting feature.
The question also arises as to which object is the cause of the large hole in NGC1511's lower arm, which only becomes fully visible in the IR-range of JWST.

I would guess that the elongated faint feature next to NGC 1511 is a stellar stream, somewhat similar to what is seen surrounding NGC 5907:

The hole in one of the arms of NGC 1511 is more mysterious, but it reminds me at least a little of some of the dark holes in M74 that were revealed by JWST:

MACS J0138.0-2155

Congratulation - Great processing!

"...James Webb took some images of the galaxy cluster MACS J0138.0-2155. This cluster is so massive that it distorts the light coming from behind it so strongly, we see it as a smudged stain. A phenomena caused by this effect is the cluster magnifies the light coming from behind it, like a magnifying glass. A research group used Webb to observe this cluster using its near infrared camera (NIRCam). They chose this instrument because the distorted light is so distant (a few billion light years away from us), and it gest redshifted. Webb's great sensitivity in infrared light is perfect for such mission. The main reason this group proposed this observation was to study a very distant supernova candidate. According to the group, this object is seen 5 times(!) in the image, due to the strong gravitational lensing and has a redshift of z=1.95, which translated to over 7 billion light years away. In addition, this object is in a galaxy the contains another lensed supernova (SN Requiem). Therefore, they named the supernova "Encore"." https://www.reddit.com/user/JwstFeedOfficial/

If confirmed, this will be the first time in history we observed a system that produced more than one lensed supernova.

Spiral galaxy NGC 4254's dazzling swirls

It's oh-so-easy to be mesmerized by this spiral galaxy. Follow its clearly defined arms, which are brimming with stars, to its center, where there may be old star clusters and—sometimes—active supermassive black holes. NASA's James Webb Space Telescope delivered highly detailed scenes of this and other nearby spiral galaxies in a combination of near- and mid-infrared light.

"NGC 4254, a spiral galaxy, is resplendent in orange and blue in this Jan. 29, 2024, image from the James Webb Space Telescope. [...] Webb's Near-Infrared Camera captured millions of stars in these images, which sparkle in blue tones, while the telescope's Mid-Infrared Instrument data highlights glowing dust, showing us where it exists around and between stars."

Peering Into the Tendrils of NGC 604 With NASA’s Webb

This image from Webb’s NIRCam (Near-Infrared Camera) of star-forming region NGC 604 shows how stellar winds from bright, hot, young stars carve out cavities in surrounding gas and dust. Credit: NASA, ESA, CSA, STScI

---

A well-studied hotbed of star formation is revealed in new detail by two of the telescope’s instruments, including MIRI, which was managed through launch by JPL. The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA’s James Webb Space Telescope.

Two new images from Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) showcase star-forming region NGC 604, located in the Triangulum galaxy (M33), 2.73 million light-years away from Earth. In these images, cavernous bubbles and stretched-out filaments of gas etch a more detailed and complete tapestry of star birth than seen in the past.

Webb probes an extreme starburst galaxy

The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments, as seen by Webb, are the polycyclic aromatic hydrocarbon emission, which traces the shape of the galactic wind. NASA, ESA, CSA, STScI, A. Bolatto (University of Maryland).

A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.

" [...] One area of focus for this research team was understanding how this galactic wind, which is caused by the rapid rate of star formation and subsequent supernovae, is being launched and influencing its surrounding environment. By resolving a central section of M82, scientists could examine where the wind originates, and gain insight on how hot and cold components interact within the wind. [...]"

So interesting, Jac! NGC 3972 is a relatively blue galaxy with a good amount of star formation. Its B-V index is 0.66, and its U-B index is —0.04. This is rather blue for a galaxy, whose "average" B-V index might be closer to 0.70 to 0.75 and its U-B index might be closer to, say, +0.10. NGC 3972 is somewhat brighter in the far infrared than at B wavelengths, which is a sign of healthy star formation. And indeed, the HST(?) image looks very dusty, and there are a lot of blue stars there. In fact, the HST image looks somewhat chaotic.

How different is the JWST image! We see the elegant "backbone" of the galaxy, the mass concentration in the form of billions of cool low-mass stars in the well-formed arms.

The blue fluff and chaotic dust of NGC 3972.

Fantastic! It is as if the small red stars are the "cake" of NGC 3972, and the starry blue fluff and all the dust is just the icing of the cake!
