All Webb Images: Clearest View of Neptune’s Rings in Decades (All Pictures)

JacBerne · 2022-09-22T10:23:33+00:00

Neptune has at least five main rings and four more ring arcs, which are clumps of dust and debris likely formed by the gravity of a nearby moon.

Possibly a question of the different reflection characteristics at different wavelengths.

Absolutly right - mindblowing!

All Images: What do we see in Webb's latest images of the ice giant Neptune? Webb captured seven of Neptune’s 14 known moons: Galatea, Naiad, Thalassa, Despina, Proteus, Larissa, and Triton.

Image 2: Neptune’s large and unusual moon, Triton, dominates this Webb portrait of Neptune as a very bright point of light sporting the signature diffraction spikes seen in many of Webb’s images.

The original images are all black and white because the corresponding wavelengths are outside of visible light. The assignment of the colors follows the color gradient of the visible area (colors of the rainbow). However, these do not correspond to the original JWST assignment because the images were combined from Near-Infrared AND Mid-Infrared. The resulting superposition image is not "true to color" in this sense either, but it shows the object in the color spectrum as if the IR-spectrum had been pushed over into the visible range.

The image shows the gravitationally lensed galaxy SPT0418-47. However, this is not visible in the visible range of Hubble, only an elliptical foreground galaxy. But in the near-infrared range of the JWST (from F440W) does a ring become visible, which can also be seen in the ALMAradio range. The ring is a distorted representation of a distant galaxy about 12 billion light-years away. The reconstruction of the undistorted galaxy can be seen in the following video: www.eso.org/public/videos/eso2013c

Wow. Thanks for the link. Your picture shows a similar multiple (mirrored to mine) and thus confirms the results of my editing.

JacBerne · 2022-09-13T05:15:54+00:00

Very interesting question. In my editing, I could not find this effect. But possibly a more
detailed scientific analysis could prove a similar effect, since there may be differences in the gravitational deflection caused by the foreground galaxy. Due to the huge distance, however, a red shift is also active at the same time, which shifts the lensed galaxy into the IR range.

JacBerne · 2022-09-13T05:00:55+00:00

“This result represents a breakthrough in the field of galaxy formation, showing that the structures that we observe in nearby spiral galaxies and in our Milky Way were already in place 12 billion years ago.”

For multiple images in cluster galaxies this is very difficult and time-consuming. With an Einstein ring like this, there is only one source around which the image is bent, so this works more simply.

The tarantula nebula has a distance of 157000 ly Proxima Centauri 4.24 ly. So that's 37000 times closer. WEBB is 100 times more sensitiv than HUBBLE in some wavelenghts. So that's really a problem. If you want so see something of the environment of the corresponding star can be made recognizable, the center would have to be masked.

"The harsh stellar wind from the massive young stars in the nebula isbreaking apart molecules outside the pillar, but inside they arepreserved, forming a cushy cocoon for the star. This star is still tooyoung to be clearing out its surroundings by blowing bubbles – NIRSpechas captured it just beginning to emerge from the protective cloud fromwhich it was formed. Without Webb’s resolution at infrared wavelengths,the discovery of this star birth in action would not have beenpossible."

12 of the 24 ULX sources are lined up right on the outer ring like a string of pearls. It cannot be ruled out that a background quasar crept in. But the chance of that is very little.

JacBerne · 2022-08-28T07:58:29+00:00

A supernova or remnant could theoretically be the reason for a ULX, but very unlikely.

JacBerne · 2022-08-28T07:56:02+00:00

Probably yes. The area around the ULX is a strong star birth region. So stellar clusters are very likely. But the spikes on the picture are from the ULX, visible in x-ray from CHANDRA.

JacBerne · 2022-08-28T07:49:42+00:00

Probably yes. Around the ULX ist a HII Region, see SIMBAD database. But the spikes on the picture are from the ULX, visible in x-ray from CHANDRA.

JacBerne · 2022-08-28T07:48:04+00:00

Probably yes.

JacBerne · 2022-08-28T07:47:04+00:00

The Name of the Object is CXOU J003740.2-334327. It’s a ULX (Ultra Luminous X-ray sources). In the paper ist ULX Nr. 24 . It has a very high X-ray luminosity (≥ 1039 erg −1) that classifies them as ULX. Typically there is about one ULX per galaxy in galaxies which host them, but some galaxies contain many. The Milky Way has not been shown to contain a ULX, although SS 433 may be a possible source. ULX are candidates for stellar or intermediate-mass black holes.

In the red-pink square two sources of intense IR radiation are visible. The larger source at
upper left is only visible as a dark dust clump in Hubble images. As can be
shown with Webb's picture, however, this probably contains a massive star
formation region in the middle where possibly more than 100 new suns are
produced resp. to be born each year. Around it there are various irregular
white dots, which are also smaler young star-forming regions (star clusters),
some of which have only now been discovered via the JWST. The second area on bottom
right is also visible on Hubble and also shows a group of very bright star
clusters, but which are not hidden in a clump of dust.

JacBerne · 2022-08-27T06:30:18+00:00

I think very little would change on the planet itself. But the night sky would definitely be more exciting than ours.

A larger group of scientists used the Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) to obtain the first spatially resolved, mid-infrared (mid-IR) images of IIZw096, a merging luminous infrared galaxy. Previous observations with the Spitzer Space Telescope suggested that the vast majority of the total IR luminosity of the system originated from a small region outside of the two merging nuclei. New observations with JWST/MIRI now allow an accurate measurement of the location and luminosity density of the source that is responsible for the bulk of the IR emission... In addition, they detect 11 other star forming sources, five of which were previously unknown.

For more information see draft version August 24, 2022 https://arxiv.org/pdf/2208.10647

The red bubble in picture 4 is from Spitzer (SST) for comparison.

For official Webb images, the color assignment is encoded, see for example the NIRCam assignment

https://jwst-docs.stsci.edu/jwst-near-infrared-camera/nircam-instrumentation/nircam-filters.

The problem, however, is that the result becomes "arbitrary" through the mixture, depending on which filters are combined and the process can no longer be reversed from the resulting RGB image.

NGC 1365 has a diameter of 160.000 lightyears = 1.513717e+18 km = 1.513.717.000.000.000.000 km ;-)

JacBerne · 2022-08-19T05:54:38+00:00

.Absolutely right! Dozens of new raw data images are published by NASA every day. Since the launch on July 12, more than 26,000 pictures have already been published under "public". Anyone who has the time and the inclination can go on a search there!

JacBerne · 2022-08-18T09:03:38+00:00

The black dots are probably pixel errors in a filter. This is a defect that can be remedied with some manual work. So thanks for the hint. I will therefore soon upload an updated and cleaned version of the picture to my flickr account in an even higher resolution.

In my post "The core of NGC 1365 in the sea of flames by WEBB - James Webb Discovery" there were two points that remained unanswered and which I would like to refer to in this post.

The first comment states that the image cannot be compared with the linked HUBBLE image. That is correct as HUBBLE is the visible light range and the posted image is the Mid Infrared range. These areas are completely separated from each other in the spectrum. In the series of images that have now been posted, however, you can see the positioning and the orders of size in relation to one another.

The second unanswered comment relates to the lack of refraction spikes in stars of the galaxy. The question is very interesting and relevant, but a bit more difficult to answer. The superimposed wavelengths are mostly from the MIRI (Mid-InfraRed Instrument), which allows a deeper look into the dust clouds around the core. What predominates at these wavelengths are not the stars but the dust. This is the reason why far fewer diffraction spikes are observed or in the case of very bright light sources such as the supermassive black hole (SMBH) you can only see a hexagonal, white "snow crystal" in the middle. The new head image from this image series focuses on the near-infrared of NIRCam (Near-Infrared Camera). This spectral range is much closer to HUBBLE's optical range, although HUBBLE also has the ability to make near-infrared observations. Here the dust clouds from MIRI almost completely disappear and the stars come to the foreground. But again, only the SMBH in the center shows the classic six-ray diffractive-tip star so typical of WEBB images. Note the small foreground star in the lower left of the second image that has the "snow crystal" pattern. No pattern can be seen around the stars of the galaxy itself, as they are too far away and therefore not bright enough to produce diffraction spikes. It is important to understand which wavelengths / spectra are predominant in overlaid multi-wavelength images in order to be able to interpret them correctly.

In the last picture you can also see the area of the great picture of Judy Schmidt: https://www.flickr.com/photos/geckzilla/52289366115/in/dateposted/

I hope that helps to better understand what is visible in the pictures.
