James Webb Space Telescope News

That depends on the field of view.

While true, the image in question does not show anything that can produce lensing.

Have you even gone to Webb's page about this? From the Webb site hosting this image:

"Bound together by gravity in a galaxy cluster, they are bending the light from galaxies that appear in the vast distances behind them. The combined mass of the galaxies and dark matter act as a cosmic telescope, creating magnified, contorted, and sometimes mirrored images of individual galaxies."

That's utter nonsense.

It sure isn't (see above).

Gravitational lensing does NOT produce distortion banding on a curved arc as shown in that photo.

Physics just doesn't work that way. Again, more investigation is needed.

Gee, thanks. I needed a wiki link for a subject I've been studying in detail for decades...

 

[the54thvoid]

NASA themselves are describing it as gravitational lensing. I'll accept their rational for now. And as a science subject, few members can out do NASA.

That was their public statement. There is some debate surrounding that image and for the reasons highlighted above. Believe what you want though...

Provide your evidence for the debate please. I'll gladly welcome scientific rigour.

EDIT: I found this, which discusses dark matter.

Here is a Hubble image of gravitational lensing (for comparison)

[Bomby569]

These are all infrared pictures with values attributed to make the colours you see, these are not what you'd see with your eyes. Also you can not see everything, not all black holes can be seen for example, not even with the JWST. You can not look at these pictures and assume you have all the information you need to say things like "there is nothing else there"

I think there are a lot of wrong assumptions here that make for some flawed conclusions.

I need help (no sarcastic replies please ;-)

I don't see what you are saying 'on a curved arc as shown'

Could you make it clearer? is it present on the Hubble picture?

I'm not seeing anything.

 

[lexluthermiester]

Provide your evidence for the debate please.

Already did. If the problem is not glaringly apparent, well that's a thing.

Well said.

No worries.

Ok let's look at your attached image...

See how the distortions are in symmetrical concentric circular forms, clearly inditcating a gravity source? This is the effect gravitational lensing has on a particular viewing arc.

Now lets look at the image from NASA...

Here, the distortions are do not show a pattern that can indicate a gravitational source, nor do they indicate potential multiple sources. The fore-ground stars show very minor indication of distortion and should be showing none in relation to the background objects being observed.

I don't know how to make this problem any more clear.

 

[the54thvoid]

This is the full Webb deep field image. It shows circular distortion.

From NASA:

Other features include the prominent arcs in this field. The powerful gravitational field of a galaxy cluster can bend the light rays from more distant galaxies behind it, just as a magnifying glass bends and warps images. Stars are also captured with prominent diffraction spikes, as they appear brighter at shorter wavelengths.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

It's the first thing I picked up on and mentioned in page one, I am not sure why but something is causing that effect.

No, this request is not about your opinion on this image, all of us have our different opinions.

What he means is post links to discussions between astronomers who are discussing the problem that you see here. You've indicated multiple times that there are people who see this anomaly and are exchanging ideas about it. Where are the scientific discussions between experts in the field about this? That's what we want you to post.

Clarification much appreciated.

Look at photos/videos of the actual satellite. NOVA featured Webb in an episode broadcasted right around the time when the first images from the satellite were unveiled to the public.

At least as impressive as the mirror array itself are other components that needed to unfurl/deploy for it to start its science mission.

Webb has no selfie camera so the only images and videos we have of it are those taken before its launch.

Seeing things like this just makes me think how small is a one human being in the whole universe. It just blows my mind and even a light year feels small as hell.
