You're not gonna see pretty pictures like from the Hubble?
JWT is an infrared telescope!

Good to see you are over your fascination with female tits and suckling infants, but seemingly have adopted the other nuisance and his "pretty pictures" taunt.

Disregarding the 'big bang' overreach, the telescope will present a more detailed look at stellar evolution by having a more abundant range of choices.. It may be possible to create a better narrative of stellar evolution and the birth of a solar system considering that these events are still occurring and they have a specific geometry attached-

Now, that's not true. JWT isn't just going to do spectroscopy, it
_will_ do imaging. So the images will be in false colors, that
doesn't mean there won't be images.

But it will be looking out at distant stars and galaxies, mainly
in order to do astrophysics. No pictures of the planets or their
satellites, their rotation or orbits. That is why I would be inclined
to have expected the original poster to not be too interested.

A video I saw on YouTube included a picture from some random
web site where a game show contestant seemed to be having
trouble with the following question:

Which of these is a country:

Africa
Europe
London
Taiwan

The answer, of course, is "Taiwan", although if you're John Cena,
you might be hesitant to say so. (Africa and Europe are continents,
and London is a city.)

Anyways, I searched for the source of the image - and in looking for
it, I ran across the image on this page

https://americasbestpics.com/picture/eZ83dt3C9

which the original poster of this thread _really_ wouldn't like.

The imaging supplied by Webb with a greater range of objects to image will hopefully expand the narrative where some supernova events do not represent the demise of the antecedent star, but a redistribution of mass into the creation of a solar system and therefore a metamorphosis from one state to another.

http://www.sci-news.com/astronomy/science-remnant-supernova-sn1987a-02268.html

Our own star, due to the residual geometry of these events, may have gone through this process along with supporting pre-supernova and post-supernova imaging.

Yes, you will have to look at those pictures with a special
infrared viewer! Better buy one now, before they sell out:

It can still make monochrome intensity images or wavelength dependent
false colour images. Just like the Hubble and radio telescopes do.

One of the channels in many Hubble palette images SII is redder than
Halpha almost beyond wavelengths that human eyes are sensitive to.

Many Hubble images are in artificial colours by design.

I hope that unfurling the heat shield goes smoothly it is a very tricky
piece of origami to perform at a distance. It won't work without it!

Everything seems to be going as planned, thank God-

https://www.jwst.nasa.gov/content/webbLaunch/whereIsWebb.html

Good to see the major milestone of the sunshield deployed-

Thanks to those who are promoting the capability of the telescope in terms of imaging.

Someone else mentioned that pictures from the Hubble are usually
in the "Hubble Palette"; that is, monochrome _narrowband_ images
for three specific spectral lines are combined, with one each as R, G,
and B, to create a color image with exaggerated color.

Presumably, the same thing will be done with the Webb telescope
to form images.

The Hubble palette involves a red Sulfur II line assigned to R, a red
Hydrogen alpha line assigned to G, and a green Oxygen III line assigned
to B.

The gold-coated mirrors of the James Webb telescope will have no
problem reflecting red light, in addition to near infrared and far
infrared light.

The spectrum of Oxygen III does not just contain one line. There are
88,400 nm and 51,800 nm lines in the far infrared.

The Near Infrared camera is sensitive down to 600 nm. Both the
Hydrogen alpha line and the Sulfur II line are between 600 nm and
700 nm, so they are within its range. However, only broad-band
filters are noted as being included with the instrument.

The Mid-Infrared Instrument does imaging from 5,000 nm to 28,000 nm.
That will not be able to image using the Oxygen III lines I've noted.

I was wondering if it would be possible for the Webb telescope, by using
a different spectral line of Oxygen III, to "fake" a Hubble palette image.

Maybe if they can pick an epoch. Remember at serious cosmic distances
Lyman-alpha is a long way from where you might expect to see it!

This paper describes the Webb instrumentation in considerable detail.
