I'm reading "The Lonely Work of Picking the Universe’s Best Astronomy Pictures/In June, specialists gathered in Baltimore to select images from the James Webb Space Telescope to share with the public. Keeping the results to themselves hasn’t been easy" by Joshua Sokol in the NYT.
In the new rationale, we don't get a flood of photographs. We get a slow succession of carefully chosen, heavily processed images.
The news media and politicians were invited to galas to see eagerly anticipated first glimpses of other planets, beamed back like postcards from sightseeing drives through the solar system. In this era, at the inception of digital imagery, engineers on missions like Voyager often experimented with combining multi-wavelength data into pictures with ultra-vivid hues, said Elizabeth Kessler, a historian of visual culture at Stanford. "They just look like throbbing, shifting, morphing, psychedelic colors," she said....
In 2016, a committee of representatives from the Space Telescope Science Institute, NASA and the European and Canadian space agencies convened to start choosing Webb’s very first demo targets. They checked off boxes that vibed with the telescope’s scientific goals: a deeper-than-ever deep field, galaxies pulsing in the void like jellyfish, a star with an attendant exoplanet, star-forming regions like the Carina Nebula and more....
Stars in Webb images have six points, unlike the four spikes common in most space photography, a quirk that emerges from the quantum mumbo-jumbo of how incoming photons lap against this telescope’s structure and are then gathered up by its hexagonal mirrors. In particular wavelengths.... clouds that would otherwise look diffuse seem to have hard soap-bubble surfaces, skins of interstellar gas that are absorbing ultraviolet light from nearby stars and shining it back into space as infrared radiation. And in the mid-infrared, when space itself looks afire because of glowing molecules called polycyclic aromatic hydrocarbons that are produced by aging stars, colors again get wonky. 'We end up having psychedelic purple clouds'....
Will anything land as hard as the Apollo shots?
Part of the science is the science of our emotions and how to manipulate them with images. We are expected to gape and gasp "wow." Color is big. The word psychedelic keeps coming up. Composition matters. They choose to put solid-looking "vaguely geologic structures" at the bottom to mentally orient us in something that feels like a landscape:
Think 19th-century paintings from surveys of the Western frontier, the photography of Ansel Adams, background scenery in countless Westerns — or El Capitan, from Yosemite National Park, looming in the desktop background of a Mac computer.
They are hoping this will "land as hard as the Apollo shots." I remember how Apollo interfaced with the public. I was a skeptic at the time. I'm quick to feel the manipulation and resist. I'm not saying the science isn't worthy, only that what we are getting is a show about science.

so they admit, that the "photos", are just cgi
i have a friend, that is a landscape photographer, who makes very pretty pictures.
They're based on photographs, then he manipulates them until they look out of this world.
I've told him, that i thought that pictures should look real; and he went on and on about how "nothing is real", the art is all that matters.
I still prefer pictures that look like things.
It's interesting, that NASA also has decided that the art is all that matters.
The Webb picture generator makes very pretty pictures, how much did they cost?
NASA is welfare for engineers.
I'll be more impressed when the NASA images are taken by people in space, rather than by a boondoggle telescope that was billions over budget and a decade late.
Nothing about this is impressive. It's a bunch of incompetent bureaucrats desperately trying to justify their waste of taxpayer money.
TBH, a show about science is about all that will in the least bit register with most people. Even then it's likely to be "Pretty picture(s) that's nice." and they go back to their People magazine, or gossip, or sports, or whatever. Most people have no idea where their food and water come from or where their shit goes, let alone what it takes to provide reliable, steady on-demand voltage (with as many amperes as needed at any given moment) -- at the flip of a switch -- across a wide network of diverse demand.
Apollo could capture the imagination of most people because they were seeing rapid changes for the better in their daily lives. It was but 60 years from Kittyhawk, and most people alive had watched the progress overhead. They marvelled at the new and vastly better roads. Sputnik was a surprising challenge from a new enemy. And so on. Remember, too, that it was less than 12 years from Sputnik to men on the Moon which tapped into the universal human exploration ethos is a very simple way.
Webb is far more important scientifically than Apollo -- and I had the privilege of analysing a couple of small Apollo 12 rocks -- but it is far more esoteric, and therefore of little interest to most people. The scientific aspects of Apollo could have been handled with sample-return and other missions but Apollo wasn't really about science in the first place ... which makes all the difference.
This analysis is way, way, way overstated. Photography is a physical process of transforming light/radiation into another physical or electrical media. In the old days photos were a product of silver and other chemicals. Before color, many photos were hand tinted by artists. Color "Kodachrome" had a specific look that Paul Simon very much didn't want taken away. Fuji and other films have their own look. Each lens has its own personality/bias too, and adding 6 point "star effects" is common in general glamour photos too (but this not a product of hexagonal mirrors).
Digital photos pull energy into sensors, and the technology varies. The sensors collect energy, and there are many editorial/technical decisions to be made. So, it's somewhat arbitrary and somewhat a best guess. But it's nothing new and not really marketing either. They are just trying to produce the best or best looking shots.
Yes, NASA and Biden politicize every single little announcement these days. Biden's polling numbers are really low, so maybe he should be "bipartisan" or something...
The science is brought to you by women. That's always a tell.
As Bart pointed out...
It was less than 50 years from Kittyhawk, to Sputnik ..
it was less than 12 years from Sputnik to men on the Moon..
AND.. It's Been 50 years, since man has been to the moon..
During those 50 years, LOOK at ALL the advancements... Look HARD, pretend they are there.
I DON'T just mean in space.. I mean ANYWHERE!
Sure, computers are smaller/faster, with more extensive comm links.. And THAT'S your BIG CHANGE?
Oh well, at least we don't have to worry about the russians and chinese; like we did in 1972..
Oh WAIT!
’Webb is far more important scientifically than Apollo -- and I had the privilege of analysing a couple of small Apollo 12 rocks -- but it is far more esoteric, and therefore of little interest to most people.

Very cool about the moon rocks! Robotic exploration and sample return missions are the future, in my not so humble opinion - especially weighing cost, risk, and survivability factors. Unfortunately, sample return canisters don’t interview well on television.
Where's the wonder and joy with you people? Last night me and my wild swimming friends did a Super Moonrise swim. The stars were out against a deep blue sky and the water just turning black. A few ribbon wisp clouds glowed above the hillside. The bright yellow orb started peeking through the trees. As it rose, the moon was the perfect backlit frame for single trees along the ridgeline. The moonbeams reflecting off the water comes directly into your eyes, following you every where you go. From under the water, the light is a mass of vibrating corpuscular blobs of fire.
Who doesn't love that feeling of Awe when supercharged by the Universe?
I thought this was going to be about using "vibe" as a verb. Is "vibed" a word?
The universe is a woman. The science wants to undress it a little more - there must be something under the lingerie that is concealed by the last bit of distance; the women want to add cosmetics to what's already been seen.
It's a question of audience. The men or the women.
COSMOS c. 1200, "the universe, the world" (but not popular until 1848, when it was taken as the English equivalent to Humboldt's Kosmos in translations from German), from Latinized form of Greek kosmos "order, good order, orderly arrangement," a word with several main senses rooted in those notions: The verb kosmein meant generally "to dispose, prepare," but especially "to order and arrange (troops for battle), to set (an army) in array;" also "to establish (a government or regime);" "to deck, adorn, equip, dress" (especially of women). Thus kosmos had an important secondary sense of "ornaments of a woman's dress, decoration" (compare kosmokomes "dressing the hair," and cosmetic) as well as "the universe, the world."
Yes, this is a show about science. And a good one at that. However, the Apollo landing was a stoppage-of-time moment for all the people on the earth. It was substance. It was a hard script. Nothing ethereal about it. We shot for, and landed on the moon. "We" being both Americans, and the human race. It was taking what had previously been ethereal, or science fiction, or something that occupied the minds of only those interested in the stars or physics, and made it solid, hard, real- for everyone.
Gazing at images of the universe brings it back to the realm of those interested in science fiction, astronomy, physics, philosophy, etc. It becomes ethereal again. It becomes something different for every person. Or not. Most of the earth is more interested in TikTok than thinking of the vastness of the universe.
Apollo is hard and substantial. The universe is vast and philosophical. Not as many takers of the vast and philosophical. It won't stop the earth as the Apollo landing did. Even though the photographs are amazing and thought provoking. We on earth don't like to think.
if we can have live-cam for snail-crossings why not simply stream Webb-TV
I was 11 when Apollo landed on the moon. Other than being good at math, I can’t think of anything else that motivated me to study Mechanical Engineering. Sputnik, Mercury, Gemini, Apollo.
Science in Gulliver's Travels. The Flying Islanders just care about astronomy and math; for relaxation they have a kind of music that is horrible to everyone else. How to get funding to live this way? They are able to extort money from people below on land. They can get the island to kind of hover in such a way as to block sunlight and rain, and starve people out; they can even pick up rocks in one place in order to drop them in another place. Sound familiar? Gulliver visits at a time when the people below are getting more ingenious about rebelling, and refusing to pay taxes.
Fortunately for the scientists, some of their students, probably not the cleverest, have decided to go down to earth, screw around with crops, and promise that some day the peasants will have more comfortable, and probably longer, lives. (Not much point in achieving one without the other). They seem to have made a great psychological discovery that as long as you keep promising some spectacular hope of a better life, people will support your mad experiments, even to the point of suffering starvation (resulting from the experiments, not from the flying island itself). Collecting taxes to support science will not be a problem as long as you can keep this up. No one in this fictional world has the idea of climbing into a small craft and flying into space; that's too crazy even for the Projectors. The astronomers don't even think of letting the public see through a telescope; this would probably have limited appeal in comparison to three meals a day and a good night's sleep, possibly forever.
Pictures with "psychedelics colors" that "vibe," Man. Who says the 60's are over?
Rhh provides the jealous feelings of the beta toolmaker left back at camp while the scouts explore the unknown.
The website "Astronomy Picture Of The Day" ( https://apod.nasa.gov/apod/ ) has great pictures of near and far space; no need to wait for the Webb output. The archives stretch back many years.
Sputnik was launched in the fall of my first year in school, and Apollo landed on the moon a few weeks after I graduated. Those 12 years generated an interest in science and engineering that spawned the people who created many of the advancements in communications, photography, medicine, meteorology, and other things many people don't equate with space travel research. A lot of folks just joke about Tang.
I had an opportunity to work for NASA at one of the Challenger Space Centers. When the kids take their places in the Space Station Simulator, there's a great deal of excitement, but we didn't always see much enthusiasm in their teachers who were required to come to training sessions before they bring their kids. It's just a "field trip" to them. If NASA is turning information from the Webb into a "science show", part of the reason is recruitment. The generation of NASA engineers and scientists who are working on how to create human living conditions on Mars could be the kids who will find solutions to energy needs here or adaptions to changes in climate. But there's no "hook" anymore.
I just complete Lori Garver’s book “Escaping Gravity”, and it too feel likes so much manipulation and inconsistency as well. Note the title of this post’s article is the “lonely work”, yet we learn there was a committee with a global membership. You get similar things from Garver as a top level bureaucrat who wants to paint herself of a victim of bitter and unfair criticism while simultaneously telling us her stories influencing Presidential candidates to accept her point of view. To the bureaucrat, the President’s vision fails not because it was her bad idea he accepted, but because people refused the follow the bad direction from the President and then blamed her and not the President for the direction. How any of this passive aggressive story telling advances space technology is beyond me to comprehend.
How about just releasing the images and let democracy decide what is best? No sad stories of how hard it is you to decide what the silly masses like. No chest thumping of your participation in global committees that are doing the same work you just claimed to be yours alone. Then we don’t have to hear the retrospective on whether you succeeded in manipulating society as you planned or how society failed you but not being manipulated.
"...quantum mumbo jumbo"
Someone as illiterate as Elizabeth Kessler has no worthwhile opinion to express about the photography from the James Webb Telescope. Some of the commenters here would benefit from a little education in the hard sciences as well.
I suppose most people have encountered the Doppler Effect, either in popular science literature or in daily life, like hearing a fire engine's siren increase in pitch as the engine approaches your position and then decrease as it recedes in the distance. Is that familiar? The Doppler shift affects EM radiation as well as sound detectable by our human ears. In 1929 Edwin Hubble made the most important observational contribution to astronomy since Galileo discovered the moons of Jupiter when he demonstrated that the most light from the most distant astronomical objects is shifted toward the red end of the spectrum, the well-known red-shift. Not only are they red-shifted, but the shift increases with distance, which means that their distances increase at a faster rate the more distant they are. (A few galactic objects are blue-shifted, the nearby Andromeda galaxy or example. Consequently, we know that our Milky Way galaxy and the Andromeda galaxy are destined to collide in the remote future.) This Hubble Ultra-Deep Field image illustrates my point clearly.
Please follow the link and give the image a little study. Many of the galaxies and quasars are blue, while an apparently smaller number is yellow, amber, or bright red. If the most distant objects are red-shifted why the predominance of blueish objects? The reasons are at least two-fold. One, the majority of the blue objects are in the foreground, i.e. relatively nearby and moving toward us. Two, the most distant objects in the field are red-shifted beyond the visible spectrum and therefore invisible. That extreme wavelength shift into and beyond the near-infrared is the entire raison d'etre of the James Webb Telescope. Its primary sensor (the JWT is a digital camera like your iPhone) NIRCam imager operates in the near-infrared wavelength spectrum in order to detect the "stretched out" light from the early universe. This stretched light is invisible to human ears, therefore any NIRCam image rendered for visual study is necessarily artificial, just as electron micrographs of the COVID-19 virus are artificial but nonetheless real. Those of you who snap-snap-snap with their iPhones and Androids ought to realize that every image you take is likewise artificial -- thoroughly processed by the cellphone's software. The unprocessed raw data isn't a picture at all.
Unlike particles and people, the fabric of space-time is unconstrained by General Relativity. Eventually, the speed of recession of the most distant objects will exceed the speed of light, thereby cutting off our ability to study the ancient universe completely, so we ought to take a look while we still can.
The more I thought about some contemptuous remarks about the JWT images and "CGI" the more insensed I have become. Perhaps I should remind everyone that the brain does a shitload of image processing every second your eyes are open. So don't snort and huff about CGI (as if that's what is going on in the JWT, your Motorola Edge+, or your brain because it's not) because you'd be utterly blind without it. You wouldn't know if you had caught a fish or a head cold.
Went outside a couple nights ago to watch the international space station fly over. The weather guy on the news mentioned it would be visible. Couldn’t tell you who was up there or what they are doing or trying to accomplish. Not much in the news about that lately. They do have a website where you can find that info. Not the snazziest website I have seen. Guess people aren’t as interested.
Yet President Biden remained grounded in the old rationale. He said: "These images are going to remind the world that America can do big things."
Some Brit once wrote that you could chart the decline of the UK, by how often Britons used the word "still" in talking about their country. "We are still the world's greatest power." "We still have the world's largest navy." "We still have India." "We are still an empire."
Biden didn't use the word "still" here, but he clings to clichés from the mid-20th century. "This is the United States of America, dammit!" "We can do anything. America can do anything." It's a nice fantasy, but Biden himself can't do anything, dammit!
The images have a theme - Star birth {Carina Nebula), Star life (Stephan's Quintet), star death (Star Death), Galactic birth (Deep Field). And there's going to be pictures of Universe Birth. I love the pictures but I notice that these days the Universe Itself can't be trusted appear on its own without touched-up photos, an ignorant but diverse PR person and canned applause ("These stunning images produced by the JWST" etc.)
Moreover and far worse, Joe Biden is using the photos as photo ops for himself. "In a surprise turn of events, one image was released on its own. [Not quite on its own] It came out the night before and was unveiled by President Joe Biden." Totalitarian politicization strikes again; it's too bad. Because totalitarian politicization has to be followed by retaliation politicization, i.e., "Joe Biden has issues with age and is now showing snapshots from 4.6 billion years ago." "Joe Biden, shown with an image of expanding emptiness inside an aging star." "Joe Biden shows that world is like a Dem politician - gas all the way through right back to the beginning." Etc.
Resisting this, I say that these photos show that the Universe Itself like a child's birthday party with helium balloons attached to chairs, floating on the ceiling and collapsed on the floor while the family sits in a circle in the flickering dark, watching the candles on the cake get blown out. All the meaning of the Universe Itself lies in something in us or nowhere. The rest is gas. And what are we? "When I see the heavens, the work of Your hands, the moon and the stars which You have made, what is man that You are mindful of him or the son of man that You care for him?"
Did any of you see the meme floating around cyberspace yesterday with the photo NASA sent compared to a guy’s granite countertop and the words “Nice try, NASA”? I liked it so much I sent it to my cohort but it never occurred to me there was any hidden truth there.

"Just because you can doesn't mean you should."
Every time I visit what's left of NASA Ames Research Center in Mountain View, I am grateful that my father did not live to see it's decline.
I say #BoycotttheUniverse until they stop looking at it through the lens of a Homophobic Telescope.
When "change" or "progress" relies on massive government spending, it's subject to pushback from taxpayers and lenders. We may have been fortunate that competition with the Russians didn't force us to put a man on Mars by now.
J.M. Keynes thought capitalism was in trouble because you could only build so many railroads from London to Manchester or Birmingham. He didn't understand that you could also build highways, superhighways, and airports. But what do you do when all those are built? What do you do when people begin to object to building new superhighways, or new dams, or faster planes? The romance of new construction and the sensation of newness and transformation passes to other countries. So we progressed where we could, and apparently that is in microelectronics and biotech. There's no guarantee that the US is going to be leading the way in the future in those fields, though.
How can any human not be in awe?
if we can have live-cam for snail-crossings why not simply stream Webb-TV. Exactly.
The answer is because bureaucrat’s want to tell us what we should think about what we see rather than let us see and make up your own mind. The latter has no narrative.
Can't these NASA geniuses figure out a way to show us photos that are real?
What the human eye would see if we were way out in space...no fake color, no points of light on the stars.
Don't tart up the universe like an aging Julia Roberts on the cover of 'Vogue.'
At least Helen Keller doesn't work in that group.
Since the telescope detectors are infrared, if they rendered the images "as is" they would be blank to the human eye.
Actually, I am a bit puzzled by this. This site purports to show the range of three of the instruments as only extending into the red portion of the visible spectrum (and for MIRI, not at all), yet the images shown certainly look like they include visible-light. I understand they can color them any way they want, but is it the case that no visible light (except for red) is collected or is there some visual as well? I would love to find a detailed explanation of exactly the processing that's done. I haven't had the time to look yet. Anybody know of one?
Howard deigns to bestow his wisdom on "you people".
I always quit reading when I see those two words.
Any endeavor that requires public funding (private or governmental) is going to put a lot of effort into the Wow stuff, because most people aren't at all interested in the scientific esoterica of most disciplines. Although in the long run I would argue Apollo was a tremendous waste of money -- no one's been back since the early '70s after all -- in the short term it was a worthwhile effort to Do Something Hard, First.
Like Howard, I'm glad they give us proles something to look at that is simply awe-inspiring. I can't get enough of the Galileo and Cassini probes' images of Jupiter, for example. Closeup pictures of another frickin' planet!!! Same with the Mars rovers.
(Eaglebeak)
Aristotle says in the Metaphysics that Philosophy begins with a sense of wonder--that it is from a sense of wonder that we begin to philosophize, and that we continue to philosophize.
The Greek word is thauma (from which we get thaumaturge--wonder-worker); the Latin word for the verb to wonder is miror (from which we get admire, etc. etc. and of course mirror).
And the Bible tells us that the Heavens declare the Glory of God.

Where's the wonder and joy with you people? Last night me and my wild swimming friends did a Super Moonrise swim.
Poor Howard. Nobody appreciates his thoughts, such as they are. I was in college, majoring in aeronautical engineering, when Sputnik was launched into orbit. There was a lot of discussion about whether the weight was real as it was much greater than that of the US planned satellite, which collapsed on the launch pad shortly after ignition. My wife's father worked at JPL. You were in diapers when I had my wonder and joy.
what we are getting is a show about science
In a word, mediated.
I would love to find a detailed explanation of exactly the processing that's done. I haven't had the time to look yet. Anybody know of one?
they are just using paint, to paint pretty pictures.. Like EVERYTHING our government does..
it is ALL Bullshit

i'm ALREADY in awe, of GOD's universe.. As far as these impressionistic paintings go.. i've seen better
Jeez, I'm actually in agreement with Howard.
I will note that this is a singular post where he isn't being an asshole.
"How can any human not be in awe?"
If you're so lacking in imagination, then your idea of what is objectively awesome is meaningless.
BTW, what is "awe"?
OED: "Originally: a feeling of fear or dread, mixed with profound reverence, typically as inspired by God or the divine. Subsequently: a feeling of reverential respect, mixed with wonder or fear, typically as inspired by a person of great authority, accomplishments, etc., or (from the 18th century) by the power or beauty of the natural world."
"Reverence" is "Deep respect, veneration, or admiration for someone or something, esp. a person or thing regarded as sacred or holy."
What is the object of respect here — the universe itself or the images human beings were able to produce? I think it's the latter.
I strongly support our efforts to explore and understand the universe, including the Webb telescope project.
And heavily processed images of the cosmos are great - as long as they are identified as such.
But they show us colorized cartoons and tell us they are realistic. The Webb "photos" are just the latest example.
Scientists today, particularly government scientists, lie constantly without, it seems, remorse.
It is a great disappointment.
"What is the object of respect here — the universe itself or the images human beings were able to produce? I think it's the latter."
How about both? And it's not to be forgotten that humans are a manifestation of the universe (the old observation that we are the universe contemplating itself)..
"What is the object of respect here — the universe itself or the images human beings were able to produce? I think it's the latter."
Assumptions/assertions outside of a limited frame of reference, with an emotional appeal to inferential visual perception.
My awe is in the universe itself. What awesome God created it? How privileged we are at being able to see it as mere humans.
I recall being a child in the late-60s/early-70s, and there were addresses for Kennedy Space Center and the Johnson Space Center in the back, where I could write to have them send me pictures. When the packages arrived, I was in awe (and I still am) at how powerful they were in focusing my interest in the space program, and astronomy, and the science of rocketry.
They stopped doing this, though. Sad.
What is the object of respect here — the universe itself or the images human beings were able to produce? I think it's the latter.
Very possibly, for the first awesome time, I am with Howard AND Inga. Awesome sauce!
I cannot conceive of the small mindedness coupled with the preening arrogance of a human being who is not in complete amazement...awe... at both what we have learned about the extraordinary scale of the universe itself as well as the achievement of mankind to help us get a glimpse of it. Quaestor has given us an excellent review of the science.
My daughter is an astrophysicist whose particular specialty is spectrographic analysis of deeply red-shifted galaxies from which she reports significant science. When I read her papers, I see plotted data images that reveal about as much information to me as I can obtain from looking at an gall bladder ultrasound image or a dental x-ray. This falls into the category of don't-try-it-at-home. It's best to leave it to the other 9,999 people in the world who also have a PhD in astrophysics.
And yet now, even the least of us can view 20 megapixel deep field images of a tiny speck of the heavens on their Obama phones and can learn a little about the extraordinary privilege it is to be consciously alive and to be an American.

Last night, the local PBS station broadcast a carefully coordinated Nova episode on the James Webb space Telescope. It had the latest pictures so it was, in essence, still hot from editing when it hit the airwaves. I liked the show overall, though they could have cut out the James Webb controversy nonsense. It carried through the whole development process from concept to unfolding in space but the payoff was the pictures. The most dramatic, to me, being the comparisons between what Hubble can see and what JWST can see. Wow!
It's all false color because we can't see in the wavelengths JWST is observing. I assume there is a standard for this, something like a linear shift from infrared (IR) wavelengths to visible (VIS) wavelengths.
The meaning of it all? That's the rub. I don't feel any smaller but then being a science fiction fan I've had a bigger picture of the universe for a long time.
We put men on the moon a half a century ago, and what has NASA done since, with the now hundreds of $billions$ they were given? NASA became a large bureaucracy, and, as a result, did very little over that time of any real merit, in terms of getting to and staying in space. It got so bad, that they were paying the Russians to bring our astronauts up and back from the ISS using their rockets. Instead, NASA was, for example, working on Muslim outreach.
NASA no longer needs the Russians to perform their minimal job, in the eyes of many, if not most, Americans. Instead, they can now hire US based space companies to do the job, whether it be bringing people and supplies to the ISS, or throwing satellites into space, etc, far cheaper than the Russians can or they can themselves. All it took was a bit of competition, some good engineering and innovation. We are now talking again about returning to the moon, visiting Mars, and mining asteroids. Stuff that I grew up dreaming about in the 1950s and 1960s, but became dying dreams, as long as NASA was the only game in town.

That's the source of real awe. Anything government touches since WWII has turned to shit. The Apollo program was the single exception.
How is the photo processing done? Here's part of the answer.
https://webbtelescope.org/contents/media/images/2022/035/01G7HRYVGM1TKW556NVJ1BHPDZ
Still - what color in the visible spectrum is a spectral line in the non-visible spectrum? Like the noise of a tree falling in a forest where no one can hear it?
heavily processed images of the cosmos are great - as long as they are identified as such.
I agree with this - it's important to know what you're looking at, in order to calibrate your response if for no other reason. For instance, my daughter and I recently got professional makeup done for a wedding (with the wedding party). We looked fantastic, but utterly unlike our everyday selves. So it's not very meaningful to us for people who see the pictures to say "You both look so [complimentary adjective of choice]" without everybody's understanding that we'll never look like that again... My daughter is in fact beautiful, but she doesn't look like that on the daily and doesn't want to do that much work!
As for the images under discussion now! I appreciate these efforts to enable us "visible spectrum" users to have some way of experiencing the rest of the spectrum - like the images of flowers "as seen by" butterflies and moths, for instance (it's not actually "as seen by," only our best way of representing the way they see within the limits of our piece of the spectrum). But I was gathered with friends last night and some were talking about how these Webb images are "how it really looks," which frustrates me a little.
OK, I admit it, it was a book club meeting. Another woman exclaimed at one point, "Did you know that women actually don't have equal rights?!" followed by a whole thing about the ERA. The muscles around my eyes are still tired from my straining not to roll them.
“ Stars in Webb images have six points, unlike the four spikes common in most space photography, a quirk that emerges from the quantum mumbo-jumbo of how incoming photons lap against this telescope’s structure and are then gathered up by its hexagonal mirrors.”
Nothing to do with “quantum mumbo-jumbo”. It’s simple diffraction of light waves from the edges of the hexagonal mirrors, an effect Huygens would have predicted three centuries before the invention of quantum theory. It’s the NYT’s science reporting that’s full of mumbo-jumbo, as usual.
I was born in 1943. I grew up reading Heinlein's novels and looking at Bonstell's paintings. I was convinced that in my lifetime I would be able to travel to the Moon (at least!) and more than likely to Mars. (I didn't know if I WOULD go to those places, but that I COULD). I remember watching Sputnik fly overhead, and later US satellites. I remember the earliest US manned suborbital and then orbital missions. In 1969 I watched the first moon landing -- and that's when I realized there was something wrong. I was in Army Basic Training at Ft. Bliss TX and the word came down from ABOVE that all trainees were to be released and allowed to use the "Day Room" TV to see the broadcast of the landing (the barracks included this recreational space, but these facilities were normally off limits to trainees). I watched every minute. But of the 200 trainees in the company, there weren't more than a dozen of us who watched the landing. The rest of the guys were shooting pool, playing cards, etc. To me that was the end of the Space Age.
Yes I think the Webb telescope is great, but to me it's science, not adventure.

Anything government touches since WWII has turned to shit. The Apollo program was the single exception.
I'm not going to argue with Dr K, but.. The Minuteman Program turned out pretty good.
I recently read Minuteman: A Technical History of the Missile That Defined American Nuclear Warfare, by David Stumpft.
He makes a Pretty compelling case, that Most of what we consider "invented" by and for Apollo (specifically, integrated circuits and computers), were Actually made for Minuteman.
Who was the biggest consumer of IC chips during the '60's? You guessed it; Minuteman.
The LGM-30A Minuteman-I was first test-fired on 1 February 1961.
By July 1963 a total of 150 Minuteman I missiles were placed on operational alert, by October 1963 that number increased to 300 missiles, 450 missiles were deployed by March 1964 and in June 1965 F.E. Warren Air Force Base in Wyoming, placed the 800th Minuteman I missile on operational alert. Cost of each Minuteman I missile was $1,315,000.
(The launch facilities (silos, wiring, land. etc) actually cost more than the missiles.)
Less than Two and a half years, from first test firing to 150 operational missiles. Missiles with warheads, in silos, with crews.
Of course as the book pointed out; There would have been no Minuteman without Polaris.
Thanx Navy!
