small correction / addition: most cameras don't work with 3 separate sensor, but instead use a "bayer filter". which is a mask for each pixel, most commonly 50% of all pixels are green, 25% are red and 25% are blue. which creates a lot of missing data, which is interpolated from neighbor pixels. which makes the image quality and especially measurement capability of color cameras a lot worse than monochrome cameras. this is the main reason in all science and industrial application you use monochrome cameras wherever you can, and try to use or choose the lightning source and or filter as best as you can.

@Lucius_Chiaraviglio

4 ай бұрын

As someone who has worked with cameras for scientific applications -- specifically microbiology research, I was going to say essentially the same thing. Some high-end cameras do exist that have beam splitters directing light to 3 (or more) separate sensors as shown in the diagram in the video, but those tend to cost lots of money as well as take up more space (especially important when portability is at a premium), and hence are not found in most consumer products (also, it's a good guess that the beam splitter will just outright lose a significant amount of light). If you tried to take a picture of fluorescently-stained cells with bacteria-sized and even smaller features with a consumer-grade camera, the lateral separation between red, green, and blue (and in a few cases cyan) pixels on the CCD actually matters, and could cause you to miss features of a certain color that just happened to fall on the wrong color of pixel. Plus, spectral bleed between different fluorescent dyes means that you really need to photograph with 1 color of excitation light at a time anyway rather than trying to do all at once. So we also use black-and-white cameras with filters.

You _almost_ said it but I wish it had been clearer: There’s nothing particularly “true” about how the human eye happens to see color. And “what it would look like to you if you were nearby to see it” is severely counterfactual. It’s not like you’re going to pop around the corner and, “oh look it’s Neptune!” Also human perception depends heavily on lighting conditions and context and sunlight is quite a bit dimmer out there! So, there’s nothing (as you said) really wrong with the old images. And, to my mind, there’s nothing particularly “more right” about the new ones. As for the filters deployed with the camera, they fortuitously overlap with the human visual range, but I presume they were chosen for detecting specific chemicals and reactions in the atmosphere. Processing that data into “true color” is neat and good for public outreach but not of any scientific interest. Indeed, the older picture is more useful since it highlights interesting atmospheric phenomenon. Most of this is in your video! I just hoped to see the idea of “true color” deconstructed a bit more.

The thing is, in some sense I woild argue the false-colour image better represents what the human eye would see. Because the human eye would have better resolution than the camera they sent on Voyager. So it would be able to pick out the details you would miss if you look at the true-colour image.

I watched a video for amateur astronomers about how to take a picture of Andromeda. The most interesting take-away for me was how much effort it took. The guy took thousands of photos each with a full second of exposure time and then had to use software to sum the photos together to make a single photo. Doing this actually improved image quality, because a single photo has noise, but if you have 3,000 photos you can use math to determine what is noise and what is "real". Even then, he had to manipulate the photo for hours, endlessly manipulating colour gradients until something which looks like we expect Andromeda to like appeared. It was an eye opening video. Much of my passion for science and outer space is fueled by the amazing images we get from professional astronomers (as well as the "fake" illustrations that are often found in popular science books--but still cool). I am glad you talked openly about image manipulation. I've come across other astronomy KZread channels that denied that images require manipulation.

Although not a member of the press, I was physically present at JPL for both the Uranus & Neptune flybys, and still have my "press kits" from the NASA Public Relations Office for both events. Many color photographs are included, with explanations printed on the back of each. After a quick glance through them, I see at least one which gives an explanation...for example: "This color composite was made from the clear and green filters of Voyager 2's narrow angle camera." (And yes, I'm mortified that you weren't even *born* then). 😮😂

Fascinating. Optically looking at Neptune through a telescope (with a trained eye) and comparing it to other objects, it definitely looks bluer. Uranus always looked somewhat more paler and sometimes greener (cerulean?). It's very hard to explain to explain to the public why objects through optical telescopes don't have the color that pictures do. Even amateur astrophotographers, use false color or "enhanced" color for their pics. I've also had long discussions with astrophotographers about why the the colors are different in their printed pictures compared to their RGB color monitors.

I'm an amateur astronomer. Neptune is a deep enough blue to notice at the eyepiece. Uranus is so white the bluish tinge is hardly noticeable. They are both in the night sky these days...have a look for yourself!

The problem I have with "this is a true-colour image" is that it raises the question "under what illumination conditions."

As a young science fiction space geek I remember watching the voyagers get launched on the "grand tour." And the Viking landers and mars - the mid 70's were a big time for planetary exploration ( and Star Wars of course ;) ) It was always made very clear when colours were enhanced or altered as after all this waas the first time anyone was seeing these things. Pictures from space were still new. Indeed, I had wondered in the last 20 years why photos and diagrams increasingly showed Neptune as this brilliant blue colour. I don't think everyone forgot that Neptune didn't look like that. Unless "everyone" means people under 35-40. It kind of shows how real and powerful generational turn over is.

In 1989, I was in college for aerospace engineering, so very tuned in to all the NASA probes and the imagery being sent back. I remember VERY well that they were false color images, and I never forgot that Neptune was shown in false color. I never assumed the deep blue was correct. I don't know who "forgot" but at least it wasn't me! By the way, it was in college about 1988 that I got my first e-mail address so I could send some undergrad research results to my advisor, who was also sometimes working with NASA Langley, so sorta "internet".

Most people don’t know Uranus (or its Roman equivalent Caelus) was the god of the sky. Most people *DO* know Neptune was the god of the sea. (How many works of fiction have called a ship “Neptune”? How many cities on coastlines are named “Neptune”, etc.) Neptune = sea = blue. Uranus = planet = …god of some kind? From some mythology?

Whenever this kind of story comes up about astrophysics images I always think it’s a great time to point out that the concept of colour as we humans see things is almost entirely arbitrary. I do understand emotionally feeling a little upset that you wouldn’t be able to see X or Y with your own eyes but it’s always neat to remind ourselves that we can’t see the vast majority of the EM spectrum and it’s kind of arbitrary (well not evolutionarily) what parts we can see.

The moon is the color of coal. That factoid astounded me. We think of it as this bright white thing in the sky - but it’s remarkably dim. The moon is less reflective than any planet in the solar system. And orders of magnitude less reflective than the most-reflective moons of some of the outer planets. If it were to suddenly swap places with Enceladus, a moon of Saturn, even though Enceladus is only 1/4 the diameter, it would be far brighter in the sky.

@@AnonymousFreakYT I've heard it's basically dark asphalt.

I reme.ber 1989, Dr. Becky. You didn't miss that much. I remember the photos, and I vaguely remember that Neptune's photo was doctored to be more blue. May have been mentioned in National Geographic magazine. I must admit I forgot in the ensuing decades.

I feel old. I like hard cover papers. And I remember having the same conversation with technical journals (geology) about them changing the author more for colour pictures and diagrams. Thank you, Dr. Smethhurst for the great information and reminding me how far we have come in presenting information

Noooooooooooo 😢😢😢 Now it looks so... average and bland.

It just looks like Uranus now!! Look how they massacred my boy!!!!!

The beautiful dark blue colour of Neptune can’t be artificial, that’s impossible! *Searching my feelings and then knowing it to be true* NOOOoooooo!

I wish I had a teacher like you in school. You make it all make so much sense! I have always loved this subject but would get frustrated because I didn’t understand everything and my teachers were so dry thanks 90’s

This was really fascinating. I really like when something I "know" turns out to be different than I thought like this. Also the mention of pre-internet life absolutely boggles the mind, it wasn't even long before I was born but I can't imagine it. Crazy.

I remember the statements about false colors. I watched those pressers as they happened. Hard to believe you weren't yet born in 1989. So much history you have missed :) Keep up the great work Doc!

I think one of the reasons they made the darker blue one the common one, is so we can distinguish between not just the features, but distinguish it from Caelus

Great video, Dr. B...👍

Really liked the cut-in clips from movies/tv in this video - they fit in perfectly!

I remember reading about the flyby of Neptune in 'Odyssey' magazine when I was eight years old. Learning that you were not yet born at that time has instantly turned my hair white and ruined my knees.

Becky I asked for and received your black holes book for xmas. I can't wait to read it

Woaw. I've been wondering why Neptune was soooo much bluer than Uranus for a while too

As a person from outside the UK, I watched the "Should we Neptune..." bit a handful of times before I going to the bloopers were right after. I LOVE that the Northern accent came out and I vote we get a Night Sky News episode in full laid-back, natural accent. Makes me think of how my "southern/country" accent comes out after a couple of drink, hahaha!

In the runup to JWST I kept thinking it’d be super if astronomers would put some kind of notation on images to indicate what the processing was. Probably the ID space is to big. And the press would likely just crop it out anyway. Also I’d super like to know how I know Uranus and Neptune are the “same” color and that blue image is contrast enhanced. A small victory for someone that was sure you could see stars in the daytime from the bottom of a well until well into adulthood.

"I wasn't bon in 1989" I turn into a pile of dust.

Back when CD ROM was first around, NASA released all the raw images on disc... I wonder if I've still got my copies kicking around somwhere...

Thanks for the information

Im not finished but your book is amazing. thank you for taking the time to get it to all of us.

HaHa, Got me Dr, Becky. That intro to your ad was sooo smooth I watch it all the way to see where the blue bar went. 😋 By the way, You got the blue bar colour to dark, It should be Surrilium.🙄

Very insightful information. 👍

Speaking of the VTL, I visited the NSF Cerro Tololo Observatory AND the ESO Paranal Observatory ( where the 4 8.2 meter scope of the VTL are) back in november 2023. Very impressive. I also drove as close as I could to the EELT construction site and took pictures of the structure! Both were impressive visit.

You’re terrific Dr. Becky. Thank you for giving us great information. Are you finding out that the JWST is rewriting cosmology? Take care.

Hey Dr! Love your content! Can you please do a video on inflation (why do we need it in our theory) and the observable universe vs the entire universe? Is the entire universe infinite? ❤

1:05 haha, is that your meme? A Devil-Neputune-Meme! I love it!

10:04 your academic rage is showing 😂 I love it and fingers crossed that you get to use it soon!

I always felt that Neptune's images were a bit too bright ever since founding out that it was a gas giant. It often breaks my mind that gasses in shades of blue would be that vivid in space, when they're more close to white with every example here on Earth. I'm really happy to see that it was just a publishing issue rather than a major error with either NASA's or Voyager's instruments. This also gives me confidence about me constantly forgetting about schoolwork and projects. If PhD astronomers with federal backing can make a mistake this large, then I too can be a whatcha-ma-call-it

Thanks for that Alias clip!

You bring up a good point about Uranus: It was near southern solstice when Voyager 2 visited it though it is close to northern solstice now. It is possible that it might not be as bland-looking in its equinox phases.

First, I remembered the press conference where it was clearly stated that the image displayed was in "false" color. Second, was the thought that...boy, am I old.

Strange, I remember that they look alike since a long time. I think I saw this on some exoplanet paper talking about ice giants, mentioning that as a side note and showing the true color pictures of both planet.

You truly made me smile today from watching this. 😊

I was a teen in the late 80's, and I remember that Uranus and Neptune looked very similar in initial images that were released. I think the explanation was that they had similar atmospherical composition. It was a surprise to me years later when I saw other images and Neptune was so much darker. I kept thinking, "weren't they very similar in color?"

I remember all the magazines I read almost always read "false color image" and then some would go on to explain why they were false color. They went on about this a lot with the Viking landers.

I remember being home from school sick and watching the Neptune images come in live on TV with my Mom.

You don’t know how much I loved the “The Devil Wears Prada” reference

I'm glad to see Mastodon and the fedisphere getting some attention and citations ❤

Interesting that some spectral type M stars like Proxima Centauri don't appear red to our eyes but others like Betelgeuse do.

Its to do with brightness and size a red dwarf even one as close as Proxima Centauri is tiny and thus isn't very bright and appears as a single pixel dot Betelgeuse on the other hand is absolutely enormous and very luminous with a size great enough that even at something like 500+ Ly we can still resolve its light into a disk with powerful telescopes which we can't do with the faint Proxima Centauri. The thresholds of these objects happen to be in the rage where Betelgeuse is bright enough to trigger color vision in our eyes while Proxima Centauri is to faint to do the same.
