Is the colour in space images "real"?

Are you fascinated by beautiful pictures of objects in space but always left wondering whether the colour shown is “real"? This video is all about how astronomers use colour in images to best highlight the physics that is going on in each object. From how cameras work, to colour theory, to images in space, we’re covering it all in this one.

So finally... someone clearly explains how these photos are processed and created. When I first saw the Eagle Nebula photos from Hubble I was astounded at the beauty. Then, regrettably, I was informed the color was fake (no Santa Claus) You can imagine the let down. However, I still was mesmerized by the glory of the photo. Now, some years later, Dr. Becky lifts my spirits....Santa Claus is real....in a way. That's good enough for me. Thank You Dr. Becky.

Do the Nebula forms change? How 'long' do they hold their forms? Also is there correlation of 3's in physics, like RGB images LWH? I cant understand 'black' under RGB, but are there primary 3's in sound, fluid dynamics or gases? I know sound is technically light, but sound in its physical shape needs density or pressure or even suction as -db? (light killers?) Looking for items which correlate to 3dimension primary or 2d differences. Sorry to hijack your post, off topic, however I did get some 'crescent' moon photos under a campfire during this moon Venus phase. Are the frequency of occurring toenail Moons unusual? And now we will all be more prepared for that robot feed'n contest. I'm trying to show the future, not anticipate it. We've walked toward the sunrise, not quite at sunrise (- hurry ?) And away from the sunset, making camp before the sunset As long as the Eldest remember, and as quick as everyone could go, altogether with what we can carry. (discuss?) We've always kept going; over little waters and around larger ones. But all the arounds now: Just go into more water, and the mules are moving against the sunset and the sunrise. And someone needs to tell the Elders that the gods must have drowned -

I wish she had made more out of the whole RAW data thing as thats really how any non-phone camera works. You essentially tell the camera (espically if it has any kind of computer in it like LSDR's do) what data you want it to record and it captures the light and colour baised on the settings you have applied. The best images come from RAW files since then you can edit them more without having to worry about lost data compared to say a JPEG which is a compressed loosy (cant remember spelling) file where data has been essentially deleted for the the sake of reducing file size to help with managing storage. I also feel like it isnt really accurate to say a camera takes photos in black and white as even she herself explained that they capture both BW and RGB data at time of capture and while you can tell the camera to only keep the WB data it isnt taking it in WB specificly... In fact a RAW file you get when using an LSDR has a very large amount of data that can be used to edit and adjust the colour and light values in the image.

When someone asks if the color is "real" they normally mean that, "if I was there, could I see that with my eyes"? For most astronomy photos, the answer is simply "no". That doesn't make them less beautiful photos though. In fact I would argue the ability to see things our eyes can't normally see is even more beautiful.

@textbooksmathematicstutorials 4 жыл бұрын

The only thing that exist is frequency and wavelength in the electromagnetic spectrum. As long as the camera detect the wavelength and the frequency of the photon that's all it take to codify it in green, blue and red and adjust their intensity to project the color on the photo that the frequency and the wavelength of the photon represent. This is because color do not exist. Color exist only in human consciousness (the hard problem). In the photoelectric effect, light incident on the surface of a metal causes electrons to be ejected. The number of emitted electrons and their kinetic energy can be measured as a function of the intensity and frequency of the light. Is this that allow the camera to know the frequency of the photon. That's all the camera need to know the frequency of the photon so it can adjust the red, green and blue light accordingly so the color a photon of such frequency create in human consciousness through the brain can be produce.

@BrantAxt 4 жыл бұрын

@@textbooksmathematicstutorials I know that all frequencies are real in the sense that they exist. I'm just pointing out that when most people ask the question "is the color real" they aren't asking "do those frequencies shown in the image actually exist", they are normally asking if their human eyes could see that same image through a large enough glass telescope. When we capture one frequency of the spectrum and then display it as a different frequency that our eyes can handle, MOST people would say "that's not real color".

@markmuir7338 4 жыл бұрын

Great video with clear explanations! One nitpick for technical accuracy: CCDs and CMOS both read-out one pixel at a time. The difference is CMOS sensors have an analog to digital converter integrated into each pixel (because they can). CCDs can’t do this because they are made on a different substrate and use voltages incompatible with digital electronics - they have to share a single A2D converter on a separate chip. This makes for a slow read-out, and introduces extra noise. But the CCD itself is so much more sensitive to light than silicon, it more than makes up for that difference in noise. Having all pixels go through the same A2D converter also has the benefit that they are more consistent (the noise created by each A2D converter will be subtly different - making each pixel in a CMOS sensor produce slightly different results for the same signal). Hope that helps anyone who’s interested.

This is so great, I was just wondering about this. And learned more about cameras/telescopes along the way! I know some fields use fancy Bayesian statistical methods to try to de-noisify pictures for image processing - do astronomers use those or would they risk obscuring unexpected subtleties?

A great explanation of how the images a built up, and you have taught me something about my digital camera. Thank you.

For someone who was thinking about taking up amateur astrophotography, this episode has provided a valuable and informative insight into how these images are put together. Great explanation.

@@DrBecky Hi, correct me if I'm wrong, but what I have understood from your video is that, if we were in front of a nebula, for example, we either would see grey, red or nothing (considering it's gas, and we rarely see gas except in smoke grey colour) ?

I just want to give a little shout out (a Thank you) to your inclusion of the "out takes". This is the part of the video that I actually look forward to before clicking the "play" button. I really enjoy your sense of humor. I am already looking forward to the next collection of "out takes". PS: I also enjoy how you present the science. I became interested in astronomy while in the 6th grade (1963) and have been following it ever since. Keep up the good work.

That was an excellent description about a complex concept using easy to understand terms. I have been a photographer for years and understand types of sensors, filters, and objects being photographed. I learned a lot - thank you. I am continually amazed at images taken of distant interstellar objects. If some of the early pioneers in astronomy could spend 1 night with a giant telescope, they wouldn't believe their eyes.

I feel so smart for understanding the photoelectric effect and how emission and absorbtion works hahahah. It feels great to watch something and understand it after you learned it in school! I look forward to learning a bit about astrophysics this fall when my physics course continues. Currently (or at least just before summer break) we worked with fields, revising what we did in the first course on gravitation etc. I really look forward to learning more, you are so inspiring!!! :D
