The nebulae are very colorful right out the camera with no filters. All it takes is long exposures. The clean the noise from the long exposures, we take a lot of them and stack them. The images are beautifully colorful!
I've searched trough some ionised gas emission data , and Aperently Oxygen glows GREEN and Not blue , with hydrogen switching to blue at that energy level . . so in a way , we do have rgb color pallete for nebule , . just there's so much hydrogen that it washes out any greens yellows and oranges
I used to have a Celestron C-8 telescope, and by far the most colorful object I ever observed was the Orion Nebula. Just astounding reds, blues, purples. Far more colorful than anything I observed in our solar system (everything but the Moon required long photo exposures to get full colors and detail). Goes to just how much energy and scale nebula have. I was awestruck. I 'think' you can even see it with ok binoculars on a clear, dark night away from city lights.
yep it is worth noting that our solar system is currently inside what to distant observers would be a Nebula from a 2.6 Myr old supernovae remnant but we would never notice without telescopes as the "nebula" emits in the kev (kilo electron volt) range of the spectrum i.e. in soft X-ray light
Earthly scale`? Well then that is wrong as well... ... since the typical nebula is immensely larger than Earth (or our Solar system for that matter) Edit: "is", not "are" (or nebulae and not nebula)
@Fireball XL5 Yeah, the video should have said a cubic centimeter of *air* at sea level on Earth, as opposed to just saying a cubic centimeter at sea level on Earth. Most assuredly could give the wrong idea across. Personally, I found that comparison to be more confusing than helpful. I was hoping he would compare a cubic centimeter of cloud matter ( Obviously a rough estimate, as the particle count varies greatly in clouds.) That would have made a lot more sense, since he had already compared the 2 just seconds prior to the chosen comparison.
@@kari7403 Your conclusions are false: 1. clouds are merely medium density air with high water vapor content 2. That they float in the lower atmosphere means they are almost as dense as sea level air (relatively speaking) So if air at sea level has 1x10^19 particles/cm3 then Clouds have 0.5x10^19particles/cm3.... hardly a more human number so to speak.

A nebula the size of the earth and it could weigh around 3kg that's totally insane ? shows how diffuse they can be. Astrum mind blown thx never stop........
I recall visiting the McDonald Observatory in West Texas where there were some large commercial telescopes (maybe around 12" mirrors) available to look through to see nebulas in the night sky. They pretty much were black and white and shades of gray. To be honest, I was a little underwhelmed and disappointed.
Awesome video. Loved it. Just one thing, I was wondering why birds chirping were added to the background music around 0:36. Space birds flying threw the nebulaes? *Nothing can quite compare with simply looking up at all the shimmering stars studding the vast dark blanket of space, all through the glass roof of my spaceship, while listening to the birds twit n sing.*
The radiant energies are look like' to the capacity to read or record them. The EM field is within or beneath appearances - as a cellular and filamentary 'self-structuring' flux that has a non local substratum to whatever local expressions - that include EM radiations - and neurons and biological cellular matrix. We are brought up to think life is inside us - but is it through us as a unique expression of an Infinite?
One question that has worried me for years is about the transparency of gases. Helium and hydrogen are transparent so how come the images of star-forming regions of nebulae look so "thick" and dark? Are those gases opaque when hot or compressed? Are there huge transparent gas clouds somewhere, and how could be detected?
Thank you for explaining so clearly. The comparisons you make help me a lot. E.g., that one showing a nebula the size of earth and then mentioning it only would weigh a few kilograms. Wow!
How many times did the enterprise take refuge in a “dense nebula” to escape an alien enemy. Sorry captain, there are no dense nebulae in space, we’re sitting ducks
I remember when I first saw an image of the Horse Head nebula. Even now, all these years later, it's still difficult to take on board just how massive they are. Thanks for your insight. Amazing!
You might have mentioned. Hubble pictures start out as shades of black and white. Individual images from Hubble's cameras retain no color information as such, other than the color of a filter, which selects a range of wavelengths from the full spectrum of light. A black and white (monochrome) image most realistically represents the range of brightness in such a single image. Just a little clarification.
Okay say yeah the colors aren’t real, but what a simple yet efficient af way to know what the particles are and in what concentration. That means if an RGB splits as separate overlays, the white would be a visual concentration of everything in high volume, but in a flatted 2d perspective because of the heat mapping. Sick🤘🏽
The thing you always see in sci-fi are these solar systems and planets bathed in the light of a huge nebula. I always wondered how much artistic license the production team were adding to the look of these places. What would our world look like if it was right next to the horse head nebula for example?
There are search engines which search backwards. You should try it. Then you will see who uploaded this picture, sorted for size or whatever you choose. And then you can look who let's you download it. NASA allows, if it is their content. ESO too, if I remember right. Look for backwards picture seach engines. I am sorry in the moment not to remember any name. But they work excellent. Good luck!
what a great video explaining nebula.. i always find the pictures we see confusing and i can't understand them, but this is really helpful.. thankyou 🙂 x
what something 'looks like' depends on the eyes you possess, how sensitive and what wavelengths they detect. So, one could say that IS what they look like, but not how our eyes would naturally perceive them.
This is why this is my favorite channel on RUclips. I knew the images were composites but I never stopped to question the meaning of the colors. Great video.
I always knew that the matter in nebulae was sparse, but never realized just how sparse! Guess even the world's smartest man (me!) can learn something new!
Question for all you smart people , if nebula are where stars are born and the nebula's particles are insanely diffuse then how can such a weak force as gravity pull these particles together to form a star ? Sincere question.
So, if I got into a starship and flew out to these nebulae and parked 10 ly or 5 ly away, or even inside, and looked out a window I would see... what? Colored clouds? Or would I be too close to see them at all?
With your natural eyes? Most nebula would appear as a faint glow. The only reason they are so bright in photos is because of the long exposure time. However nebula like the Tarantula Nebula... That would be really bright!
I like looking for images inside of clouds. At 3:13 on the left, I see a dog with two small black eyes, a big round nose and his mouth just below his nose.
Nebulae have colors, the problem is that the only way you can see the colors with any clarity or brightness is with the intervention of technology (long exposure photography and post-processing). If you were to go out into the Universe with nothing but a spacesuit and your own two eyes, you would never be able to see all of those sights and colors. Our eyes see such a limited part of the light spectrum and they aren’t very well adapted to dark environments. And the distances in the Universe make it impossible to ever get close enough to see any of these structures in such impenetrable darkness. So the Universe to the human eye is unfortunately way too big, way too dark, and not so beautiful.
These gases are ionised plasma that makes up about 99% of the physical matter in the Universe. The electrical force is about a billion, billion, billion, billion times greater in magnitude than gravity - and the volumes of what we call 'space' are likewise vaster than our general human comprehension. The contributions of plasma physics to a new understanding of the Universe are to a significant extent blocked or pushed out by gravity models. However, those who align in the new perspective do not have to make lots of dark fudge and very silly conjectures as to why nothing is as the model predicted.
Nebulae are extremely faint in reality. Orion constellation, for example, is covered in one huge nebula. But you can't see any of it with the naked eye.
I take my dog for a walk. And if it's late at night I will stand and stare at the night sky. And my breath is taken away every time. Unless of course it is cloudy lol Love your videos.
I am gonna get my first telescope soon, and i can't wait to see these beauties, of course i know that with the naked eye you see way less, but i just want to see even a few of their photons
If you want to be amazed, planetary nebulae are one of the best targets. Ring nebula for example look exactly same as the pictures on the internet, except colorless.
I bought a Nexstar 6SE today, partly inspired by these wonderful videos. I'll let you know how it goes, they can be had for £500 on ebay but apparently have the capability to image some wonderful objects! For half the price of an iphone you can see the next galaxy :D

Redshift is not noticeable. Hydrogen emission dominates about 10 to 100 times more than any other light. Most pictures need the red light toning down to make a nice image.
I'm curious, are these the emission bands that we see in the lab, or are they corrected for the "stretching" of the wavelengths due to overall expansion of the universe? If the latter, then are each nebulae corrected for their specific distances from Earth??
Red shift is pretty insignificant on these short distances, it only starts really mattering with distant galaxies and you aren't going to see any nebulae that far away.
HELP! At 6:28 there are some unusually shaped objects in the top left-hand corner of the picture-there is a slight hole in the middle and then a ring around that and then another see-through ring around that before a final ring around that again- does anyone know what these are? Thanks!
No their not that colorful hubble uses light filters to see the colors and the colors are actually the light reflecting off of the chemicals/molicules in the nebula and each one reflects a different color if you were to look at it up close without a filter all you would see is a large cloud of dust
The nebulae are very colorful right out the camera with no filters. All it takes is long exposures. The clean the noise from the long exposures, we take a lot of them and stack them. The images are beautifully colorful!

Another great video. It always bugs me how nebulae are portrayed in movies and TV, as if they're like dense clouds on an Earthly scale.
Some parts are like that, precisely where a solar system is forming. In the Wrath of Khan the Mutaris Nebula is apparently a star forming region.
