Which makes me wonder.. at the beginning she said all the stars look white at a distance, is it because we couldn't tell what "color wave" they were and that maybe the ones that ARE green would look it if we could get a closer look with out damaging our eyes from the mix of BRIGHT colors?
Wait, so.. technically the white stars ARE green stars? I get what she's saying (albeit it was still confusing) but I just realized that she practically said we see the green "colored" stars as white because they're balanced in the colors heat wavelength?
A star that peaks *anywhere* in the visible spectrum will look white to us. For a star to have a noticeable tint, it's got to be peaking way down in the infrared or way up in the ultraviolet, or the difference in the visible wavelengths just isn't enough for us to perceive. So not all stars that look white are scientifically "green." Some are "yellow" or "red" or "blue." It's really just about semantics and scientific precision vs. human perception.
Yes, the primary colors of light are red, green, and blue. The primary colors of pigment are magenta, yellow, and cyan (which many art teachers incorrectly call "red, yellow, and blue").
Again, you're thinking about pigment, not light. Remember that when you're looking at pigment, the color you see is the color that the pigment reflects. It absorbs everything else. So when you add two pigment, you *reduce* the number of colors being reflected. With light, the color you see is the wavelength of the light. So when you add two colors of light you *add* more color to the mix. The terms "additive" and "subtractive" mixing come from that.
It didnt say anything about primary colors, if you have an old tv, look closly at it when it is turned on, and you will see little boxes of red, green, and blue
What is the largest star known name and color? Are larger stars considered more unstable than smaller ones? Is it possible a star could be as large as the circumference of our solar system? Is it known if two stars that weren't binary or trinary system ever collided?
Look it up. I did. It streches the orbit of saturn. A star bigger then our solar system would be so unstable and so heavy that it would implode onto itself.
A star as big as the planetary solar system would theoretically swallow its own light. In real life, stars never form that big (not even supergiants).
Well, as with most things, it depends on your definitions, whether you're talking about color perception or the scientific measurement of the wavelength of the light...
I couldnt be a pro astronomer. I'd never sleep and live under the main refractor. grow a beard and keep a cat nammed Pistol star. thx for the clearing up of that color shift i see. wonder if i can get it on camera.
so if a star is moving away or towards us does that manipulate the black body curve? I've noticed some stars actually shudder with different colors. I know a large part of it is just our atmosphere but it's still cool to see flashing different colored stars. like looking at a flourecent bulb through a fan. it'll change colors.
This is the type of video that should be on you tube,...plain ,simple perfect for teaching our kids about the world we live in. hmm not the other ..rubbish..
If you look into sun you can see that it has many other colors. Like she mentioned green, and just a little of the purple color, but it's moving, so the colors switch all the time. Yellow, green, purple, blue and so on, all mixed together, because of the fusion in the sun, which turns hydrogen into helium.
Cool. Thank you for the explanation. I use to tell my first wife that if you looked hard enough, you could see the green part of the spectrum while looking at the setting sun.
Those are the primaries for *pigment* (actually, it's cyan, magenta, and yellow, but for years art teachers have been saying red, blue and yellow). The primaries for light are the secondaries for pigment, and vice versa.
That was a great explanation of how we see light. I can't imagine how anyone ever figured it out. Thanks for making me feel stupid. 5 Srars all the way!

mmmm, why would be the green a primary color? even in the fact that red + green results into brown, not yellow.

IF there was a green star, the universe would go chaos and have white holes going into another galaxy, 20 suns in one planet.
I think this could be impossible.
It just looks like different colors when you look at the stars.

CV Canis Majoris is the biggest star we know, and is several times larger than our solar systems
Helge129 3 years ago
That is not accurate. It is about as large as the circumfrance of saturns orbit. Still pretty big, though.
PatrioticEagle50 3 years ago 3
no, it is several times Larger, in fact, even Betelgeuse is bigger than our solar system.

The color shift caused by stellar motion is too subtle to be seen by the human eye, so what you're seeing is probably mostly due to the atmosphere.
