Explanation: Where do the dark streams of dust in the Orion Nebula originate? This part of the Orion Molecular Cloud Complex, M43, is the often imaged but rarely mentioned neighbor of the more famous M42. M42, seen in part to the upper right, includes many bright stars from the Trapezium star cluster. M43 is itself a star forming region that displays intricately-laced streams of dark dust -- although it is really composed mostly of glowing hydrogen gas. The entire Orion field is located about 1600 light years away. Opaque to visible light, the picturesque dark dust is created in the outer atmosphere of massive cool stars and expelled by strong outer winds of protons and electrons.

Come on, man!
This isn’t real, it’s some artist’s or programmer/artist’s alteration of data by assigning some pixels or wavelengths or sumthin a certain color and others a different color. Cuz space is just black and white, essentially, and radiowaves and gravity waves got no visible color. Amiright?
Somebody got some splaining to do.
:)

I said that months ago on other astronomy images and some freeper yelled at me.
These are nothing more than digitally enhanced data packets.

Looks like the chestburster from “Alien”.
Here's the "splaining" you requested.
First, let's realize that "color" perception is in the brain. The light receptors in your eyeball's retina do not "see" colors, they register the impact of photons with certain energy (i.e. waves with certain wavelength (1/frequency)). Your receptors send signals (data) to your brain, and your brain interprets the data as "colors". There is nothing intrinsic about "color" -- it's just your brain's interpretation of some data from some receptors.
Second, there's nothing special about "visible" light, except that it happens that that range of wavelengths matches the sensitivities of your retina's receptors. Some animals can sense other ranges of wavelengths.
So third, there's nothing unusual or untoward about mapping wavelengths of light that our retina's receptors can't sense, into the "visible" range that we're familiar with -- it's just another interpretation of the data for our brain to use.
As for your claim that "space is black and white" -- you are both correct, and incorrect. If by "black and white" you mean "dark and light", you are correct, in that light intensities vary. But as I said above, the light that your brain interprets as "red" or "green" or "purple" is really just black and white also. It's your brain placing the "colors" on that data.
So if some astronomer assigns "visible colors" to certain wavelengths that our receptors can't sense, there's nothing "unreal" about it -- it's just a way of giving our brains something to interpret in familiar terms.
Make sense?

You took my post way too seriously. All of what you said is known, but not my point, which is, what some artist chose to make deep red, another might make it lime green, or egg-shell grey, but either way, it’s not what the average normal eyeball sees in outer space—these “astronomy pictures” are clearly just all contrived artwork.
