| Even if non-visible wavelengths can't be added, I still want to air the suggestion of having a mode where the on-screen rendering is tinted to negate the color of the nearest star. So near a red dwarf, you could switch on this mode and all the planets would blue-shift so as to appear the way they would if the star were white, and conversely near a blue star they would red-shift. You'd be able to inspect the planets' true colors and get at least a basic impression of how things might look to a lifeform native to that system.

| Speaking of different wavelengths, there's this video explaining effects of relativity, ad it also describes such effect as Doppler effect.
I.e. when observer is moving at relativistic speed, objects in front of him will shift their appearance, and our spectral "range of vision" will shift accordingly into ultraviolet or infrared. Which means that if these effects are to be implemented, the spectral images will be needed too. Well, I suppose it will take A LOT of computing power, and there's really no need for that right now..

It has been discussed in this topic, so look there if you want more information.

| Imagine looking at a dark part of space and then swiping to the infra red spectrum and BAM there is an exoplanet right in front of you!
Or what if you moved into the gamma wave spectrum and saw what was happening around you?
Space Engine is showing us the visible spectrum and we can adjust the exposure that is great. But imagine the possibilities? I am no programmer. But I think personally to program ALL of this in a way that would work seamlessly with Space Engine would be pretty damn hard. Next to impossible considering CBR and such things.
Or perhaps this has even been suggested before? If it has I am really sorry for a duplicate thread and mods out there can kill this one if they so wish

| I have wrote this in rus-lang part of Forum and write here again:
I wish a projection of cosmic microwave background anisotropy if only in map mode. 
In addition to other things, its constancy can help to navigate in the universe.

| I have an interesting idea concerning different wavelenghts. In fact, 2 ideas...
One is to create a palette of colors representing multispectral values from ultraviolet to infrared:
----------------------------------------------------------------------------------------------------------------
The other is a palette specific for each wavelenght band:
In this second example, the distribution of colors should be different for each band, because otherwise they will look very similar to visible light, and we want something diferent but at the same time colorful, aren't we?
----------------------------------------------------------------------------------------------------------------
I think that an approach would be changing the hue of colors, for example:

---------------------------------------------
I forgot to say, the other wavelenghts would be black and white. Thermal vision for example. It don't need colors, just the dark (cold) and bright (hot) information. So for most wavelenghts color is not needed, so less work to do. For ultraviolet and infrared is more a question of changing hue.

Thermal vision is, almost always, infrared...
Living among the stars, I find my way. I grow in strength through knowledge of the space I occupy, until I become the ruler of my own interstellar empire of sorts. Though The world was made for the day, I was made for the night, and thus, the universe itself is within my destiny.

| For near and short wave infrared, use of colors. For thermal (mid and far infrared), black and white.

| Ah, but why the difference? Infrared is infrared, why not use a continuous spectrum like Visible Light has?

| Because not all infrared is thermal. From 750 nm to 3000 nm infrared light act very similar to visible light. But from 3000 nm to 1 mm, infrared is emissive. And because the definition of infrared itself is odd. There is not only one infrared, but several bands that act in a different way, such as the difference from x-ray to visible light. There is NIR, SWIR, MWIR, FWIR, VFWIR and also the new T-rays, that is between infrared and microwave, but act different from both, is a band of light itself.

Difference from UV, visible, NIR and SWIR.
Thermal infrared (MWIR and FWIR).
As you can see there's a big difference in the way that light behave from these wavelenghts.

| This is a cool effect I found. If you look at a galaxy while zoomed in from many Gly away, you can get some sort of effect. Is it X-ray? It would be nice to be able to see this without having to look on from a distance. (This is the Milky Way)

| I think this is the Doppler shift.
Don't forget to look here.
