| 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...

| 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.

| 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.
