(Thanks to PRD)
Here is a quickly done demo of Atmospheric Rayleigh scattering shaders from space.
The colors are calculated by the shaders. The only things in this demo apart from the shaders is the lens flare and the skybox.

That song sounds familiar, mind sharing its source?
Music is from Ruitchi Sakamoto, music from the movie “Merry Christmas Mr Laurence”. Great Japanese composer.
A good start has been posted by PRD in the shader lab forum, search for “atmosphere”.
He has ported the Neil version of the Scattering/Mie algorithm on Unity for a project he made for the NASA and I managed to modify it to make it more user friendly and more nice looking…
Nikko
you always surprise me . Good work

I really like this, its almost hypnotising.
Very nice work 
Remembered where I had heard it.
It’s also in this video.
Can I ask what specific changes you made?
I think this is superb. Your posts are always very interesting. Looking forward to seeing a demo with this and your hi-poly ship combined.
What else do you have up your sleeve I wonder…
Cheers,
Matt.

Are you sharing this? Because I need a multi-planet atmosphere shader for my game!
