Cool tutorial - very helpful to a beginner. 

When I added the blue stars option and messed with the sliders on the color ramp, I could get either blue or white, but not a mix of both. It looks like the same thing happened to yours. Is there a way to get different colored stars? 

Why when I connect the mix shader to the background it Turns pink. What is the reason?

Here is the node!👇🏼

As stated above. What method is there for exporting procedural world shaders and added objects (suns, structures, etc.)

Thanks!

I decided on using Cycles as it shows the displaced surface of my planet much better.  

The problem is, I lose the colorful glow of the sun that I have when I enable bloom.

Evee Render

Cycles Render:

 I get this awesome glow on the edge of the planet from the sun, but I'd also like to see that same glow on the sun that the Evee render has.  What can I add to the Emission Shader that will attain this?
