Sure. The main factors are a low sky mean altitude and a low sky ground density. The rest is playing with colors: the sky, the decay color and the haze all have a similar bright orange hue. To enhance this look, you can even use low altitude haze and fog, with bright colors. If you have different colors of the various elements, you can get some wild effects.
Very nice mood but I can't help that some non-scientific things are getting to me. I hope you don't mind me bringing them up: 1. The big moon is inside the rings. It can't be because the rings are expected to be at the Roche limit where a moon would be broken up by strong tidal forces. 2. The small moon casts a soft shadow on the big moon. It is unlikely since none of them seems to have an atmosphere.
Thanks! I don't mind at all. You should know that realism ranks only 3rd in my priority list when making an image. Beauty and imagination and 1st and 2nd. This means I easily sacrifice realism for the sake of the other two, like in this case. Regarding your points: I can't say anything about the Roche limit as I'm not familiar with that theory (nor am I worried with it for my images for the reasons pointed above ). Regarding the soft shadow, as far as I understand from eclipses, that's not caused by the atmosphere. That's the penumbra area, which happens regardless of atmosphere. See the diagram here: [link]
I know what you mean and the umbra/penumbra effect is caused by a non-point like light source even in a vacuum. An atmosphere blurs the shadow further and make the penumbra reddish. If you have a really big star very close you may actually get away with the softness you have modelled. My mistake. (very big,very nearby though )
