Description
A quick one, made in 1 or 2 hours, reusing assets that I developed for other images.Rendered in Vue.
EDIT: wow, my 7th DD!
Thanks a lot to for featuring it!

Every time I see this image I wonder how you created such a laser-like horizon! Would you shed some light on that?

Sure.

Thanks again for the tips Artur! The atmo I got from it is used in this scene: [link] 8)

Your work reminds me of the movie: Another Earth
I wonder if you have seen it.
I just love your vision

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.
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

I see. Thanks!
When you say "reddish", you're assuming an earth-like atmosphere, right? I suppose that atmospheres with other gases could cause a different color, right?
Another thing: what would be the effect if the inner moon would have a very low density? Imagine that it's hollow, for example. Would it still be physically impossible to stay that near?
I ask because, like I said, I don't know what is the Roche limit but I do know a few basic things from my physics classes. When I was making this image, I thought that that inner moon would have to have a really high rotation speed around the planet in order to compensate for the gravity pull. But then I thought about the possibility of it being hollow and so maybe the speed wouldn't need to be that high because the gravity pull would be much lower.

Actually almost any atmosphere would give a reddish edge to the shadow. The color is caused by scattering of the photons on the molecules of the atmosphere and the shorter wavelengths (=blue) scatter most because they are closest to molecules in size. That leaves the red ones to pass through and it would be similar for any atmosphere except for those with colored materials suspended. There only two colored gases. Bromine (reddish brown) and chlorine (green)but you'd need some really exotic chemisty for them to accumulate. They are highly unstable. Colored dust is a possibility. Emerald dust for example. Again, rather unusual conditions required for them to form.

I see. Thanks for the explanation!
What about my other question of the "hollow" moon? What do you think?
👍: 0 ⏩: 1
A hollow moon would be artificial anyway so that would work. It is only something held together by gravity that would be ripped apart that close to a planet. For example, the death star from Star Wars would be OK.

Somehow, that doesn't make me feel so bad about violating some laws of physics.
Thought you'd like to know that I just posted an image inspired by this conversation. So, double thanks!

Awesome work! You should do digital matt paintings.

Thanks! I thought about that already but I'll have to learn Photoshop first.

Arthur, your work never ceases to amaze me...!!! Instant fave!

Oh gosh I was tickled when I saw the shadows from the nearby celestial bodies. Nice attention to detail when you see how fuzzy the shadows are depending on the distance. But you get a strong sense of isolation when you see the figure standing there, staring at the open, shallow(?) sea and the grand heavens. I would feel just as amazed at the sight.

This is just so very beautiful, it is almost dreamlike.Very spectacular artwork Arthur.
