NuclearVacuum's work

Not to hijack the thread, but I made a little exoplanet art of my own.

HR 8799


Blend of IR and Visible light images of HR 8799 to produce a pretty (unrealistic) picture.
Impossibly unrealistic, but sensationalist enough for Space.com to use if they want, haha.

PIRATE!!!!

No seriously, that is some picture. I find it very interesting that we found these planets at all.

Ever since I heard about a "rust water" planet, I got so many ideas. Here is my idea of a rust water planet.



Fresh water and Rust water
This is one of the moons of Iota Horologii b (the moon is named Lenin). It is about the same size of Mars, orbits its planet in safe outer orbit like Titan, and has similar conditions to Earth. The only difference is that its oceans of water are not lased with sodium and chlorine (making the salty waters of Earth), but instead mixed with iron, making the water rusty. This gives the moon a reddish-brown tint in its oceans.



Here is another one I did, but with a look at Iota Horologii b in the background.

I'd imagine that receiving slightly more energy from its star than Venus does from our Sun would have some nasty effects on those oceans...

I assumed that the oceans would give a brownish glow to the oceans (being rusty). But if I am wrong...

Thank you Edasich, now I have to compete with you!

16 Cygni Bb and a sunset



Here is my version of 16 Cygni Bb (which is actually a variant of John's). Here we see the planet from one of its arid moons. Star 16 Cyg A is setting in the atmosphere.

KABOOM!!!!



I am a sucker for close binaries. Anyway, here is my version of a collision of two planets in the BD +20°307 system.

I'll bet the more massive of those planets will get a moon (yeah... yeah... I know.... it takes a shallow angle impact).

I would compete with you guys as well but my Graphics card doesn't seem to be to be supported by my system anymore, so Celestia doesn't look all pretty to me.

Thank you Edasich. I am still new with Celestia, but I am not new to art. So I try to make my pics Celestia screen shots look like a real artist's impression. Sorry I monologed myself.

Anyway (since I have all your attentions), I wanted to get your thoughts on this idea I had. My favorite star is Vega, so you can understand that I would try to make a planetary system around it. When it comes to a water planet, I was thinking about this article I read recently (here). If plants are dark and non-reflective around M-dwarf stars, than the exact opposite should be for A-dwarfs. Plants that are bright and reflect most of the visible light (to the point that they can tolerate).



On this planet orbiting Vega, you would the star would reflect off the continents (as well as the oceans). Any life on the planet (if any) would be extremely different from Earth life.

As Edasich and I have pointed out already, adding Mie to your planets would make them look a lot more realistic. It's simple copy/paste to take the mie parameters for Earth and splatch them onto your planet orbiting Vega.

Though it may be that your computer isn't capable of supporting this. Look at the first page of this thread where I have several images of Earth both with and without Mie. Are you capable of getting the appearance of Earth with Mie (i.e. the enhanced atmospheric scattering)? If not, what version of Celestia are you using?

I copied the Mei from Earth and put it on my Vega planet. But I don't see much difference. I use Version 1.5.1. Why do you ask?




OMFG!!! I had no idea that Celestia 1.6.0 was out already!!!! Hooray!!



Here is the a Mei version with Celestia 1.6.0. Still don't see too much difference.

Your graphics card doesn't seem to support Mie rendering then. A shame, as it really enhances the appearance of a planet in Celestia.

Shame. But in my opinion, I really don't care. The planets I see are amazing to me either way.
