Very nice work, P.E.!

Last shot for now...This is one of Srira Viti, its parent planet Cotralege Mu (thank you AstroSynth name generator for such wierdness) and just over the limb, Tegmine C,D and E (D and E are so close they look like 1.)

I'll try and present some new material soon...

Tonight, I learned how to make my own custom galaxies with Gimp! :D

Another cool thing I learned, the larger the dimensions of the template .png, the prettier and more detailed it looks in Celestia! :D

Very nice work, PE.

Having a penchant for Earth-like worlds, here's one I recently did...(Credits: Selden's modified StarGen, Wilbur, GIMP and a gradient editor by somebody...)

There are few highlands on this world. Heavy rains produce extensive silting, but it could also be a form of algae not yet described. The oceans themselves are shallow, perhaps a couple hundred meters at most. Continents are completely covered with plant life, making this world a very tempting target for explorers...

I don't have a lot out there...just the first Tegmine addon. I'm a very slow worker, so it might take me some time to get something together. But I'll try and get some of them out there....(of course, I'm worried JVV will pan it and it never gets posted... :roll: )

But thanks very much for the compliment!

Look what AstroSynth gave me for Kepler-47c! Image

4_lolhueg_moons.jpg


Four huge moons! :lol:

In AstroSynth's defense, that earth-like one was from the depths of my own brains. :mrgreen:

The rest are minor moons and 3 Ganymedians. :)

Very nice, PE! Which version of AstroSynth did you use? (I'm still using the demo version of AstroSynth 2.0) I used it to create the Tegmine system, actually. (However, I did have to do some editing.)

A long time ago, I made a planetary system which I put around Theta Persei A. Here is a shot of the 6 worlds, done mostly to scale...(The gas dwarf is about twice the distance in the shot so it could reasonably fit...)

Same here, actually. I'm also just using the demo version of 2.0.

How Kepler-47c got that moon system is because I find the number of moons generated for small gas giants to be pitiful at best, so after putting in -47c's radius, and adjusting the density to make it match the mass indicated in extrasolar.ssc (130 Earths! 8O ), I moved the decimal point one digit to the right to artificially inflate the planet's mass so I could get the maximum number of moons the demo can give me (25), but at the cost of the first 18 - 20 moons all being "rings", and so I used the ring width's to use them for the moons' radii, editing as needed, and the rest is history. :)

I wish there was a way to put the AstroSynth output into an .ssc format, it could make life a little easier on the addon front. (Yes, I admit it. I'm a horribly lazy person at times.)

Here's a real-world planet with a hypothesized moon...HD 221287 has a planet in the HZD, about 3 times Jupiter's mass. Orbiting is a moon about .09 Earth masses, but possessing a dry, tortured surface. Any water is locked up in ice.

This brings me to my next question...what's the scaling law for satellites? (As simple as possible, please; math was never my thing.)

I creating my own sci-fi worlds

This is a habitable desertmoon, called Auriga. Auriga is some way familiar with Mars, but it is hotter, so it is a Hot-Mars. but in size, it is larger than Mars. It is orbiting a gas giant planet called Hephaestus. Hephaestus is orbiting a real star, Psi5 Aurigae, 53.9 light years from our solar system, in the Auriga constellation.
http://en.wikipedia.org/wiki/Psi5_Aurigae
And there is living a civilization on the moon Auriga.

As I will say, this world will be part of a sci-fi story I'm writing on :D


The population of the Auriga civilization are just a few millions of them.
They are between 30-50 million.
You can see there are intelligent life there, if you see on the night-side.

I think someone posted a while back that they were trying to make an exporter utility for just that.

(Yes, I admit it. I'm a horribly lazy person at times.)
Me too. ;) Except it's 24/7. :P

I was looking at a collection of old CD-RW, and apparently, I found a full, complete stash of old addons from Rassilon (already aware of the directories on archive.org, but I have a 4gb internet data limit. :( ), so I figured I'd try my hand at updating them to 1.6.1, and to more recent data too, as well as hopefully better physics. :mrgreen:

So far I did three addons, with some success, Eta Car, V380, and Toliman.

Here's screenies of the latter two:

And, I decided to apply a pre-existing texture to the new planet around alf Cen B, and used the browser-based ssc generator for randomization, and it looked nice, IMO. :)

I have a somewhat similar set up with a binary terrestrial, but the similarities end there. :)

Image
Dirdel and Binary, are home to a fiercely democratic, yet highly religious and xenophobic (and oddly, huge tech nerds) insectoid race, who originated on the primary (Dirdel), colonized the secondary (Binary), and geoengineered both worlds to reduce the temperature extremes caused by the tide-locked pair's very high obliquity.

Plus they are in a circumbinary orbit around two suns. :P

Very nice work, you two!!! Eburacum, I'm gonna guess that the world on the left of the twin worlds is the closer of the two in this shot, (am I right?) Still a very cool concept, although the tides on such worlds would be fierce beyond measure.

This world was created, using, of all things, a paperweight made from Italian marble. It was sitting on my desk, and the more I looked at it, the more I thought it would make an interesting planetary texture...

Wouldn't the tides stay in the same place, since they're tide-locked to each other? I've figured that since both objects stay in the exact same position in each other's skies perpetually, the tides pretty much wouldn't go anywhere. Probably the only mobile tides would be the ones caused by the sun(s).

That's my guess, anyway. :)

Did the name for this world happen to stem from a certain character in a certain.... American.... movie? Image

Anyways, I actually kinda like Celestia's (and my computer's) ability to render interesting shadow plays in trinary systems. :)
