Some old and forgotten lonely fellows...

Another one... just for fun.

Can I still post my creations in the main Pics thread, or do they now go to the custom Sci-fi thread?

There's no "have to" in this regard. Since Cham started the "Custom" thread, I'll leave it to him to comment on what competition would be appropriate there.

Well, there aren't any much rules here.

I was expecting regular pictures (real probes and spacecraft, planets and their moons, black holes and nebulae, for example) to be shown here, while fictious (i.e. science-fiction and fantasy) scenes could be shown in the other topic. By "custom", I was thinking about original creations (non-Star Wars, non-Star Trek, etc...).

Rassilon creations could be a good example of what I call "Custom".

Asteroids around an exoplanet...

I couldn't get Runar's beautiful Saturn add on to work on my setup so I recoloured the default texture, added clouds... also using Mr Fridger's lovely ring texture.

I like it.



Clickie for biggie.

Nice. Tender, weightless, floating,...

Coming soon, to an eastern sky near you!

At sunrise in early October, the pairing of Venus and Regulus.

Hopefuly this is what I should see from my hometown location at 05:00 UTC over 4 consecutive mornings, with the highlight of the closest pairing occuring on 3rd October. From the east coast of America the two bodies should be as little as 1/8 of a degree apart.

the KOI-500 planetary system with 5 planets
and also comparison of the orbits of the 4 inner planets of our solar system. I added the 4 inner planets, Mercury, Venus, Earth and Mars to compare their orbits with the KOI-500 planets orbit. The KOI-500 star is 3/4 the size of our Sun, also sun-like

KOI-500 is 1,100 light years from our solar system

One thing I like about Celestia 1.6.0 and 1.6.1, is that you can go 2 whole billion (with a b!) years in the past or future. And with some trial and error, and taking advantage of what the timeline feature is currently able to do, I managed to build an SSC that literally updates the Earth in real time from 850 million years ago to the present. The best part is, I had an older version of the paleographic maps found in CML's scripts section, that did not have the lousy writing on them.

For up to two and a half million years in the past, I used the timeline feature for Earth itself, to try to smoothen the transitions between the built in orbit and rotation models and the regular SSC defined rotation and orbit models. For the rest, I used completely separate versions of Earth, each with their own beginnings and endings, since timelines can't support texture changes.

Of course, the Moon is dead as a doornail, so I timeline'd it the whole way through, recentering it to each new Earth period with reference frames.

Anyways, a pic.

Very interesting! Great idea!

Could you share your ssc file?

Just messing around with various addons

Pretty! Which addon is that?

Plenty of addons

The white planet in the left lower of the screen is Planet X, with a texture that exist in Celestia. The green planet is Bonandi, that's now orbits around Planet X. I made the background by using some fictional nebulas. You can also see the California Nebula.

Prototype for a Saturn's interior, mixing 3D and point sprites

Accordingly with this paper

"the flux is confined to rotating columns around the rotation axis", there is "no vertical motion along the columns" but a secondary atmospheric circulation is generated "in form of counter-rotating cylinders concentric with the rotation axis". In the pictures, the 4 (there are 8 to simulate the "cross-section") cylinders rotates about the planet's axis with alternate verse - clockwise and counterclockwise - respectively, meanwhile the columns rotates alternatively - clockwise and counterclockwise - respectively. This is supposed to generate bands and jets, which mechanisms are developed through different approaches.

Ola,
Do you have other sources ?
They said that density is constant (???) and they speak little of gravity...

When this article was published there ?

Physically, it's hard to believe this...
