Celestia Forums

My searches for an Earth coastline map released in creative commons with attribution I could trust or use without much fumbling has been generally unfruitful so I decided it would be best to do my own map and base my version on the textures of the Earth made available here, namely a "4kEarth.pn...

Peculiar thing: http://www.maj.com/gallery/Dracontes/Scans-and-screens/glitch_openoffice_thumb.png Maybe this'll give a new boost to the idea of merging *.stc and *.ssc by forcing a choice, though it's true I can open the files in WordPad as it was before I installed the OpenOffice 2.0.2 suite. I'm ...

Well, see for yourself: http://en.wikipedia.org/wiki/Definition_of_planet http://en.wikipedia.org/wiki/2006_definition_of_planet The gist is that it's holding fast, though it may need some refinements in the long run. As a matter of fact, though I wholeheartedly agree with the decision, I altered th...

Yeah, right! :P Where did all that mass come from anyway? Well, it's simple : the mass didn't changed, obviously. Only the density changed (I'm taking the view point of that funky guy ! :wink: ). So in the past, Earth's density was higher. Because of the high internal pressure and temperature, the ...

Oh, that's when a hole rips open at one of the poles and the planet goes flying out of orbit at uncontrollable speeds, making a "phhthppppp!!!" noise the whole way. Good one :D Actually I took some time to do the math just 'cause I can and I found absolutely hilarious the guy thinks it true that th...

It's easy to put planets and moons anywhere and Celestia's not going to care. That's one of the reasons why I prefer to do the math work myself, educated guessing from fooling around with numbers becomes second nature with time :wink: I'm not certain which of these formulas on these two pages are m...

As you can see by this screenshot I use a spreadsheet with a whole lot of calculations done. In fact, this particular *.xls file is close to 1 MB, may that excite you or not :wink: If you want it quick and more or less dirty you can go with the generators. I however can't afford that given the pecul...

This time I fancied zipping the *.stc and *.ssc inside a folder and preparing a download page at my incipient site would be a better idea. So to spare people time, I mean. I added moons, corrected the radii of planets relating to more accurate estimates of their density. Also, for your viewing pleas...

It's a good idea but it still needs some work: (Note that some of these may have been repeated by other forum members) - A tree-like hierachy for bodies - Inclusion of a *.stc editor (as Dollan said) - Better ordering of object characterizers. Say: +Movement |- Elliptical Orbit |- Rotation Instead o...

Perhaps a long shot: pen tablet support (in Pen mode). I can use my Wacom in Mouse mode with Celestia but it's an ungainly affair.

I've not been here for quite a while so... I'm a Life & Earth Sciences student at Universidade do Algarve in Portugal so that includes a lot of class attendance and preparing for performance evaluations. I'm an amateur artist , which includes bouts of creativeness as my disposition wills, and th...

Uh, might as well... I've found out that the ability to orient objects in Celestia and to zoom in on them gives some interesting results. Well I think they are... These were all made with the basic Celestia 1.4.1 package. http://www.maj.com/gallery/Dracontes/Scans-and-screens/deimos_et_phobos_rszd.p...

Thanks for the pointers, Malenfant :) I've just finished the spreadsheet using those formulas, this time correctly, even going to the trouble of including the error margins. Numbers crunched, it seems I won't have to change things too much. The only hassle will be splicing these calculations into my...

From the little write-up I made to set my goals for this system's design, I had it as originating from a massive, dense protostellar nebula that collapsed into these stars more or less where they are today. I don't have any pretentions to the likelihood of that happening, I just need the inkling tha...

You could always set the font colour to black and have people who would like to read the text to highlight it, such as below:

-->It wouldn't be too different from having [spoiler]text[/spoiler] IMHO and it's an already available feature.

Thanks very muchly for the links and formulas :) That Snow Line formula is one I'm quite keen on :D Actually this is the second time I've done this. Drakaster's previous incarnation went defunct this Summer on account of a computer malfunction and subsequent fixing. But a brainchild never dies... It...

Screenshot http://www.maj.com/gallery/Dracontes/Scans-and-screens/drakaster_1_thumb.png STC file Just right click, "Save target as", and substitute filetype "txt" for "stc" in the prompt, or if you want to look at the code right click, "Open in New Window". It's not a terribly original name for a s...

I like this one better. http://arcbuilder.home.bresnan.net/PCL01.html and it has pictures :lol: Rendered in Celestia I might add. Actually I rather like it that he used mass cutoffs for classificative purposes and the terms "planetesimal" and "planetoid". Rather more succint than "small solar syste...

While constructing my own stellar system I noticed the lack of a few things that would make my work easier, and every one else's for that matter, in terms of visualization: - Toggle on/of display of orbital parameters: semi-major axis (as a straight line), ascending and descending nodes (small circu...

Taking this seriously :wink: I'd think the question is spurious until we find good evidence, as are chemical signatures, that life existing on Mars, if there ever was such a thing there, is related to life on Earth. Until then questions such as these are better seen as diversions from the main subje...
