Using Earth Textures as Reference

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...

A number of issues...

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 ...

Re: Is there any way to add a "Dwarf Planet" class?

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...

Re: ROFL !

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 ...

Re: ROFL !

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...

Re: Realistic planetary generation

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...

Re: Realistic planetary generation

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...

Re: Drakaster - a sextuple star system

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...

Re: System Maker New version soon

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.

Re: Old Pictures from Celestia (locked)

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...

Re: Drakaster - a sextuple star system

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...

Re: Drakaster - a sextuple star system

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:

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.

Re: Panspermia

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...
