Celestia Forums

just as the subject says. not sure if chris is the webmaster as well and would like to know these things.

keep in mind the majority of those nasa pics are with the sun behind the probe, so there's little to no highlight of the outer edge of their atmospheres. i suggest looking for backlit images where you hardly see any of the planet to get a good guess on the thickness. http://www.windows.ucar.edu/tour...

i think my cachethomes.net address might not be working. could you try sending it again to codyraskin@hotmail.com? and as for including it in celestia releases, i was thinking of something along the lines of what you're doing, basically just changing the colour arbitrarily in the solarsys file. i'm ...

cool dude! i'd appreciate it if you emailed it to craskin@cachethomes.net i wonder why this hasn't become a standard feature by now?

yeh 656MB is about 655MB more than my email account will allow :P . do you mean 656K?

I wonder if it'd be too much trouble to simply add a

Penumbra color = [#,#,#]

line to the code so anyone could code in whatever color they wanted for their fictional planets. then there could be a line that determines how close a moon would have to be to be within the penumbra.

I remember there being a patch for an old version of celestia which turned lunar eclipses red. Is this a difficult thing to implement for future versions of celestia?

they're going to give you different results cos the magnitude method is an approximation (assuming stellar type to get abs. mag. etc.) while the parallax method is only as good as your ability to measure angles between stars. and the previous poster is certainly right about the number of decimals yo...

yeh unfortunately the US prefers to stick with the reverse date order to set itself apart from pretty much every other country in the world except barbados.

i'm pretty sure that bubble with a tail is what you'd see for a binary system, not a single star. As far as stellar wind is concerned, our local neighbourhood is isotropic, not unidirectional.

the first one is a moon breaking apart. but the complexity of the model makes skinning it properly in celestia pretty much impossible.

and another

it's still a work in progress

ok i've finished my MU Cas system. 7 planets. tell me what you all think. http://www.imagestation.com/picture/sraid39/pc4b349316f9af2aa8704a9bc90f8ee13/fd0a6b4b.jpg http://www.imagestation.com/picture/sraid39/pba3ebc7e5df8a698717e0e9d4960742a/fd0a6b48.jpg http://www.imagestation.com/picture/sraid39/...

I was under the impression that the stars in globular clusters were classed as Population II stars, the same as are in the halo and the central regions of our galaxy, with comparable (very low) metallicity levels and thus comparable ages. yeh this is precisely what i was getting at, the stars in cl...

Putting the larger systems in the outer areas sounds reasonable. Since globular clusters were formed at about the same time as the galaxy, the stars with eccentric orbits will have travelled through tne high density regions often. It seems likely that only a few planetary systems that happen to hav...

Perhaps occam's razor is applicable when it comes to questions of extraterrestrial intelligences. We have not yet encountered any such creatures, nor indeed any solid evidence of extraterrestrial life--perhaps life is much more unique and rare than some people think? If there are twelve trilliion c...

Whats the formula for finding the radius of a star using distance and apparent magnitude as coded in Celestia? or the general law as applied in physics... Stellar radii are guessed at from their spectral class, not their apparent / absolute magnitude. As far as the distribution of spectral types in...

but this won't predict eclipses properly i think (getting rid of the custom orbit tag).

PS: @erostosthenes ( what a difficult name!) you're also right I think, but this isn't it common to all moons in the solarsystem? actually no, this is unique to the earth moon system. you can work it out pretty simply for yourself. a=MG/r^2 and take the ratios of the acceleration toward the sun and...
