Celestia Forums

The Big Bang didn't originate here , it originated at the point from which all galaxies, stars, clouds of dust and gas have expanded away from. Yes. And if you rewind things back, you'll find that "here" is the same for every point in the universe. Going back in time, everything retracts to a singl...

A hires image from today's close flyby has been put on the raw images page. I thought they'd be put up tonight but evidently some are coming through already http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-details.cfm?feiImageID=34871 I'd prefer something with more shadows on it, but you ...

Sadly, the brightness of a nebula is the same no matter how close you are to it. Although the total light increases as you get closer, it's spread out over a larger area on the sky. The two effects exactly cancel one another :( How about if stars are illuminating it though? Wouldn't you get nebulos...

While it is a very fine image, the problem is that gas giant atmospheres - on the small scale - change all the time. Bands and large structures may generally stay the same, but it's obvious with Neptune and Jupiter that spots and storms can come and go. Saturn IS a little more stable-looking, but at...

Contrary to my original offer, my TextureFoundry /WEBsite/ will not be revived/updated. The reasons have been widely discussed, as you will remember... In fact, that URL is not really the place where I made work of mine available for download during the last few years. It is an FTP-dir 'close by' h...

Fridger - I should point out that your WWW link under your messages points to your work webpage (which has no celestia-related links on it), not to your Texture Foundry - surely pointing to the latter would be more useful for people here?

Indeed, since Celestia development has been stagnating for many weeks Which is a bit of a problem in itself really. I realise that Chris has other things to do besides work on Celestia, but it's been quite a while since we've heard any news of development of a newer version of Celestia. New texture...

Those are pretty nice pictures! Good work!

It happens on my system after landing on the Earth with a Ctrl-G when I reduce the distance to relatively small values, less than 2 meters. I think it's related to Celestia's clipping plane problems. The symptoms (distance from object and severity of the bug) are different on different graphics car...

what do you mean by 'bucking wildly' and 'jumping up and down'? Like, you're happily on the surface and then suddenly for no reason your view starts shifting up and down rapidly? If so, I can't say I've ever seen that happen before myself so I'm not sure what could be causing that...

Yeah, what stars are you referring to? Granted, there's a bit of variation in the radii of stars as it is (another star with one solar mass may not necessarily have exactly the same radius as Sol), but I can't think of any low-mass K or M V stars that are bigger then Sol.

What you should be doing to land on a surface is getting the place on the planet you want to land on centred in the view (press Ctrl-K to show markers, if necessary - that's where you'll be landing), then pressing Ctrl-G to go to the surface, then pressing Ctrl-F to go into alt-azimuth mode which al...

Given that every Jovian world in our system has rings of one type or another, would it be a logical assumption to say that at least most gas giants around other stars have rings as well? Would having rings be an inevitable consequence to being a gas giant? I realize that we can't say with absolute ...

This is one awesome pic!!!!

Knew I was forgetting something obvious... This is one of fridger's binaries, from his file that he's linked to now, just to show you the general format: Barycenter "13 Cet" { RA 8.811004 Dec -3.592758 Distance 68.652286 } 2762 "13 Cet A" # component A { OrbitBarycenter "13 Cet" SpectralType "F8V......

Is there an add-on to allow multiple star systems, like Albireo or Mizar, to orbit their centers of gravity? Or an add-on for an individual multiple star system? To actually answer your question, yes there is. It's only available in 1.4.0pre6 - you can download that from this link This supports mul...

That mountain belt region on Ghelllonius looks a bit too sharply defined to me... is that deliberate? There's no border between that and the green regions to the north and south. The dark patch on Amycos seems a bit odd too. It looks like it formed as a result of the crater impact in the middle of i...

And let's face it, getting out and about in the great outdoors is much better for you than spending all your time chained to a computer .

Why would it be "most likely" to be blue with few clouds?

It's Saturnshine on the left, but the background is overexposed space rather than Saturn itself. If that is so, how could the dark part of Enceladus possibly be that much darker than space? Matt has a point there :). It's got to be Saturn in the background unless.... hmm. Maybe Anders might be corr...
