Celestia Forums

Thanks, A. I used Celestia's default FOV (about 32 degrees) so the view's geometry should be reasonably authentic. Yes, the rings do get pretty thin near Saturn's equator. And, as you suggested, they spread out but also get more and more hidden by your horizon as you go toward the poles. I used Cele...

Here's one of the best short videos I've seen regarding whether the Universe is "flat" or "curved".

Interesting indeed! Enjoy!

After a period of "the doldrums" so to speak in the development of Celestia itself, Fridger decided to work himself on a newer more scientifically-robust version called CelestiaSci. Two other developers (dirkpitt and ElChristou) have now joined him. You can find out more on this page on th...

Thanks for the link, J V V. Went to the picogen site and was glad to see that it's also available for Windows. Then clicked on the site's link to the deviantart site and found many great examples of what it can do. Old or not, it's a program people are creating some superlative works with. Thanks ag...

Very nice images!

John V V, what program(s) can you recommend to produce images like your Mars-scape? Is it a 3D object?

TIME: The Indefinite Future SUBJECT: Celestia version 4.0 CAPTION: In what future historians would refer to as "Celestia's Renaissance Years", a new resurgence of development has taken advantage of emerging holo-beam technologies to project 3D objects viewable in true 3D, appropriately nic...

My thanks too, Frank.

Your contributions are always appreciated.

Here's another site that looks like it has data-sets and a lot of other info about Saturn's rings: http://pds-rings.seti.org/saturn/ It's part of NASA's PDS Small Bodies Node: http://pdssbn.astro.umd.edu/index.shtml Loads of info here about the rings of Jupiter, Uranus and Neptune too.

Thanks, Lodgy. For anyone interested, the Ciclops site ( http://www.ciclops.org/?js=1 ) definitely has a lot of great material, including loads of photographs that suggest how different Saturn's rings look from many different directions and under many different lighting conditions. As Chris Laurel (...

From the Ciclops site, here are images showing the considerable differences of the natural color mosaics of the illuminated and unilluminated sides of the rings. The top image was taken Nov. 26, 2008 "from 10 degrees below the illuminated (southern) side of the rings ". The bottom image wa...

Fridger, Because I have been quite familiar with the Ciclops data and had taken the time to read it prior to my last post, why do you resort to snide remarks like ". . . If you had taken a little more reading time, . . ."? As is so evident in your own 2007 post ( viewtopic.php?f=2&t=11...

Fridger, Yes, as the article states, the mosaic was based on the "unilluminated" side of the rings. Perhaps a way needs to be devised to assign different parameters to the illuminated and unilluminated sides. Either way, after comparing your photos of your 2007 post with the NASA mosaic, o...

Attached is a new Saturn-rings texture, which I created using the NASA image on this page: http://photojournal.jpl.nasa.gov/catalog/PIA08389 As the page says "This natural color mosaic was acquired by the Cassini spacecraft as it soared 39 degrees above the unilluminated side of the rings."...

Here's one of the previous posts about this: http://216.231.48.101/forum/viewtopic.php?f=3&t=11196&start=0 There has been more discussion but I haven't been able to find it yet. As I recall, Chris or Selden once explained that the Moon's orbit is just calculated and drawn at startup time to ...

Here's a beautifully done video with 400.00 galaxies based on data from the Sloan Digital Sky Survey. Enjoy!

To add a few words to Hungry4info's and Andy74's succinct explanations— pla879, yes, you multiplied everything by 2, but your examples start with numbers that are not powers of 2.
