Ring particles casting shadows

Cassini has photographed shadows cast by individual particles within Saturn's rings (look in the centre of the image linked to below).

We may need a 3-d model of the rings at this rate... 8O

Re: What if a space elevator broke?

Kim Stanley Robinson's novel [i]Red Mars[/i] has an interesting description of a space elevator collapsing onto Mars. You wouldn't want to be living anywhere near the equator...

Great update! Much more user-friendly than the previous version.

But lava IS grey, isn't it? (When it hardens.)

Re: Kraken Mare

I like the choice of sea monsters for the names. I hope we get a Nessie Mare.

RIP Arthur C. Clarke

I hate to be the bearer of bad news, but Sir Arthur has left this world.

Rest in peace, no-one did more to inspire young astronomers than him, I'd guess.

Is this possible with Celestia?

Re: ORBITER SPACE SIMULATOR style Jupiter

This is interesting but it makes Jupiter look awfully drab and dark. I'm not sure this is realistic. It would be nice to find an atmospheric effect that is close to yours but brighter.

Re: Cassini's Iapetus encounter 2007

Wow!

Steve Albers has made a new Iapetus map.

It'll work in Celestia if you offset it horizontally by 50%.

Re: Cassini's Iapetus encounter 2007

At last! A high-res view of Iapetus's bright side. This has been a long time coming. It's amazing, some regions look like they're covered in freshly laid snow. Iapetus must be one of the weirdest places in the solar system. http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-list.cfm?browseL...

Comparing Cassini and Celestia

Interesting opportunity for comparing Celestia's version of the Saturnian system with the real thing "Family Portrait" of Saturn's moons http://www.planetary.org/blog/article/00001126/ Celestia cel://Follow/Cassini/2007-09-09T02:56:31.28063?x=9oJDwmtWexqD/////////w&y=rnrgEgzDsZwD&z=E9oTGRLuX...

Re: Gas giant upper atmosphere

I guess this is the point to ask whether anyone's read Wheelers by Ian Stewart and Jack Cohen... has some rather odd aliens in the atmosphere of Jupiter, but you'd expect that from the authors of Evolving the Alien. That reminds me of Iain Banks's The Algebraist , which also has wheel-shaped aliens...

Re: Gas giant upper atmosphere

Actually, the story has no real plot, as I recall: the hero goes to Jupiter, sees some cool stuff, and goes home. The end. :lol:

By the way, there's a similar descriptive passage in 2010, where Dave Bowman flies through Jupiter's atmosphere.

Talking of real Io volcano movies, have you seen this one from New Horizons? It could be the coolest thing ever.

Re: Gliese 581 c Texture

All these images seem too dull (in colour, I don't mean they're boring!) If I was in the Gliese 581 system and looking at the star, would I really be able to stare at it like I would a glowing ember? Or would it be blindingly bright and hurt my eyes, even if less so than our Sun? If so, shouldn't it...

Orbits overlapping models + missing pluto orbit

I have two odd bugs. Planetary orbits are overlapping 3d models. See pictures: http://www.flickr.com/photo_zoom.gne?id=483312451&size=o http://www.flickr.com/photo_zoom.gne?id=483312439&size=o Specifically, the furthest half of the orbit overlaps; the nearer half doesn't. The effect only hap...
