Celestia Forums

I've tried that... nearly an year ago.

See my double-ringed planet here.

The only problem I found were the conflicts between the planets' surfaces: drawn as polygons, they overlap each other.

Nope. Boiling point decreases as pressure decreases, but freezing point stays roughly the same throughout until you hit about 1000 Pa (0.01 atms). At lower pressures, it drops but there's no liquid phase. See: http://www.lsbu.ac.uk/water/phase.html for details. Wow. Commom sense took me way outta l...

And , to a planet that far from the sun, large cloud coverage would be unwise; it would reflect the so-much-needed light away from the planet. It would most likely freeze over: snowball pluto (er... like today) But then again, on a second thought: with a thinner atmosphere, the boiling point would ...

De novo, me metendo... Eh... I think I've already said this to someone, but let's try it again. * Not being mean, or corky, or anything like it * Instead of using 'solar system' to refer to a system centered on a star that is NOT the Sun, use 'star system' or the-name-of-your-star system, like The ...

instead of 1) jan 10) oct and then november (out of order), name them 01, 02, 03... 01)jan 02)feb and on...

... I was wondering about this 'cockpit' view and and I came up with this: http://img484.imageshack.us/img484/7515/2seccockpit7jg.th.jpg The green square is actually being rendered by celestia (not a montage[is this spelled right?]), as the logo image. I found out that celestia only uses multiples o...

Popular science magazines have a tendency of re-writing popular articles several times; Planet X is the one of the most rewritten story ever. A triple star system with a planet is interesting enough to be rewritten about every semester or so.

philosophical/metaphysics irrational and religious Certainly, irrational or religious POVs should not be discussed here. But as for the philosophical, I strongly recommend the use of philosophy in science boards. Philosophy is the mother of all sciences, the study of knowledge by itself. Maybe not ...

I've also read somewhere that Earth is a little bit past the snow line, and it's the greenhouse effect that keeps it as warm as it is. If Earth was further away from the sun, the greenhouse wouldn't be enough and we would fall back to Snowball Earth.

Ahem...

The Mpemba Effect

What about Pluto's new moons? Anyone has seen suggestions on the web? What could be decent names for those two?

Erebus and Tartarus? (areas of the greek underworld)

Cerberus and Sisyphos? (dwellers of the underworld)

Acheron and Cocytus? (rivers of the underworld)

I guess I hole through somebody's head would be more than enough wouldn't it? (That sounded evil, didn't it?)

hmmm... wouldn't it be possible to define the tail mesh as co-orbiting object (just copying the .ssc file from the comet you're trying to 'tail') and then set it's rotation period to match the comet's orbit period? If you could set [aphelion = tail pointing away] , then it would always point away fr...

In theory, it is possible. However, there are a series of practical issues that make the use o antimatter as weaponry a little too difficult. - Production: Nowadays one can only create antimatter using giant particle acellerators, where it is created in infimous amounts. - Storage: As the positrons ...

Instead of rotating the model, isn't it easier to change it's orientation, inside the .ssc file? "x20" "Sol/Earth" { Class "spacecraft" Mesh "x20.3ds" Radius 0.007 # Beginning 2448007 # # Ending 2010? EllipticalOrbit { Period 0.06903 SemiMajorAxis 67...

Infact, when the photon set out, it would be travelling though space that was expanding away from us FTL (no violation of special relativity. Well, that doesn't sound like FTL at all. The speed the photon is travelling will always be lightspeed, so it couldn't travel FTL. We ARE talking about a tim...

The first time I saw this pic I thought about the specular map. Is it a copy of the layer you used to make the pannels? (seem logic to be so, as the pannels are reflecting) But I thought something else; why cover a planet when you could put those pannels on space? Planet-based light pannels: - Only ...

Good one, nice thinking. Those names sound really good, so good I thought they were simply imaginated; took me a couple minutes to realize the pattern. Renni = inneR Elddim = middlE Tsrif = firsT Dnoces = seconD Retuo = outeR The last one I suppose it's your cat, as ailuna makes as much sense as anu...

The time will come when we will know many thousands of planets. When this day comes, we would have many more thousands of people spread across the galaxy, with different languages and cultural references. Even then, it would be easier to use computers and record names instead of numbers. A: Hey, le...

Not so much as for what we discovered, but as for what has been happening... Earthquakes, hurricanes, terrorist attacks... not a good year.

And as you said, still two months to go.
