clouds are "fun"
now an "earth type" in a 3d seen easy BUT a map for a planet in simple cylindrical format ??? that is ... well "fun"

gas giants are different that "earth type" take a look in the tutorial section

Where o where do you get your cloud maps?

I like to get real-time cloud maps from here: http://xplanet.sourceforge.net/clouds.php

It is a cloudmap of Earth updated every 3 hours.

Don't worry about the subscription part, you can still get one for free by clicking on the first link in the first paragraph

I know you've said you use Rassilon's Cluster Generator for textures and stuff, but I have an older version, which doesn't include texture generation. (Same goes for his ssc generator.) If that's what you're using, how can I get my hands on an updated version?

I read elsewhere on this forum that there may be an attempt to restore Rassilon's directory, which should have the texture packs.

I don't know how that's turning out though.

However, I did tweak the browser-based ssc generator and made some improvements. It is attached to this post. (no texturs for it though )

Rassilon's directory on Shatters.net was recorded by the Internet Archive's WaybackMachine.
It's available at http://web.archive.org/web/200807012140 ... ~rassilon/

Here's my take on Kepler-22b. Until it is determined what kind of world it is, I've decided to represent it as a water world...

This is Earth, as it was 300 million years ago, the Pangaea supercontinent

Hmmmm.....

Maybe we might get a special early Christmas Present from the skies when the Mayan calendar ends this year.....

A stable orbit around Saturn, itself having moved into the habitable zone!

[Tegmine]

Could you imagine such a sight? As the other moons lose their ices, they would appear as gigantic comets, and the meteor showers would be, for lack of a better word, spectacular...

(to say nothing of the rings, of course.)

Not to mention, Saturn's gravity and their proximity to Saturn will most likely influence the shape of their tails, twisted by the planet's gravity.

Although, I do wonder if Saturn's magnetic field might also play a role in the shape of the "comet" tails?

Anyways, new pics:

Lovely pictures PE.

Kristoffer,
I d?dn?t find an addon of Earth Pangeia in index of extras.Is it available or will be available at Motherlode?

SemiMajorAxis of The Moon 300 million years ago, is 13799 km

I got the map from devaintart.com

Unfortunately, a linear approximation using the current recessional speed is unlikely to give the right answer when extrapolating for long periods of time: the tidal forces differ depending on the distance between the Earth and the Moon, resulting in changes in the recessional speed.

[ajtribick]

There's also the issue of the configuration of the continents leading to different tidal recession rates due to varying dissipation in the oceans. As I understand it the recession rate at the current time is unusually fast due to a favourable continent distribution.

[MiR]

I agree with Selden and Andrew.
J.T.K. is also right in relation to a current value. And I think it's a good reference point for further calculations. Taking account of what Andrew and Selden wrote.

You might say: In general, the farther one travels through time in the past, the faster the rotation of the Earth, the slightly smaller is the value for the distance Earth - Moon. The reasons are pretty self-explanatory.

@Kristoffer
(actually the main reason why I post here)
I Don't know if you still interested; I've found this page with very good paleomaps (and others...)

Dirdel and Binary, a binary planet I've posted a few times before:

Here, I bumped up Binary's Size and adjusted the orbits accordingly to maintian the double-tidelock.

The system's innermost planet: The Swamp Planet of Evil, now with an evil red tint.... The moon retains an atmosphere in spite of its exceedingly small size -- a radius of merely 800 kilometers! The atmosphere is held in place by advanced technology.

View of a polluted Earth

Set in the year: 2040
Population of Earth: 7.5 billion

From this, the climate on Earth changed rapidly, maked the Earth uninhabitable without oxygen masks
Entire Earth lost it's oxygen
It's just a story

On this picture you can probably see USA, but it's not so easy

[PlutonianEmpire]

Now that is a beautiful solar system.

Perfect mathematical harmony. (At least, that's what it seems like. I could be wrong, lol.)

The innermost planet's orbit was based on the Kepler-16 model.

[PlutonianEmpire]

If any of you have my Delta Trianguli addon that I uploaded to the motherlode, you may be pleased to know that I improved Lethe's appearance, for the most part.

I hope I made the cracks in the surface, especially the ones hidden from view in this screenshot, more sinister-looking.

It will be included in the next Delta Tri update.

Here are the 3 new planets I added to Delta Tri.

Psychedelic, maaaan! Probably the most "psychedelic" planet I've ever created. This is the innermost one. Name is Hadeia. The best part is that the second sun still isn't bright enough even at this close proximity to cause the atmosphere illumination to skip to whichever sun appears brighter.

hadeia.jpg

The one between Belle Hades and Hadeia. Yes, this one's lavender too. Name's Plutono.

plutono1.jpg

Hadesia. Volcano world. Bigger than Venus, smaller than Earth. Furthest from suns. Toxic atmosphere, obviously.

[Tegmine]

Grooovy!!!! Here's my take on Kepler-20...yes, I'm finally getting around to making textures...nowhere near done, though.
