Ok here are my two questions...
1. A. Are our planets Evolving as there slowly sucked into the sun.. (Meaning... I heard that if the gases in the dead coral reefs started to go into the atmosphere it will set Global Warming into High Speed and if enough got into the air a Massive Lightning storm Could ignite the air into an atmosphere much like Venus is now, And with the Discovery of Ice on Mars the next planet After Earth, If the Ice were to melt, Which will happen as it get sucked closer to the sun an gets warmer could turn into an Earth like Planet) So I'm wondering if as the planets get closer to the sunif they one by one are going to go threw a transformation into the next step... And if so Do you think there is a couple of 100 thousand years for each planet to be inhabitable as it goes into the next phase???...
B. Could this be a formula for other systems like ours and maybe have more earth like planets forming and devolping now??..
2. I was watching a Discovery Channel documentary about the evolution of the planets and they say that we used to have hundreds of planets that destroyed themselves over and over growing bigger and bigger as they collided and merged, Well They say they're not sure why the Big Red Storm has been raging for 300+years. Could the storm be being caused by a moon size planet that may not have broken up upon the enter of orbit and is Slowly getting Eaten and devowered over centurys of time??...
Thanks for any insite into these subjects.. |

1A: Life on Earth began very soon after the solar system settled into planets - apparently just after molten Earth cooled enough to grow a crust (you can't have life on open lava).
The planets aren't getting sucked into the sun. My understanding is the planets will continue their approximate orbits even as the sun ages and transforms.
1B: Much of what makes Earth habitable to us now is the work of very different earlier life processes that lived billions of years ago. So just providing the right amount of energy may spark certain kinds of life but that does not create an atmosphere you can breathe any time soon.
2. Those early planets weren't like most stable planets we know today, more like moons and asteroids, and dust, lots of dust.
I think that's a good guess about Jupiter's Eye. This can't be an object orbiting below the clouds, but perhaps something recently impacted Jupiter (e.g. one of its moons) and the Eye will last 'till that's eroded completely. On the other hand purely atmospheric convections could explain it and there are a few good models. Saturn has a freaking Hexagon at one pole and a freakier Eye at the other, complete with Eyelids. |

I've seen pics of these, Yes they are Amazing and Puzzling at the same time...
How's a Hexagon going to form amongst all the Swirling effects around it..
And the Eye, it's looking at us and LOL saying "If you only knew, hehehe"

| Ok I just to my Friend from Lockhead again about when a sun grows, he said threw time and it's phases it gets larger and it's pull increases. Closer planets may get sucked up or just burn up, and Others may have there orbits moved over thousands of miles in the process of finding a new orbit which could also cause planets to go threw Great Transformations like from Gas to Solid or even turn from dead to living, theyre not sure the real effect just assume threw other galaxies veiwed how things have evolved in them and how things could change here. Just something we were talking about. thought I'd share... And wondered if anyone else has heard of this... I cant just take his or one persons veiw. |

what you're describing is when the sun goes into its red giant stage near the end of its life as a mainstream star, about 5 billion years from now
there is no increase of solar mass, just of its diameter, and for all intents and purposes the orbits of the planets can be assumed to remain more or less the same as they are now
so yes, at some time before that (but still several billion years from now) the earth will become too hot for life - i doubt whether we need to worry about that at this stage though, chances are that humankind won't last that long anyway

This theory is pretty well established as the explanation for the formation of the terrestrial planets (Mercury, Venus, Earth, Mars and the Moon). The situation may be a little more complex for the outer giant planets, but even these were probably 'seeded' by the formation of terrestrial type planets about ten times the mass of the Earth.

No. Absolutely impossible. It could not survive intact from impacting the planet. Even if it did, it could not remain in the outer layers of Jupiter. Moreover we can see that it is very clearly gaseous and is simply a persistent storm.

Could be stabilized by some much deeper surface irregularity though, don't you think? Our twisters tend to linger over parking lots and skirt water bodies. |

That's it. The Great Red Spot is right over a Jovian trailer park.  |

This idea has been proposed in the past. I believe the current thinking is that this is not a viable option. IIRC this is because postulated rotational speeds for the 'surface' do not match those for the Red Spot. Moreover, there is no real surface as such, so no irregularities are possible.

AFAIK an earth sized (but more dense and massive) planetary core has been proposed for Jupiter, which would be much too far removed from the surface to affect storms on the surface of the clouds IMO.
