So, let me understand. You basically skimmed through the stuff you disagreed with so that you could get to the stuff that told you what you wanted to hear. That response is just weak, and I can't see what you saw in it.

We know for a fact that Jupiter has loads of internal energy, which he entirely ignores. In fact, there's about 60% more energy radiating off the planet than could be explained by the Sun alone. He also spends a bunch of time talking about the Great Red Spot, which actually makes the other guy's point: it's pulling hot air up from Jupiter's depths, where it can be observed.

Jupiter radiates more energy into space than it receives from the Sun. The interior of Jupiter is hot: the core is probably about 20,000 K. The heat is generated by the Kelvin-Helmholtz mechanism, the slow gravitational compression of the planet. (Jupiter does NOT produce energy by nuclear fusion as in the Sun; it is much too small and hence its interior is too cool to ignite nuclear reactions.) This interior heat probably causes convection deep within Jupiter's liquid layers and is probably responsible for the complex motions we see in the cloud tops. Saturn and Neptune are similar to Jupiter in this respect, but oddly, Uranus is not. [src]

So I think it's safe to say that the Skeptical Scientist is correct: Jupiter's weather has more to do with Jupiter's internals than the Sun.

The other guy's discussion of Neptune leads me to believe that he thinks that any change in a picture must be attributable to the Sun, and also be evidence of warming. Pretty lame.

As the Skeptical Science mentioned elsewhere, there is no observed warming of Jupiter. There is a predicted change in how heat is distributed, based on modeling of some surface phenomena.

As another respondent in the same thread pointed out:

I find interesting that "skeptics" so eagerly recommend taking the enormous amount of highly accurate data available for Earth with a grain of salt (or the all shaker for that matter), while at the same time accepting wild conclusions on poorly understood extra-terrestrial "climates" based on very scant, spotty observations.

Finally, and most important, given that the energy output of the Sun hasn't increased over the last 50 years of direct measurements, what mechanism is responsible for this supposed heat wave?

Neptune will never "suck up" Pluto. They are in a 3:2 mean motion resonance, so although their orbits cross, they will never collide.

http://www.nineplanets.org/plutodyn.html
http://en.wikipedia.org/wiki/Orbital_resonance

Jupiter is a lot closer than Saturn and we just did exactly that with Cassini-Huygens. It'd probably be a few years before we'd be able to but it's certainly possible.

There would definitely be some technological hurdles we'd need to cross but again I can't imagine they would be impossible to get around.

"The earth is just too massive."

I just flew half way round it in one day, it's not as big as you think. We have instruments that can detect a tide in a teacup, a large dam or open cut mine can be detected from orbit using mass distribution (ie: a gravimeter). But unless you have managed to solve the three body problem there is no way of knowing what affect(s) such a small change will have other than local tectonic movements. If an everyday goods train can make my house shake enough for the windows to rattle then 9.43 cubic miles of water will definitely have some impact on the surrounding geology.

I doubt it - the moon rotates on its axis precisely once per revolution of the earth, so the part of the moon facing the earth always changes. As a result, we can take see just over 50% of the moon's surface [ref: http://www.nineplanets.org/luna.html] from Earth. Pictures of the far side must be taken by a lunar satellite.

And what ever you do, DON'T pick Mimas as the planetiod... That's no moon!

You're in exactly the same position I was in four months ago, though with more budget. Although I'll give you the same advice I took:

Start with binoculars. I spent a grand total of $140 on a pair of 30x80 binoculars, and put them on top of a $30 camera tripod I already had. Very inexpensive start. Binoculars make it easier to find objects because they have a wider field of vision, so they're great for beginners. Also, if it turns out that astronomy isn't your thing, it's a much softer blow on your pocket. With much less than your budget you could get a much nicer pair of binoculars and a better mount. Starting with binoculars will also let you decide if you're more interested in observing lunar vs. planetary vs. DSOs (deep sky objects), which is a decision that can impact your choice of scope later. Binoculars are also great even if you have a scope, especially if you're doing photography. They let you keep looking at the sky while your camera is taking the picture!

For a $1000 budget I wouldn't try for astrophotography yet. Concentrate on getting a nice telescope first. If you start with a cheap scope you're more likely to get discouraged or disappointed after a while. Seeing as how you will want to one day move into astrophotography, though, make sure you get one on a german equatorial mount. You can't take long exposures if you don't have an equatorial mount -- with other mounts, even if the scope tracks the sky, the view will rotate within the eyepiece.

With your budget, a standard newtonian will get the most bang for your buck. You might start by taking a look at Celestron's Advanced Series. You can get a 6" for $800 or so, and an 8" for just over $1,000, complete with GOTO mount and tripod. Although if you know you're more interested in viewing planets, I see that Zhumell has a 6" refractor for about $800. Refractors are generally regarded as better for planetary viewing.

Also check out www.astromart.com for used equipment. There are lots of amateur astronomers selling their scopes to help afford upgrades!

A real must is a red flashlight -- red light doesn't ruin your night-vision, which can take up to 30 minutes to fully get. Go out with a white light, and you ruin 30 minutes of night vision every time you look at your star charts.

Also get a planisphere to help learn the constellations, and a sky atlas for help locating objects.

For software, the new Google sky is great, as is stellarium. I've also located a free package called Cartes du Ciel that is great for printing out sky maps.

Also, check out www.cloudynights.com -- it's a great source of articles and reviews, as well as friendly forums. Another good resource I've recently found is http://obs.nineplanets.org/lm/rjm.html -- if you're logging your observations or just want to talk about them on CloudyNights later, that page has a method to help determine how good your seeing is. Also, look for a Clear Sky Clock http://cleardarksky.com/csk/ in your area to help you be prepared for good/bad nights.

"let's let them nuke Israel...[ killing ] two birds with one stone"

The more likely senario is Isreal would nuke Iran and possibly serveral other Arab nations simultaneously (re: the six day war). The problems in the middle east (and other oil bearing locations, like Sudan) are caused by the veto wielding members of the UNSC bickering via proxy wars just as they did before Reagan "defeated the commies". Ironically the UNSC is politically similar to Iran's "revolutionary council", both are justified by power gained from winning a conflict, both "ride shotgun" over a (more or less) democratic institution, and both are composed of factional warlords, both use "fanatics" to do the dirty work.

Since Hamas won the (rare but fair) election in a landslide victory, "the people" have been financially ostracised by all veto-holding members of the UNSC. IMHO it's because Hamas do not fit into private agreements the UNSC members have amoungst themselves. I belive they have already decided that Isreal will get the west-bank and Egypt will get Gazza, Hamas winning a popular election just wasn't "in the agreement".

Comparing Ima-DinnerJacket to Hitler is hyperbole and completely ignores the last 60yrs of geo-political history.

Disclaimer: Everyone has an opinion but what matters are deeds, I find it instructive to step back and take a look at the "deeds" from a higher perspective.

What is the evil plan behind the acquisition of a huge icy moon weighting almost 18 millions billions tons? Easy. Move it in Earth orbit and threat your competitors to crush their headquarters with the power of millions of H bombs if they don't hand you ONE HUNDRED THOUSANDS BILIONS DOLLARS!!! MhuuahahahAHAH!!!

I can understand that if we found liquid water elsewhere in the solar system it should make news, but who cares about liquid methane? Afterall Jupiter (http://www.nineplanets.org/jupiter.html) has "exotic" liquid metallic hydrogen and liquid helium. I doubt it is possible to drive any biologically important reactions at the temperatures present on Titan. We simply confirmed that our knowledge of the methane phase diagram is correct. Let me know if they find something useful, like platinum or palladium on Phobos...

Two different measures. You're measuring radius vs diameter. But then again, I made a NASA mars probe mistake, and was comparing KM for the moon to miles for Mercury. Oops.

The Moon:
3476 km in diameter, 7.349E22 kg

Mercury:
4,880 km, 3.30E23 kg

Mercury's 40% larger in diameter and about 5 times more massive.

You'll be learning a new planet every year from now on too, if you keep Pluto within the definition of a planet.

You'll be learning a new planet every year from now on too, if you keep Pluto within the definition of a planet.

As such:

Pluto is locked in a 3:2 resonance with Neptune; i.e. Pluto's orbital period is exactly 1.5 times longer than Neptune's. Its orbital inclination is also much higher than the other planets'. Thus though it appears that Pluto's orbit crosses Neptune's, it really doesn't and they will never collide.

http://www.nineplanets.org/intro.html

That should be www. eight planets.org

You are incorrect as to why the planets are on the same elliptical plane.

http://www.nineplanets.org/origin.html
#3 on that page is the step which explains why the solar system is on the same plane. Pluto being outside that plane is most likely it is actually a kupier belt object and was far enough out from the formation of our sun to not have fully fallen into the accretion disc.

More information is available at http://en.wikipedia.org/wiki/Accretion_disc
http://en.wikipedia.org/wiki/Protoplanetary_disc

The reason your explanation doesn't work for why the planetary bodies are on the same plane is because they are all in stable orbits. To plane out into a disc they would need to still be falling towards the sun.

Planetary rings are in the ring pattern because they follow the orbit of the object from which they were created, they are not collected and built up from smaller particles but probably the result of the destruction of a large object.

The atmosphere of Mars is 95.32% carbon dioxide.

Why is Mars not a warm planet?

http://www.nineplanets.org/mars.html

For extra credit, does the measurable increase in ocean temperature mean that the oceans are less able to absorb CO2 or do the oceans start releasing sequestered CO2? Are we positive that the Global Warming Theory doesn't have cause and effect confused? Or is it a positive feedback cycle that is about to explode out of control?

We have barely scratched the earth's surface with our mines. Most mining operations go a few hundred metres at most into a crust many miles thick. It will be a long time before mining space is more viable than mining earth, no matter what figure you make up.

I have no idea where you get the impression that gold, platinum, lead, and other heavy elements can be found on Eros. Eros is an S-type asteroid [http://www.nineplanets.org/asteroids.html#astype% 5D, meaning its composition is mainly nickel-iron with iron and magnesium silicates mixed in. Nothing spectacular or special, quite pedestrian as floating rocks go - there are millions of them out there.

Also worth pointing out to you is what while Earth is not the largest body in the solar system, it is the largest rocky body known anywhere. Therefore it is unlikely that any other rocky body, from planet to floating pebble, will have a greater amount of any element than is found here, certainly not a 33 mile-long floating rock.

Also, none of the minerals you mention are currently uneconomical to mine on earth, the value of some them is rising not because they are running out, but because demand is rising.

Also worth pointing out here is that as Jupiter is a gas giant, it has no surface at all. There's little point discussing mining prospects on the surfaced of a planet that has no surface, but hey, maybe someone will buy a license from you.

Nope! Uranus was discovered by William Herschel.

Uranus was an early Greek God of the Sky, Son of Gaia. The word predates the english use of "Your Anus" by a couple thousand years.

Not quite what you asked for, but here's an asteroid with a moon

http://www.nineplanets.org/mimas.html

The surface of most moons is ice. Don't omit words when you refer to what I've said.

Damnit, now you're going to make me waste my time because you're too lazy to go do it yourself. So Be It.

Luna: Small areas of the poles

Phobos: A mixture of rock and ice. Since ice tends be on the surface and rock coreward. large areas of the surface, if not the entire surface, should be ice.

Deimos: Same as Phobos

Metis, Adrastea, Amalthea, and Thebe: Unknown. The low density suggests ice, but the orbit suggests a rubble pile.

Io: Little water ice. The average temperature is only 130K, but the surface is so active that it's hard for water to stay.

Europa: The entire surface is dirty or clean ice. This is even though it's a rocky moon with an iron core.

Ganymede: The surface is almost completely ice, but more diverse than Europa

Callisto: The entire moon is 40% ice, and 60% rock. Naturally, the ice is on the outside in a thick layer.

Leda, Himalia, Lysithea, Elara, Ananke, Carme, Pasiphae, Sinope, plus dozens of others: Unknown, but all have the density (as far as we can tell) of loose water ice, and theory says that they should be ice. Same with the outer irregular moons

Pan and Atlas: Shepherd moons of Saturn's rings - they should be composed of ring material, I.e., mostly clean ice.

Promethius and Pandora: Very porous icy bodies, as far as we can tell.

Epimethus: Little is known as we don't have a good density figure or spectral data, but given its orbit and its albedo, it should be ice. See also Janus

Mimas: Water ice, with only a small amount of rock. The surface is a mixture of clean and dirty ice.

Enceladus: The most pristine ice in the solar system. As far as we can tell, its surface is entirely clean ice in fine particles (like snow).

Tethys, Telesto, and Calypso: Tethys is clearly water ice almost all the way through; we don't have good data on Calypso and Telesto

Dione: Despite being the densest of Saturn's moons, it is still mostly water ice, with the typical shimmering icy surface.

Rhea: Quite similar to Dione; rock is less than 1/3 of its total mass, and its surface is shiny ice.

Titan: Forget about seas of methane; Huygens landed and showed a world of ice rocks, with the ice covered by organics in the lowlands. Oh, and it has an atmosphere, too, of a human-favorable density, which someone was stating that BSG people were looking for (for some bizarre reason).

Hyperion: Water ice with a little bit of rock near the center (noticing a trend here?). The only major difference is that Hyperion's surface seems to be coated with a thin layer of organics like Phoebe (more on that later), so it's not lustrous.

Iapetus: Almost completely water ice. Organics darken about half of the surface

Io: Little water ice. The average temperature is only 130K, but the surface is so active that it's hard for water to stay.

Europa: The entire surface is dirty or clean ice. This is even though it's a rocky moon with an iron core.

Ganymede: The surface is almost completely ice, but more diverse than Europa

Callisto: The entire moon is 40% ice, and 60% rock. Naturally, the ice is on the outside in a thick layer.

Leda, Himalia, Lysithea, Elara, Ananke, Carme, Pasiphae, Sinope, plus dozens of others: Unknown, but all have the density (as far as we can tell) of loose water ice, and theory says that they should be ice. Same with the outer irregular moons

Pan and Atlas: Shepherd moons of Saturn's rings - they should be composed of ring material, I.e., mostly clean ice.

Promethius and Pandora: Very porous icy bodies, as far as we can tell.

Epimethus: Little is known as we don't have a good density figure or spectral data, but given its orbit and its albedo, it should be ice. See also Janus

Mimas: Water ice, with only a small amount of rock. The surface is a mixture of clean and dirty ice.

Enceladus: The most pristine ice in the solar system. As far as we can tell, its surface is entirely clean ice in fine particles (like snow).

Tethys, Telesto, and Calypso: Tethys is clearly water ice almost all the way through; we don't have good data on Calypso and Telesto

Dione: Despite being the densest of Saturn's moons, it is still mostly water ice, with the typical shimmering icy surface.

Rhea: Quite similar to Dione; rock is less than 1/3 of its total mass, and its surface is shiny ice.

Titan: Forget about seas of methane; Huygens landed and showed a world of ice rocks, with the ice covered by organics in the lowlands. Oh, and it has an atmosphere, too, of a human-favorable density, which someone was stating that BSG people were looking for (for some bizarre reason).

Hyperion: Water ice with a little bit of rock near the center (noticing a trend here?). The only major difference is that Hyperion's surface seems to be coated with a thin layer of organics like Phoebe (more on that later), so it's not lustrous.

Iapetus: Almost completely water ice. Organics darken about half of the surface

The surface of most moons is ice. Don't omit words when you refer to what I've said.

Damnit, now you're going to make me waste my time because you're too lazy to go do it yourself. So Be It.

Promethius and Pandora: Very porous icy bodies, as far as we can tell.

Epimethus: Little is known as we don't have a good density figure or spectral data, but given its orbit and its albedo, it should be ice. See also Janus

Mimas: Water ice, with only a small amount of rock. The surface is a mixture of clean and dirty ice.

Enceladus: The most pristine ice in the solar system. As far as we can tell, its surface is entirely clean ice in fine particles (like snow).

Tethys, Telesto, and Calypso: Tethys is clearly water ice almost all the way through; we don't have good data on Calypso and Telesto

Dione: Despite being the densest of Saturn's moons, it is still mostly water ice, with the typical shimmering icy surface.

Rhea: Quite similar to Dione; rock is less than 1/3 of its total mass, and its surface is shiny ice.

Titan: Forget about seas of methane; Huygens landed and showed a world of ice rocks, with the ice covered by organics in the lowlands. Oh, and it has an atmosphere, too, of a human-favorable density, which someone was stating that BSG people were looking for (for some bizarre reason).

Hyperion: Water ice with a little bit of rock near the center (noticing a trend here?). The only major difference is that Hyperion's surface seems to be coated with a thin layer of organics like Phoebe (more on that later), so it's not lustrous.

Iapetus: Almost completely water ice. Organics darken about half of the surface

The surface of most moons is ice. Don't omit words when you refer to what I've said.

Damnit, now you're going to make me waste my time because you're too lazy to go do it yourself. So Be It.

Luna: Small areas of the poles

Phobos: A mixture of rock and ice. Since ice tends be on the surface and rock coreward. large areas of the surface, if not the entire surface, should be ice.

Deimos: Same as Phobos

Metis, Adrastea, Amalthea, and Thebe: Unknown. The low density suggests ice, but the orbit suggests a rubble pile.

Io: Little water ice. The average temperature is only 130K, but the surface is so active that it's hard for water to stay.

Europa: The entire surface is dirty or clean ice. This is even though it's a rocky moon with an iron core.

Ganymede: The surface is almost completely ice, but more diverse than Europa

Callisto: The entire moon is 40% ice, and 60% rock. Naturally, the ice is on the outside in a thick layer.

There are only about 5 particles/cm3 near the Earth, and it decreases from there by an inverse square law farther from the Sun. That's pretty darn hard of a vaccuum by common thinking. Yes, it will have a effect on a space probe going millions of miles, but calling it a hard vacuum isn't really that much of an overstatement.

Phobos' orbit is decaying and will likely crash into Mars or split into a ring within 50 million years

Io, moon of Jupiter, is smaller than Mars and has ongoing tectonic activity.

The energy for all this activity probably derives from tidal interactions between Io, Europa, Ganymede and Jupiter.
