Cool article, thanks subby!

So if 55 Cancri-e is full of diamonds doesn't that mean that if we mine it the price of diamonds would plummet, such that the planet is not really worth $27 nonillion dollars?

Keep in mind, it would take $28 nonillion dollars to mine it and bring home the payload. But... JEWEL BATH!

TFA: "HD 149026b is located roughly 256 light years from Earth and is slightly smaller than Saturn. The planet is so hot, it shouldn't even exist. If you were to look at HD 149026b in infrared, it would shine like a star - thousands of times brighter than Venus (the hottest planet in our solar system). Astronomers have calculated its temperature to be roughly 3700 Fahrenheit which is just above the predicted limit. It's impossible for a planet to get this hot. So how did "planet hell" get so hot? Only an absolutely black planet could absorb enough light from its star to reach this temperature."

The fact that we have arrived a the point where we are categorizing exoplanets by the dozens MOOII style is very exciting.

Well, you'd have to get there, mine it, and get it back here... On top of tat DeBeers has some kind of farked up stranglehold on the market, so they'd probably just sit on piles of money and count them... Seriously, my budy was working for whatever mining company owned the diamond mine found under the lake in Canada(I think it was BHP at the time), and He said that there was some weird grace period where diamonds had to be sold thru DeBeers before they could sell independently, so it was easier just to sell the mine to them. I can't remember the exact specifics, but it was all farked up. I'd guess they'd do the same kind of crap if we found an entire planet made of diamond that we could actually get to. Those bastards suck.

Pretty good find, subby...

Although I can't belileve anyone would need to know why we're looking or why they'd be hard to find. I guess those wold be the same people who can't understand why we can't spot a 100 foot asteroid coming towards the Earth.

"Strange" is all relative.

What if a Nitrogen/Oxygen atmosphere with oceans of liquid water turns out to be "strange" when compared to the rest of the galaxy?

Having inhabitants made out of "meat", that is.

But then again, discovering an exoplanet made out of meat sounds tasty and could solve the hunger problem.

According to the IAU definition these are not planets.

Personally, I'd rather go to some of the gold and diamond asteroids in the belt between Mars and Jupiter than to a planet in another solar system.  Get back to me on this matter when FTL travel is an option.

Tin Foil Hat On:  My personal conspiracy theory is big businesses & governments are against space travel & colonization because of all the natural resources that can be acquired away from Earth which, depending on what's found and how easy it is to transport back here, could completely destroy certain markets like gold, which all currency is based on.  :Tin Foil Hat Off

Once you got out there, getting the stuff back wouldn't be hard at all... Really just drop it into the atmosphere in the right window, and let it fall to earth. It's getting people and supplies up there. Of course, that's why I'm in favor of a base on the moon or a space station. We can make our spaceships differently if we don't have to fight gravity and atmosphere like we do to escape Earth. I don't think it's a conspiracy yet, I think it's tough. At least we seem to finally be finding water sources, which I think is the toughest resource to get up there.

It won't get any cheaper to go out and mine the asteroids until the ships are operating from the moon. You'd have mining ships going between the moon and asteroids and support ships between Earth and Moon. Making a stop at the moon on the way to the asteroids is a waste of energy. It still won't get cheaper until most of the supplies are already at the moon and the ships can be manufactured at the moon. But, there's no conspiracy. Simply going to space, even if you don't do anything once you get there, is very expensive.

Thanks KS for not reading what I posted, but responding anyway. I would have typed with fat more detail if I'd know that you were joining the party.

Yes, we have to base our ships for space from somewhere other than the Earth because we use most of our fuel escaping the Earth's gravity and atmosphere. And yes, we will be able to make lighter, more efficient ships when they don't have to land on he earth anywhere.

Landing isn't the problem, it is getting off the ground again. If we base our ships somewhere other than earth, we can conserve fuel and make the mining ships lighter and more efficient.

Just build a space elevator already! The mass coming back down to earth can lift the stuff that needs to leave the planet.

Would have replied yesterday but the ass end of the day was busy.

I agree with that, and those have always been a problem, the gravity and water, but with current weather trends, the destructive mining techniques we use, and our reliance on finite resources, including things like helium and hydrogen, we have to find new sources for resources and those sources are in space.  I've always been in favor of a moon base, especially if it has a theme park, and with possible water on the poles, it's as good place to start our species' journey into the unknown.

Yesterday I read an article about how the Navy is working on turning seawater into electricity and jet fuel.  The only problem with that is instead of burning oil for fuel, we're converting water which is literally the planet's blood and life force, and while it's plentiful now, just imagine the problems in a hundred years when tens of thousands of ships are extracting seawater for fuel.  Yes, some exhaust will be water and water vapor, but more is lost than what will be replenished.

Point is, either we keep screwing the planet more and more or we nutt up (vag out? what do chicks call it?), do what needs to be done, and become a space traveling species.  There will be difficulties, high costs, and many deaths along the way, but the possible survival of humans is worth those costs.  With what we know of theenvironmental damage we're doing and have done as well as the potential for Earth itself to cause massextension on a global level, it's just damn stupid to not start on these problems now rather than later.  Right now we're a like a rich guy in California with a big mansion in the mountains, eventually a fire will come and burn it down (bad global event hits planet) -- if he has a second house (space base/colonies) in case that happens he'll be fine, if not, screwed....don't bring up home owners'  insurance, assholes, because we don't have access to Gleep & Glorp'sPlanetary Insuracne Co.

My tin foil hat theory is more about the economics of space travel and how once resources are found and transportation routes established certain things like gold could possibly lose all value because it won't be "rare" anymore; if gold we're to suddenly lose value who knows what would happen to the world economy.  It isn't about the limitations of getting there.  We, as a species, know them and know that the only way to lessen those limitations is to actually do it and develop better tech along the way (or figure out gravity....).

The benefit of a moon operation is that it doesn't have much of an ecosystem to pollute, and no atmosphere to speak of. If they plan from the beginning to utilize all the waste that is possible, and launch truly toxic stuff into a decaying orbit around the Sun, we could really make a moon base work as a station to base our early space work from. We could utilize the moon's resources, but avoid the messes we've made on the Earth. We're never going to be able to pollute the Sun, I don't think...

Yeah, this was my thought on the sea water story. It's cool and all, and it will be a more environmentally clean exhaust, but that shiat comes from somewhere...

I just think about that SG1 episode where the dicked with the dialing protocols and dropped off uranium??? into a star they gated through causing it to red shift and screw the planet they went to.  Because of that I wonder if we dump the wrong thing into the Sun if we won't screw ourselves in a similar manner.....but that's what the gas giants are for :p

Moon, space colonies, and resource satellites like in Mobile Suit Gundam is where we need to be heading.  Other than the giant, fighting, mechs, it has always bothered me how accurate MSG is for the reasons humans went to space and how we're discussing the same things for the same reasons now, or at least I am -- survival of the Earth and us brought on by pollution from greed and war (we're not there yet, but we've been damn close at times).

Dammit, now I want to rewatch a lot of crap.

/I really miss Stargate
//There needs to be a new series
///I've thought using the Atlantis warp drive to get to the Destiny, the ship in SG: Universe, would be a decent starting point.  Or Stargate Command (pretty obvious what that's about)

The absolute amount of material we would have to drop into our Sun at once is mind boggling. I even wonder if something the size of our moon would do much. The Sun is so silly large, I think it could eat an aircraft carrier full of anything, and maybe do nothing more than burp politely.

Lol.  Besides that, most crap would probably be burnt into vapors long before it actually get there.

We could just send crap to a space between Jupiter and Saturn, let is mass up, and have a garbage world, or just, you know, improve recycling and manufacturing technologies.  The problem with that is when something is made well you don't need to go to WalMart and get a new one a few weeks later, but, in the end, that's more of a capitalism/political thing we don't need to go into.
