Science is reinventing play, from extreme sports to gamification to ridiculous roller coasters to the playgrounds of tomorrow, and this issue is chock full of fun. Also, on a less fun note: Did global warming destroy my hometown?
But according to the prop the planet must be earth-like. In reading the article, the planet, HD 189733b, has the mass of Jupiter and an average temperature of 1,700 degrees farenheit.

then how does it have water? exactly. puressure?
oh and is there a ppx prop for the boeing laser cannon?
billcosby is right about this planet not being earth-like enough to satisfy the prop. However, as we've seen in the past, as soon as they've identified a way to find a planet with something (in this case water), they find a whole slew of them shortly thereafter. I therefore believe that the planet that will satisfy the prop will be coming along soon.

I don't think we'll find any life. 2010 is scheduled to be the end of the shuttle and the start of the new exploration plan Bush proposed. Also, the ISS is supposed to be finished that year, marking the year that the most expensive object in the history of mankind will finally be finished.
Life isn't a requirement for the prop, just an earth-like planet, so water, atmosphere, land, 1G-ish gravity, etc.

Either way...basically, it would have to support terrestrial life, and if none was already there, then it would only take time.

Anyway, exoplanets are billions light year from us, so when we look at them with the telescope, we see them billion years ago, if we find one with water, well in real time, planet has time to explode by the time we will get there imao.
Well, most of the exoplanets found so far have been in the 200 lightyear range (give or take), but you're right. The image we see left that solar system approx. 200 years ago and is not what the planet looks like this minute (talk about God's time machine). An astoroid could have collided with the planet 100 years ago and sent it into a nuclear winter but we wont know that for another hundred years. However that wont affect the prop. Matthew, I disagree with your comment that "if none (terrestrial life) was already there, then it would only take time." We haven't found life anywhere else but Earth and we still aern't sure how it happened here, so to assume that just because a planet is earhtlike, it will sprout life, is a long reach in my opinion.

I agree also, what I meant to say was, if none was there, then, if conditions are earth-like, life has a great possibility of being there.
or traveling there from here ;)
thats the one thing thats goin to suck even if we find a planet that can support human life. So if wedo happen to find a planet that can support life[very very likely], we wont be able to get there. At least not anytime soon.
Put on your thinking caps, and starting thinking about how we are to get there too. Otherwise, its worthless!

theres always terraforming, find a similar planet and just change it. Mars for example with some more atmosphere it could be livable
How would you give Mars more atmosphere? Also consider that the magnetic field on Mars is almost non-existent, so there would be almost no protection from cosmic rays and other radiation spewed by the sun.
Once again, a mysterious change in a prop's direction that goes COMPLETLEY counter to the latest news...
EARTHLK drops 3.00 today on the news that NASA will be launching a space telescope specifically designed to search for earhtlike planets. The telescope will continuously monitor 100,000 stars for evidence of earthlike planets.
Check it out at http://www.floridatoday.com/content/blogs/space/2008/11/rocket-raised- for-nasa-planet-hunt.shtml (clear out the space between raised- and for- in the link...)
Since over 200 planets have already been found circling other stars using largely earth-based technology, this is a giant leap forward.
And it's due for launch in the spring, meaning that the search for an earthlike planet with water will have a new and incredibly powerful tool... with most of a year to explore before this prop hits its due date.
AAAANNNNDDDDD... we need to be clear about what "Earthlike" means. In reviewing several articles on the subject (links below)no one seems to have a hard-and-fast description, but the clearest distinction is that terrestrial planets are composed of rock, rather than gases like Jupiter and Saturn.
This is why they refer to rocky planets 8 times the size of earth as "earthlike". They may be huge, but their composition is similar.
Given this definition, they do not have to detect water on a planet our size, but rather can detect it on a rocky planet of much larger dimensions.

By no means is this to say the discovery of an earthlike planet with water is going to happen any day now. But it might happen. And if I'm going to be holding this stock, I'd much rather be holding it long until its a lot closer to the end date.
To the inevitable comments that the stock's fall was because "It Wuz Wave Riding", I'd like to point out that waves only happen AFTER the stock has started moving. This one's movement might have been coincidence... or it might have been the result of the short-sighted lemmings who said "my god, that telescope won't be up there until spring!" Anyone who thought that way really didn't think very far or very clearly.
