Scientists Find Water on Extra-solar Planet 220
amigoro writes "Scientists have, for the first time, conclusively discovered the presence of water vapour in the atmosphere of a planet beyond our Solar System, according to an article appearing in Nature. They made the discovery by analysing the transit of the gas giant HD 189733b across its star, in the Infrared using data from NASA's Spitzer Space Telescope. HD 189733b is a 'hot jupiter', a gas giant that is roughly the size and mass of Jupiter but orbits very close to the star, so no chance of life there."

This is a pretty bold statement. Scientist predicted that life couldn't survive in a number of environments on earth, yet it has been found in each one:
1- In lakes frozen hundreds of meters down in antarctica
2- In the dept of the ocean where NO light permeates
3- Next to Volcanic openings in the earths crust were tempuratues are well over 800 degress c
4- In the highly acidic and poisionus ponds in Yellowstone National Park
I am sure that there are more but I can't think of any.
So for some scientist to say that there can't be life, I just have to role my eyes. One thing that I have learned about life is that life will find away. So just because we can't concieve of the possible forms that life might take its a little presumputous for us to assume that it can't exist.
Earth is a small speck in the universe, it doesn't matter if you believe in God or not but to assume that life, as we know it on this planet, is the only form and location of life in the universe is a very ignorant view point.
I am of the firm conviction that as soon as we have the technology to explores these remote and hostile locations we will find things that we haven't even dreamed could exist.
So to get off my little soapbox here; if there is water there is probably life, and just because the conditions on the planet don't fit are current formula for life doesn't mean that our formula is correct.

yeah, what do they know. I mean after all, some scientists in the past have made predictions that were wrong, so you'd be a fool to listen to anything a scientist has to say.

It could very well be that the "arrogant" or offensive answer is the right one. The total lack of any evidence for extraterrestrial life, intelligent or otherwise, should be a strong indicator that we are very, very alone.

Mars, we've not even gone to. We've got some rock inspecting toys up there, but that's about it.
Venus, we've never been to there either. Our probes have sampled the atmosphere, that's about it. We still have no idea why it has such a strange rotation.
We have absolutely no credible statement to make about the prevalence of life in the solar system, let alone the universe. But hey, anonymous person on Slashdot, thanks setting us straight.

According to this theory, it would be impossible for a gas giant to form so close to a parent star, it would be blown to pieces. So clearly one theory or the other is wrong here. Since I don't hear a lot of other scientists laughing at the extra-solar planet people, I'm guessing the original planet formation theory is wrong. So, what's current?
Flawed Proposition (Score:4, Insightful)
The universe is largely transparent, and we can see almost all the way to its privates. The decorations are of the same style and motif throughout, so we can pit our local gravity-well spirlies against theirs and make some reasonable guesses about how far away far is. Since it turns out it's in the neighbourhood of 13 billion lightyears away, I think we can -- as civilized folk -- agree that 13 billion is more than a golybillion shy of infinity.
Check my maths if you're a stickler, but I'm pretty sure I'm on solid ground here.
Space is finite (if gummy), therefore the number of decorations whorled up by our familiar physics is finite, therefore the number of little planety lumps inside of them is finite. Q.E.D.

We know the human race is not special from a biological POV. For me, that is the limit where arrogance stops. I have a hard time thinking about arrogance in favor of a type of lifeform (nationalism, racism, specism, lifetypism?).

I believe that statement is incorrect. Intelligence has a finite limit when it diverges to stupidity. However you can't define an upper limit of Intelligence.
Intelligence starts off from 0 and shoots off into infinity.
Therefore in an infinite universe, you are always stupider than the rest of the Universe.

Jupiter cleared its orbit when the solar system was young, mostly by flinging other objects out of the solar system. In doing so, its orbit shrank. Given a denser environment, the shrinkage appears to be able to continue until a gas giant gets quite close to the parent star.
