I am so fascinated with Astronomy. This is an amazing story.

Thanks for the link! That is great reading material!arnisador said:I read that. It certainly is encouraging--so many of the others have been gas giants.
Some nice lists of extrasolar planet extremes here.

it is pretty cool stuff, eh? glad to see that others enjoy this kind of news. this is the important stuff. not the other **** you see on CNN and FoxNews.

Yes it is! I have been following the rovers' stories from the time they launched until now. It is absolutely amazing the images that were sent back from Mars. I couldn't tell you how many times I looked at those pictures, zooming in and checking out the rocks. I am very hopeful they will find evidence that life existed and may in fact still exist on Mars.upnorthkyosa said:The fascinating thing about this article is the impact that it has on the field of astrobiology. In our solar system, we already have a number of celestial bodies that qualify as candidates for extraterestrail life. We are only (literally) a step away from discovering life on Mars!
This is profound.
I am convinced there is life out there somewhere. We have only scratched the surface in space exploration. If life exists here, it MUST exist elsewhere. We cannot possibly be alone.upnorthkyosa said:If life is so common in our solar system, then it is reasonable to assume that life is common in other solar systems. Further, according to the article, small rocky worlds are far more common then scientists once thought. Putting these together, we literally could have a galaxy (a universe) that is teeming with life.
VERY thought provoking! That is very interesting perspective. Thanks!upnorthkyosa said:If this is the case, one has to ask, why hasn't the Earth had clear and unrecognizable proof that intelligent extraterrestrial life exists?
I think the answer lies in our solar system's place in the galaxy. We are located a long distance out on one of the spiral arms and there are very few stars that are near to us. In fact, one of the reasons the sky is predominated by black is because we are so isolated. (If we were closer to other stars, there would be more photons zinging around to brighten things up at night a bit)
I tend to think of the Earth as the Easter Island of the Milky Way. We are way out in the sea, cut off from all extrasolar influences. Only the most advance transportation systems or a rash and desperate act could get out this far to find us. Our First Contact could come in a million years and they might just find a bunch of toppled monuments amidst an island that was laid to waste...

Yes, true! That reminds me, they recently discovered a system that has 3 suns. This topples many theories about how systems are formed. Basically the planets have 3 suns. It defies much of what Scientists knew (or thought they knew) about gravity and formation of planets. LOLGemini said:So much theory, so little fact, yet always projected as fact. Just like the most recent theory I heard that a black hole now must exist at the center of every galaxy and is in fact, the core of what every galaxy is centered around. I'm not saying that many of the theories are not well founded, but why can't they ever just start a sentence with "We believe"? It's always presented as fact. Right up until they disprove one of their theories, which they have on many occasions.
Besides the human species, just imagine what will happen to the foundations of religion. :O I too am disappointed that I probably won't be around to see it. What an amazing time that will be!Lisa said:I so totally agree! Life has to exist somewhere else as well, we just can't possibly be the only ones out here. What saddens me is I probably won't live to see it discovered. I think it will really shake up the human race when it happens.

True! more like we have just scratched the surface of the porch LOL Well maybe a small scuff mark.bignick said:That is actually an overstatement, we haven't even left our porch yet...once we step onto the front lawn, then we can start talking about actually exploring.
Likewise, there is no basis for the arguement that there is no life. To prove either one, we have to know far more than we do. I tend to be an optimist. Truthfully, there are no hard facts, the basis is pure numbers of probability and the fact that the elements that created life exists here, they certainly can exist elsewhere. Think about the massive universe and all the galaxies that exist there and how many yet to be discovered. It is highly improbable that our TINY planet is the only one that has formed that can and does support life.bignick said:I don't really think there's any basis for this argument, however. There's no reason life has to exist elsewhere. Minus religion, there's no reason we should exist either.
