What is your opinion on planets either in this galaxy or others far away dealing with life?

Short answer: very primitive life (algae, other forms of slime) are relatively common, perhaps 1 star in 100 has such life. More complex life (animals, plants, or the equivalent) much rarer, perhaps 1 star in 10,000 has such life. Intelligent life, which we can define as an entity capable of building something like Yahoo Answers, is likely very rare. Perhaps 1 star in 1,000,000 or even less. We may be the only intelligent form in our Galaxy right now.

No way, there must be many, many planets throughout the universe that are similar to our own and support life. There are probably many others that support life that is much different than we are accustomed to also.

Life on other planets\nMeanings of the things\nLife\nEverything\nNothing\nGod\nDemons\n\nAnd so on…\n\nThe most important may be the exact answer for your question ;-)

I doubt that Earth is the only planet in the whole Universe that can sustain life.  There will probably be some other planets out there somewhere with some sort of life on it.  Whether it's intelligent life or not is another question!\n\nThere may very well have been life on Mars, or on other planets in our solar system at one point,  but we have yet to find it, or any evidence.

Yes, we will discover other planets that also sustain life, and we will do so within our lifetime.  I do not mean that we will physically go to these planets but we will discover this by placing much more powerful telescopes in orbit around Earth.  There is a definite signature that we will be looking for and that will be the presence of Oxygen in another planet's atmosphere.  If a planet does not have any oxygen in its atmosphere then it would not be able to support life.  There was a time billions of years ago on Earth when there was no oxygen in the atmosphere and at that time there was no life on Earth.  We may not discover other intelligent life on other planet's during our lifetime but i am sure that we will discover other planets that are supporting at least plant life if not primordial single cell life as well.

Absolutely! The odds that they exist are overwhelming when you think of how GALAXIES are scattered like specks of dust!\nNow... even though aliens exist, what are the odds that they are on another planet in our galaxy right NOW? Think about it... It took 50 million years for humans to appear on Earth. How long will we be here?... only 50 to 100 thousand years (hopefully)? How many other planets will bring forth intelligent life - not a whole heck of a lot. And of them, when will that life be around? Just a tiny amount of relative time.\n...What I am saying is that EVEN IF other civilizations were, are, or will be... the timeline of the universe is too insanely long for any of us to be co-existing. The reality may very well be that we are currently very alone here in our time and place. I hope this gives you a new, more realistic way of seeing things. Sorry it's such a downer, though!

I would love to visit a planet orbiting a star that has strayed away from the plane of our galaxy. Imagine the night sky lit up by an entire galaxy - a great luminous spiral looming overhead.\n\nThe Valles Marineris must be quite magnificent too. It is largest known canyon in our solar system. Like Grand Canron, much more vast and red.

There are too many other planets in the universe to say that ours is the only one with intelligent life on it! That's human arrogance to say this one planet is the only one with intelligent life. Since we haven't meet any,then their aren't any! Is what most people believe,but I think their is! Everyday we are finding new forms of life right here on our own earth that we didn't now was here,til we found it. Space is so vast, the universe is endless and other species from other worlds probably face the same challenges that we do in space exploration. They haven't discovered how to travel through space and such great distants just as we haven't. Or have they? Remember The Thing! Who knows what could be frozen under the Artic and how long it's been there! Also, I believe that their are species much stronger than us, with the power to inslave us or put us on the food chain. I know this is far out,but think about it...we as humans eat every other animal on the planet cause were the strongest! Now if a stronger species than man took over the earth,who knows man could be on the menu!!!

Proof, so far there is none, however if you take into account that there are trillions of galaxies each with trillions of stars all of which may potentially have planets, then you have to consider that there is a good chance that there is at least one other planet out there with the potential for life.

Is there such a thing as close by planets?\nWith all that we see in the night sky, not just stars but galaxies as well, what are the chances that we are alone in the universe?\nThere has to be intelligent life out there. We are all just too far from reach of each other. And most likely, other intelligence would be like us and send probes. Living beings could not survive the long travel, space probes could.

Since there is no planet UMO in our solar system, I assume you are referring to a planet outside of our solar system.  \n\nScientists have discovered extrasolar planets,[1] but all of the planets we discovered are so far away, that even if we had sent a electronic signal to them the day we discovered one, since such signals move at the speed of light, our signal to them would not yet have arrived.[2]  Therefore, regardless of the name of the planets we have discovered, the limits imposed by the finite speed of light preclude the possibility of any ongoing communication with the planets (or more precisely, with any possible intelligent life that might inhabit them).\n\nIn short, no, there isn't.

Definitely.  Even if its just some microbes out in space, just the sheer number of planets and stars etc I would think there would have to be other life out there!

A recent scientific study estimates that there are AT LEAST 70-sextillion stars in the universe, one of which is of course are own sun. The odds AGAINST none of those other stars having planets occupied by sentient life are astronomical (pun intended). Undoubtedly of all the life forms that exist in the universe some are technologically at the same level as we are, while others are at least several thousand years ahead of us. Still others might be where we were 3-million years ago---just down from the trees. Certainly, any alien life with any intelligence at all must wonder if there are other life forms somewhere other than their own world.

My gut agrees with you, but I wouldn't jump to any conclusions. A sobering (and excellent) read is Rare Earth by Ward and Brownlee. One is an astronomer, the other a geologist. They make a convincing case that sentient life elsewhere in the universe is probably quite rare. At a minimum, they make minced meat out of the Drake Equation. Still, with so many possibilities ...\n\nThe other thing to remember is that first and possibly second generation of post-Big Bang stars could never have supported planets with life of any kind. It took billions of years before stars produced sufficient quantities of heavy elements that are essential for life.\n\nand, all those stars and all those galaxies don't exist simultaneously. As we look farther out into space, we are more and more likely looking at objects that no longer exist.\n\nso, having said all that, we must consider this. a) sentient beings are probably quite rare - whether you accept Ward and Brownlee's extreme argument or not. b) that life could only have existed for, say, the last 8 or 9 billion years of the universe's existence. c) the distances to other stars in our galaxy are vast, but the distances *between* the galaxies are mind boggling vast (there's a reason that even in Star Trek, with it's fantasy warp drive, the story lines are all confined to our own galaxy).\n\nJust food for thought.

Out of 10,000 Billion Galaxies out there. No Doubt there is something out there.\n\nEarth will contact something...but not in our lifetimes.\nI even believe there is another planet like ours out there somewhere.\n\nWe would be very naive to think we are the only intelligent planet in the entire Universe.

I am almost 100% certain that life DOES exist on other planets, and may be in completely unfathomable ways, that we could not begin tio understand.\n\nIt us very interesting that the prospects of life having once existed on Mars are become more likely, due to the significant discovery that water once was in abundance there.\n\nThe trouble with finding life in other solar systems is that the distances are just too great. Even radio waves take 4 years to reach the nearest star from the Sun, then you need 4 years for the reply. The majority of stars are MILLIONS of light years away. so EVEN if there are a Billion planets with intelligent life there is no way of being in contact.\n\nBUT I do hope I will find out that DEFINITE life has been proved to exist before I die.\n\nI find this a fascinating subject.

I believe there is life other than on Earth. Even if just mathematically!\nAn interesting point though, is that the authorities on this field have concluded that the nearest system that COULD support life is Sirius. That's interesting, because throughout history, the more believable tales of alien contact seem to all point to that star system. The Dogon tribe are a classic example of that. They apparently knew of Sirius A and its two companions(Sirius B and Sirius C) long before any 'civilised' society. Sirius C has yet to be discovered, but could well be there! I quote from Wikipedia: "Apparent orbital irregularities in Sirius B have been observed since 1894, suggesting a third very small companion star, but this has never been definitely confirmed." \n\nAs to us being Parasites on this Living Planet, I couldn't agree more.
