Life? Umm, there surely is on Mars...some bacteria, fungus maybe...and yeah, a bunch of interesting viruses, I guess. I'm skeptical that there's any type of what we call life (multicellular organisms with an advanced degree of structural development) anywhere close to us. NASA and other agencies all over the world have been studying for 'alien' life forms for more than half a century, yet they only came up with 'habitable' planets, but there's no sign there might be life on any of them.

When you realise how big the universe is, you realise how probable it is there is life somewhere else. It would be cool to make contact with an alien species and have a chat.

Although, they might not communicate using the same senses as us. Imagine that, they use all that effort to get here, but have no method of communication. Makes you wonder.

There are some questions which can't be answered, as people from SETI build those antennas to detect some waves from other beings. We have to just wait.
But I think there might creatures in other planet who don't need water, air at all.
We can't be sure of anything. If someday they visit us, they may be surprised that we need water and oxygen as bare essential for life.
And this topic would never going to end...

We shouldn't try to make first contact! We should develop our own technologies so that atleast we are on par with maybe asgard (from stargate). Because there is without a doubt that many 'aliens' out there are not going to be friendly. Trying to make first contact is inviting a technologically superior species to Earth, and what if they react violently? We'd be helpless... and remember the saying -curiosity killed the four legged feline (cat).

Also, the moon Europa orbiting Jupiter has an ice surface, considering what Jupiter can do to Io then underneath the surface of Europa must be vast oceans teeming with life.

Life doesn't need sunlight, as long as it has warmth, moisture, and nutrients it will survive.

Considering how many solar systems that area out there (googols, maybe even googolplexes) of 'em. About atleast 3/4? will be blue supergiants with super gas giants orbiting it etc etc. Others will have super gas giants orbiting suns and during summer (on that planet) half of it goes inside the star itself.
Others will have a look similar to our solar system but that number will be miniscule.

And last of all, the pictures of stars we are seeing are actually millions and billions of year old, some stars would have even being destroyed and moved. So a star presumed to be '10 million years old' and is '10 billion light years away' but in real-time the star is already 10 bil+10mil years old...

Just considering how vast the universe is, there must be live. There could even be life on the ice surface of Europa...

Okay, I'm just going to go through one of my many theories on the subject.

Yes
I fully believe that there is life elsewhere in the universe.
As I'm sure was mentioned many times in this thread, if you take in the sheer size of the universe, and take in the massive, massive amounts of rock bodies and planets, all with slightly different compositions... There has to be life on other planets.

Didn't scientists find a planet last year or the year before that they thought had an atmosphere similar to Earth's, or they thought humans might be able to survive in?
I mean, that has nothing to do with my theory, but if my memory serves me correctly, that there proves that Earth isn't all that unique. And neither is life.

However, I try my hardest not to share the same arrogance that most of the human race does when they theorize on this subject.
And I apologize for the use of the word arrogance, but it's what I see it as. I don't see this as a negative use of the term though.
I don't see why, if there is other life in the universe, that it would be civilized in any way such as humans.

Think about it
There are thousands, maybe millions, of different kinds of life on Earth alone... And only one species managed to civilize themselves, and managed to make the (what has to be) one in a million chance pass over into starting to evolve into discovering things like technology.

While I wouldn't be surprised if there were species on other planets that, say, had technology similar to prehistoric man, or even with a language. I just don't see it likely that there are other life forms in the universe hanging out behind the computer.

I don't see any reason why an alternate life form, billions of light years away, would follow the same path in evolution that humans have found.

---

On a slightly more pessimistic note:
If there are other life forms out there, I don't think it will ever be revealed to us.

As much as I hate to put limits on possibilities,
traveling at a speed above the speed of light doesn't seem much like a possibility. None the less, several million times the speed of light.
Which is what would be required to travel to one of these distant stars, that are billions of light years away, in any amount of time comparable to the human life span.

So something tells me our universe is going to end up like North America and Europe before the 13th century (14th? 15th? Whenever Columbus sailed his *bottom* over and said "hey, there's inhabited land here").
There's life out there, life living,
But we just won't know about it.

And just to add to the first part of my post, because I realized something as I made the Columbus analogy,
When Columbus did, indeed, sail across to North America, it was revealed that Europe and Asia's technology was vastly superior to that of the "New World"'s people. In fact, I'm near positive that European explorers referred to the First Nations people as 'Primitives' or 'Savages'.
Finding life on other planets would probably be moderately similar to this.
It could be there,
And it could be living perfectly adequately for itself,
But it won't be living like us.

Even though our universe is very large, that does not say that it needs to be life somewhere else. Maybe, or maybe not. "Of course there is life" is wrong too say. Nothing is sure, so we can't say it is right or wrong. Personally I do not think there is - I think that even though it is a large universe, we are the only planet where it currently is life. But maybe there where life somewhere else, before humans came to this earth?

Well you could say their is a misconception about Life in the universe, or rather the answer itself. Is there other life in the universe? Yes and No. When it comes to species like human then the answer is no or rather unknown at this time, and the same could be applied to the rest of the life on Earth that has some sort of intelligence, communication, and survival. Now at the atomic, bactieria, and other microscoptic life levels the answer is yes because those are forms of life and in a way are the building blocks of life as well; however, since our technology is so limited and the universe is so vast that it could take millions or even billions of years to find anything remotely close to what Earth has. Of course the odds are low that we could receive a signal from some part of the universe, but you run into one problem that signal could be millions of years old, and by the time we get they could be long dead. Who knows though but of course I wouldn't worry to much about life else were and rather rather worry about life here, just because its more of a priority then anything else.

As far as life on other planets is concern, I believe it exist. As well as science supports the fact.Along with this Religious scriptures gives indications as well. And as we know we have seen some UFO evidences on earth too.Thats enough to believe the theory.

Can anybody tell me about is it possible ever to go to other planet's having life? i mean if some one knows latest data of NASA or something?

Of course it is! There are many different ways. But i doubt NASA will have the funds to do it. By the time where we could travel to space just as simple as going to a nearby amusement park, then we would have ships completely made of carbon nanotube fibres and titanium-carbon nanotube interweave as the hull.

Let us just hope that by that time, we have perfected the process of reviving people from suspended animation and that we can achieve the temperature of absolute zero. Let us also hope that we have achieved much higher propulsion efficiency.

But by then I doubt there will be a 'NASA' by then there should be a giant multi-national agency.
