In a few years we will be able to take readings of the atmospheres of exoplanets. That´s about it. But we could still be able to detect life on such a planet by studying it´s atmosphere. Molecular oxygen can´t be explained in another way.

With the nearly infinite number of stars out there, it is reasonable to expect that life has developed on another planet. However, we won't know for sure until we actually encounter that lifeform, and that may be a long way off.

it's a hard question to answer, cuz same as you can't be certain aliens don't exist, you really can't know for sure if they do !! Although I can't say they exist ... i don't really see it impossible ... they "might" exist ;)

Can I recommend you to explore http://www.seti.org/ - site for Center for Search for Extraterrestrial Intelligence (SETI). The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.\n\nHere you will get meaningful and scientific explanation to UFO/aliens.

yes we can, and actually astronomers have been working on it for the last 15 years or so, the problem is that there is no telescope currently powerful enough to directly see any planets orbiting other stars, the most common problem is that what little light is reflected by the planet gets easily lost in the glare of the stares light, so the only way that we can find out weather or not a star has planets orbiting around it, is by looking at the influence the planet has on the star, like causing it to wobble, this is because as a planet orbits around a star, it causes the star to slightly wobble with the orbit of the planet, and it is that slight wobble by which astronomers can estimate the mass and speed of rotation and many other details about the planet.\n\nnow if you are asking this to find out if there's any life out there, i would suggest reading this book called "Faint Echoes, Distant Stars" it will open up a whole new world of possibilities to you, here is a link to it\nhttp://search.barnesandnoble.com/booksearch/isbnInquiry.asp?z=y&isbn=0060750995&itm=4

No.\n\nSo far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.\n\nWhy haven't we heard from them?\n\nPerhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.\n\nPerhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that flew by may be a surveillance craft.\n\nPerhaps they are so far away they will never notice us and vice versa.\n\nPerhaps they existed a million years ago and died out.\n\nPerhaps they will exist a million years from now.\n\nIt is really impossible to know for sure.\n\nThe Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

yes.  Here is a post of mine with the info on it about life outside our planet, maybe even in our solar system.  Be aware:  Most planets we found are "hot jupiturs", which are jupitur sized gas giants with temperatutres about 1300F at average.  \n\nThere is a possibility.\n\nI have done PLENTY of research in astronomy. I just am so into it. Anyway, I beleive yes, and my reasons:\n\nEarth itself seems perfect. Perfect climate, actaul liquid water, etc. But did you know animals (and I mean animals, not bacteria) could adapt over time to certain places? For instance, In Jupitur, there might be life. The appearence: Most planets are gas giants, and they need to be able to withstand a good amount of temperature (We are alomst guarenteed the only solar system with rocky planets and temperatures colder than 1300F on average). This would be the perfect place for, as the books described as, Floaters And Swordtails. Floaters kinda would be blimps. They would be organisms flying in the perfect temperature zone and flying with the baloons on their back. However, a sword tail would come. Using its super wings, it can fly lightning fast. Its sharp beak lets it tear right through the floater for food.\n\nOn EUropa:\nOn jupiturs smallest of the Gallelaio moons, there is a greater chance of having life than mars. The reason: Ice flows cover the surface. The ice flow tend to crack, bu recover. The process is also found on earth, and is now beleived that liquid water lies under the flow.\n\nThe appearance of life:\nSkating on the ice on Europa, An unnamed organism skates around, using its green body to undergo photosynthesis to produce food. Because It needs no air and makes food like plants, they need no mouths.\n\nVenus (What most planets moons probibly look like):\nOn a hot planet like venus, you need to survive insane temperatures. Eating rocks would also be good, for the fact that its mostly the only thing on the planet. Oh, and leave out the need for water. They cant get any there. \n\nThe appearence: \nStanding on the scraps of a russian probe, an oucher-poucher stands on 1 foot to avoid the insane heat, eating the scraps of the ship. The oucher pouncher needs no water, so it doesnt need hydration. Its body is also meant to withstand any type of pressure, for 90x earths pressure would surely crush it normally. \n\nPluto:\nPluto is made up of all types of ice. water, dry, though mainly methane. So drinking, again, is out of the picture. They might beable you suck moisture though. The sun is to far away for solar energy, so you can slash out all photosynthesis.\nThe appearence:\nPlutonian zittsles are almost small ice chunks with legs. They are able to last in temperatures in the climates back in the far end of the solar system. In the morning, they do whatever they can to stay cold, for they feel that -234C is almost the exact same as 103F for us. At night, they really get going. They send waves to eachother to communicate while the atmosphere is still up. When they really are energetic, they can spring in the air up to 30 feet. They use tiny mouths under them to suck moisture from the ice. They think that pluto is the only place for life; Everywhere else is to hot. \n\nTitan:\nTitan is the only moon that we know of that can support life. Its atmosphere is composed of mainly nitrogen, similar to ours. So it does have a green house effect. The ground is covered with ice, so they have to eat that for water. Also, they would need to keep warm, since although its not extremem temperatures, its really cold.\n\nThe appearence:\nBear-like Stovebellies are creatures living on titan. To keep warm, they have several features. They have a huge HUGE fur coat. The eat ice for moisture and to cool the ground the stand on. They also have a unique adaptaion to beath fire and fart out heat to go soaring. Salafishes, amphibious organisms, share a mutalion relation ship with stovebellies. They clear out ice blocks and act almost as dentistds for st

Not universal, just planetary.

i don't know if any earth-like planets exist, but i would be excited and not be surprised, if someone found any.

Personally I think the answer is "there aren't any," but there are some people who have made quite large lists of Earth-bound aliens. Note: these people often tend to think the Queen of England is a Reptilian, so keep that in mind.\n\nBasically you have the greys, reptilians, nordics, and those that look - and pass! - as humans. Or so they say.\n\nAnyway, here are some lists:

There are actually several "planet like" objects beyond Pluto in an area called the Kuiper belt that contains thousands of objects that circle the sun.\n\nAt present none of them have been officially recognized as new planets. \nThe discovery of these new planet size objects including  2003 UB313 (nicknamed XENA), Sedna(in 2004) and Quaoar(in 2002 by the same team) have triggered a re-evaluation of the necessary criteria to call something a planet.\n\nIt is likely that this team at Caltech will  discover other objects to be added to the list of potential "planets" in our solar system.\n\n2003 UB313(nicknamed XENA unofficially) is larger than Pluto which leaves officials in a bit of dilemna.  How can they recognize Pluto as a planet and not this object?

Okay, we are finding and discovering new forms of life all the time with new technology.  There are new marine animals found with the deeper we are able to explore.  Animals, bacterias, all forms of life are mutating and popping up all over the world.  On mars, they've discovered water on the planet and plant life under the surface of this water.  \nOkay, so it's not Star Trek yet.  We haven't communicated with alien beings...that we know of.  But that's not specifically what you asked now, is it?

I don't know for sure but the universe is just too freaking huge for humans to be the only life form in it.  So I believe that alien life forms have to exist out there somewhere, since the density of life through the universe has to be greater than null.

Even though we can't prove it, the answer is yes. The universe has billions upon billons of stars. So even if our planet was like 1 in a billion, there still would be 8 or 9 other planets like ours. How advance the civilization is, we cannot tell. This is in reference to intelligent life. As far as microscopic life, there well may be signs of this in our own solar system. Scientist at NASA have recently discovered liquid water under only tens of meters of ice on one of Saturn's moons. Along with this, they also discovered a thermal heat source at it's south pole, which is spewing water 300 miles into space. So this heat source and water may be home to microscopic organisms that have adapted to the cold of the moon. Hope this helps.

Don't forget the tenth planet "Xena"\n\nSome info on the planets:\n\nhttp://beaker.atspace.org/spaceglossplanets.htm

The newest one is Sedna. It's not a planet though.
