Do you think there is life on Mars?

I think the temperatures are too extreme for life as we know it. There is a four hundred degree ( Fahrenheit ) difference between night and day.

No, aliens are not living on Mars at the present time because the current conditions there could not support life. There is a possibility that life once existed there, based on evidence of previous existence of water. The "face" and "pyramids" that you're talking about on Mars are just glitches in the photography that have been proven to be incorrect.

having life only exist on earth is like picking up a single grain of sand and saying that that grain was the most perfect grain in the entire world...it would be impossible to know this unless every other grain was examined, and the fact the new grains are constantly being made.  there are over 200 billion galaxies in the visible universe and a couple hundred billion more out there, all containing stars and planets that maybe able to sustain life.  and by "life" that also takes into account of any micro-organisms like bacteria and viruses and any other forms of life that might exist.  So to say that there is no life on other planets would be incorrect to assume, it's just a matter of time in trying to find it, whether it exists in our solar system is still debatable as micro-organisms can live in harsher conditions that larger organisms arent able to

It may well be!\n\nThe problem is that we haven't really looked. It's true that the probes we've sent around our own solar system have drawn a blank when it comes to life. Life as we know it seems to prefer a certain range of temperatures and habitats, and those conditions aren't all that common. But they do exist, both here in our solar system and (almost certainly) in other solar systems as well.

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!

Yes, I do believe that life does exist in the universe on other planets. its doesnt mean that life is there only on Earth n in our solar system of the STAR SUN.\nIf u c there r millions of stars in the universe and triliions of planets so there is a possibility to find a planet similar or exact as EARTH which has the same atmosphere or maybe the same gravitational field or perhaps the same solar system is repeated somewhere in the universe.

Wasn't that the Mars landing?  Looking for life out there.

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?

1.  On Mars, yes.  It's only microscopic life though.  Sedna, I have no clue.\n\n2.  Go here.  It'll provide a great answer to your question.  http://www.pbs.org/wgbh/nova/sciencenow/3210/01.html

Well Scientists have long speculated about the possibility of life on Mars due to that planet's proximity and similarity to Earth. It remains an open question whether life exists on Mars now, or existed there in the past.\nIt has long been speculated that there may be life on Mars, due to the many similarities the planet has with Earth. Mars' polar ice-caps were observed as early as the mid-17th century, and they were first proven to grow and shrink alternately, in the summer and winter of each hemisphere, by William Herschel in the latter part of the 18th century. By the mid-19th century, astronomers knew that Mars had certain other similarities to Earth, for example that the length of a day on Mars was almost the same as a day on Earth. They also knew that its axial tilt was similar to Earth's, which meant it experienced seasons just as Earth does - but of nearly double the length owing to its much longer year. These observations led to the increase in speculation that the darker albedo features were water, and brighter ones were land. It was therefore natural to suppose that Mars may be inhabited by some form of life.\n\nSpeculation about life on Mars exploded in the late 19th century, following telescopic observation of apparent canals — which were later found to be optical illusions. In 1854 William Whewell, a fellow of Trinity College, Cambridge, who popularized the word scientist, theorized that Mars had seas, land and possibly life forms. In 1895, American astronomer Percival Lowell published his book Mars, followed by Mars and its Canals in 1906, proposing that the canals were the work of a long-gone civilization. This idea led British writer H. G. Wells to write The War of the Worlds in 1897, telling of an invasion by aliens from Mars who were fleeing the planet’s desiccation.\n\nBetter telescope imagery, and especially the photos taken by the Mariner 4 probe in 1965 showed an arid Mars without rivers, oceans or any signs of life. Intense UV radiation made the planet extremely hostile to life as we know it. Officially the Viking lander's tests for microbes in 1976 were inconclusive, but most scientists hold that their findings can be explained on the basis of chemical reactions alone. Observations made in the late 1990's by the Mars Global Surveyor confirmed the suspicion that Mars, unlike Earth, no longer possessed a substantial global magnetic field, thus allowing potentially life-threatening cosmic radiation to reach the planet's surface. Scientists also speculate that the lack of shielding due to Mars' diminished global magnetic field helped the solar wind blow away much of Mars' atmosphere over the course of several billion years.\n\n\n\n \nThe electron microscope revealed bacteria-like structures in meteorite fragment ALH84001 \nA series of artist's conceptions of hypothetical past water coverage on Mars.In recent years speculation has grown again, however – prodded by a study of the ALH84001 meteorite which concluded that it contained fossilized microbes. Other scientists have subsequently sought to explain these findings on the basis of chemical processes. Both remain highly controversial within the scientific community.\n\nAnother glimmer of hope for past and present life on Mars has been revealed with the ongoing research into extremophiles on Earth which survive under the harshest conditions. Some scientists have proposed a biological origin for the annual appearance and disappearance of dark dune spots near the polar regions of Mars.\n\n\n\nNo Mars probe since Viking has tested the Martian soil directly for signs of life. NASA's recent missions have focused on another question: whether Mars held lakes or oceans of liquid water on its surface in the ancient past. Many scientists have long held this to be almost self-evident based on various geological landforms on the planet, but others have proposed different explanations - wind erosion, carbon dioxide oceans,

Yes. They are probably microbes or even smaller nanobacteria. \n\nI have seen the work of Dr. Robert Folk at the University of Texas, who examined the Martian meteorites found in Antarctica and found possible fossil evidence of nanobacteria. Many biologists are not convinced that nanobacteria (which are measured in nanometers) even exist and argue that they are too small to contain the functions of a living cell. The topic remains controversial.   \nHere is a page discussing the biological controversy (there are some geological controversies as well):\nhttp://serc.carleton.edu/microbelife/topics/nanobes/index.html\n\nHere is the NASA page describing the findings:\nhttp://nssdc.gsfc.nasa.gov/planetary/marslife.html

I don't know about experiments and alien visits. But I know that I'd like to think that there is more out there some where. I don't even know if there is a chance that other intelegent life exists for not but I can't help but think that other planets in the universe have to be suitable for some form of life and continue to sustain something. We may never find it or know about it, especailly in this life time but there has to be more than just Earth.

I wouldnt say there isnt any life outsdide our solar system. there can be a very high possibility that there is inteligent life out there.

No.. although the rovers did find pebble shaped objects which suggest the previous existence of water, and hematite an iron based rock usually found around water.  No life, only the possibility of previously existing life.

if theres not i would be extreme surprised.  the universe is so huge that it would be ridiculos to assume or think there isnt.  even though we have only explored probably less then 1% of the universe we have still found planets that we think would be able to suport human life (remember not all life would have to be carbon based like us either) so even if there isnt a planet that we could live on some other type of creature might think its paradise.  the answer to your question is yes there is most likely life other then ours out there somewhere. although it would depend on what you mean by "life" if you mean intelligent life i still think yes there probably is although they have found fossils of bacteria on mars so technically that means there was at one point there was life in our solar system other then earth.

No. There would have to have been millions of years of carbon-based life. That's one of the reasons oil is referred to as a "fossil fuel"; it really is one of the byproducts of the biosphere.\n\nThere's no evidence of life ever having existed on the moon, and no evidence yet of any on Mars - now or in the past.
