Extraterrestrial life is defined as life which does not originate from planet Earth. It is the subject of astrobiology and its existence remains hypothetical since to date no credible evidence of extraterrestrial life has been discovered which has been generally accepted by the mainstream scientific community. Hypotheses regarding the origin(s) of extraterrestrial life, if it indeed exists, are as follows: one proposes that it may have emerged, independently, from different places in the universe. An alternative hypothesis is panspermia, which holds that life emerges from one location, then spreads between habitable planets. These two hypotheses are not mutually exclusive. The study and theorization of extraterrestrial life is known as astrobiology, exobiology or xenobiology. Speculated forms of extraterrestrial life range from life at the scale of bacteria to sapient or sentient beings. Suggested locations which might have once developed, or presently continue to host life similar to our own, include the planets Venus and Mars, moons of Jupiter and Saturn (e.g. Europa, Enceladus and Titan) and Gliese 581 c and d, recently discovered to be near Earth-mass extrasolar planets apparently located in their star's habitable zone, and with the potential to have liquid water.

Answered by Justin - Tue Sep 30 05:32:18 2008 How do you imagine extraterrestrial life? Q. So it is almost a guarantee (I believe) that there is extraterrestrial life somewhere in this universe. For those who feel the same, what do you imagine these "aliens" look like? Do they look like our human race, considering they evolved like us, or are they totally different, evolving to fit the needs of the planet they inhabit? I'm assuming the latter because, depending on which planet you are from, should determine how you evolve to adapt to your surroundings. We also must consider that other living beings may not be as far evolved as we are, or they may be millions of years ahead of us. Any thoughts? Asked by Jimi - Fri Apr 17 02:38:19 2009 - - 7 Answers - 0 Comments A. I would guarantee different. Think about the dissimilarities between humans (homo sapiens) on this ONE planet (dark skin for sunlight in warm regions, thin slanted eyes for wind protection in Asia, straight hair for heat retention in cold areas such as Europe) and between now-extinct hominids (homo neanderthalensis, homo erectus, homo floresiensis, etc; you get the picture.) The sheer mathematical diversity (200-400 billion stars in our galaxy alone, most believed to be orbited by planets; 100 billion+ galaxies in the observable Universe...) indicates that anything from another planet will TRULY be alien. I believe that imagining them truly defies our ability until we have life or specimen from another world on which to base it. Answered by unknown - Fri Apr 17 02:59:40 2009 Why do scientists feel all extraterrestrial life forms must ahere to the rules of earth?
Q. i.e. they must breath air, they would not be able to live in extreme temperatures, they have to eat, etc. etc. Why couldn't a being live on Mercury, not require sustanace or water, and still be intelligent and reproduce? Why must everything conform to our preconcieved notions of how things are? Asked by Seeker? - Tue Jun 27 03:53:07 2006 - - 6 Answers - 0 Comments A. It's because we are the only planet with living beings that we know of so we only have Earth as an example of what living things need.
