What Might Affect Alien Life?

Location, Location, Location. It might not matter on how far from a star the planet/moon is, but on how geologically active it is. Triton, a moon orbiting around Neptune over 2 billion miles away from the sun, may support bacterial life forms. Triton is home to a deep system of hydrothermal vents, with ammonia ice slush on the surface and warmer, possibly liquid soup in its interior. Io is the most volcanically active body in our solar system, with its molten surface always changing due to the intense gravitational pull of Jupiter. Europa may have a vast ocean under its surface, though we do not know how earth-like life may breathe here. Mars, a likely candidate, was likely to have had previous life; any present life is deep under the surface. Venus may host many species of extremophiles living off of its carbon atmosphere. Triton has many methane lakes larger than Lake Michigan, and "snow" that creates dunes over 7 x the size of those on Earth. These diverse enviornments may harbor life very different from our own.
