The search for extreterrestrial organisms spans far and wide.  From the S.E.T.I. program which began in the 1970s to the search for exoplanets, many different approaches have been taken.  Extraterretrial life and/or simple organisms could possibly be found on other planets and moons in our very own solar system.  At least this is what some astronomers think.  What is your opinion?

Could there be life on Saturn’s large moon Titan? Asking the question forces astrobiologists and chemists to think carefully and creatively about the chemistry of life, and how it might be different on other worlds than it is on Earth. In February, a team of researchers from Cornell University, including chemical engineering graduate student James Stevenson, planetary scientist Jonathan Lunine, and chemical engineer Paulette Clancy, published a pioneering study arguing that cell membranes could form under the exotic chemical conditions present on this remarkable moon.
