Extraterrestrial life is defined as life that does not originate from Earth. Possible forms of extraterrestrial life range from simple bacteria-like organisms to sapient beings far more advanced than humans. It is unknown whether any such forms of life exist or ever existed. Tonight at our astronomy meeting, Dr. Urszula Golebiewska who specializes in physiology and biophysics and does research in cellular biophysics was the speaker. She gave a wonderful talk starting with defining what life is, exactly, and then what is necessary for it to form and flourish, and then where we might look for it in the solar system, and beyond. A wonderful talk for an enthusiastic audience!
