With the discovery in the last ten years of more than 150 planets outside our solar system, people are truly beginning to think that life out there is possible—although the idea still leaves some people snickering. Now several universities offer courses in exobiology, which is the study of extreme life forms. And NASA has several exobiologists doing research into extreme life forms right here on Earth. Extreme life forms are those life forms that live in environments that would kill you or me. Did you know that here on Earth there are animals that never see the Sun and live by eating rocks? Others live underwater where the temperature is above the boiling point and the pressure is 3,000 pounds per square inch! That is like having a small car sitting on your back. Yes, these things occur right here on Earth—and that is why scientists believe just about anything is possible.
