The Hunt for Life Begins

Abstract

For centuries, and likely millennia, humans have tried to figure out their place in the universe. For many scientists, astronomers, and planetary scientists the answer lies not with Earth itself but far out into the Solar System, in the planetary neighborhoods of distant suns. It would seem, then, that finding life elsewhere in the universe may be the key to understanding life here on planet Earth. So scientists around the world go about studying the worlds of our Solar System and the galaxy we live in. For if we can find a sign of life living away from the relative calm of Earth, it may be that the requirements for life can be met throughout the galaxy and even the universe at large.
