Astronomers have discovered dozens of planets orbiting
other stars, and space probes have explored many parts of
our solar system, but so far scientists have only discovered
one place in the universe where conditions are suitable for
complex life forms: Earth. In this unit, examine the unique
characteristics that make our planet habitable and learn howthese conditions were created
