JS Delaney Chemistry Chem i cal B i ology Rutgers University Piscataway NJ08854 Introduction Formation of planetesimals asteroids pla n etoids from early Solar system materials requ. The Birth and Evolution of Planetary Systems. Where did the solar system come from? How was it made?. Up until the mid 1990’s the only planets known were those in our solar system. As a result, the theories we developed to explain the formation of a solar system fit our system. Since the 1990’s we have discovered hundreds of extra-solar planets. How does our theory match these newly discovered worlds? . Early Life on earth. The evidence for the earliest life is highly controversial and still debated. Much of the debate surrounds the oldest . fossils.. The timespan that considers the biological and geological context for the emergence of life on the Earth includes the . Comets. one of the most glorious things to see in the sky is a comet.. May be visible for only days, weeks, or months. Comet. : chunks of ice and dust whose orbits are very long, narrow ellipses..
