A Planet's Rocky Road to Success

With the Spitzer telescope, we have been able to detect
debris analogous to the zodiacal cloud and Kuiper Belt in
literally hundreds of nearby planetary systems. Studies of this
debris are giving unprecedented insights to the development
of terrestrial planets during the critical periods in the life
of the earth: 1.) the impact that formed the moon; 2.)
the Late Heavy Bombardment that terminated planet building;
and 3.) setting the stage for the emergence of life. We see similar
patterns emerging around other stars and can use them to test
theories of how the solar system evolved.
