Planets of the Phoenix: Astronomers Predict Rebirth of Planetary Systems in the Embers of Dead Stars
A diagram of how planets become unstable around white dwarfs. As a star becomes a white dwarf the planets expand their orbits slowly. They then become unstable and experience chaotic orbits that eventually become radically different, drastically affecting their surroundings. This illustration was created by actual output of computer simulations performed at Penn State and presented at the American Astronomical Society meeting in Washington, DC on 7 January 2002 PHOTO CREDIT: John Debes, Penn State

Understanding the relations between the geology, the chemistry and the biology of hydrothermal systems is the cornerstone of the integrated studies theme. Pictured is a colony of giant tubeworms with vent fish and crabs, all highly specialized for and found only in the extreme environment of the hydrothermal vent ecosystem.
