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

Scientists Find X-Rays from Stellar Winds That May Play Significant Role in Galactic Evolution
A smoothed X-ray map of the Rosette Nebula region. The colors represent the energy of the X-radiation: red shows low-energy (0.5-2 keV) X-rays while blue shows high-energy (2-8 keV) emission. The mosaic is formed from four ACIS images, starting with the OB association at the center of the Rosette Nebula on the right and stepping southeast (left) into the Rosette Molecular Cloud.
