Three Faint Companions of Bright Stars Discovered with New Infrared Camera Developed at Penn State
A Gaussian pupil mask designed for deep contrast imaging for faint companions around bright stars. This is the new generation coronagraph technique being supported by NASA for further technology development for the Terrestrial Planet Finder.
Astronomers Use X-Rays to Probe Gravitational Field of a Neutron Star
This artist's conception illustrates 1E 1207.4-5209, a neutron star with a polar hot spot and a strong magnetic field (purple lines).
Penn State Astronomer's Images of the First Stars Featured on Discovery Channel During June
The first galaxies form hierarchically. Small object form at the intersection of filaments and merge into larger and larger objects. When these pre-galactic objects become as heavy as a million times the mass of our sun one massive star forms within them. (See copyright information below.)

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
