JPL -- NASA's Spitzer Space Telescope has spotted what may be comet dust sprinkled around the white dwarf star G29-38, which died approximately 500 million years ago. The findings suggest the dead star, which most likely consumed its inner planets, is still orbited by a ring of surviving comets and possibly outer planets. This is the first observational evidence that comets can outlive their suns. "Astronomers have known for decades that stars are born, have an extended middle age, and then...

NOAO -- New Spitzer Space Telescope observations of an unusual class of interacting binary stars detected excess amounts of infrared radiation, suggesting that these odd objects are surrounded by large disks of cool dust. The results reported today in Washington, DC, at the 207th meeting of the American Astronomical Society (AAS) were produced by one of six teams of professional astronomers and high school teachers participating in a unique program co-sponsored by the Spitzer Science Center...

Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust -- a discovery that may provide insights into our own solar system's eventual demise several billion years from now. The results are based on mid-infrared observations made with the Gemini 8-meter Frederick C. Gillett Telescope (Gemini North) on Hawaii's Mauna Kea. The Gemini observations reveal a surprisingly high abundance of dust orbiting an...
