NEWS RELEASES
TIME TRAVEL THROUGH A TRAIL OF COMET DUST 
     If you’ve seen one comet, have you seen them all? Not

according to new NASA research.  Scientists believe they may one

day be able to travel through time by looking more closely at the

dust swirling with a comet as it hurdles through our galaxy. 
     The research also indicates that theories of how comets were

formed may need to be revised. 
     Comets are lumps of ice, gas, rock, and dust * frozen relics

from the birth of our solar system * that orbit the Sun.

Scientists now believe comets could have formed at different times

during the evolution of the solar nebula, and may reveal their age

by the structure of the dust they carry.

CUDDLING UP IN A QUILT OF GAMMA-RAY STARS 
     The Compton Gamma Ray Observatory is gone, but its memory

lives on — in a quilt museum located in a rural Virginia town. A

retired couple in Elkwood, VA took two gamma-ray images their son

received from NASA, back in 1993, and turned them into spectacular

coverlets.  One image, of the Crab and Geminga pulsars, is on

display through September 18 at the Virginia Quilt Museum in

Harrisonburg.  The second, of a gamma-ray quasar called 3C 279,

will have its first public viewing during a symposium on the

Compton mission July 19 at NASA’s Goddard Space Flight Center,

Greenbelt, MD.
