HUBBLE PROBES THE COMPLEX HISTORY OF A DYING STAR
EMBARGOED UNTIL:  9:00 A.M. MST, January 11, 1995
PHOTO RELEASE NO. :  STScI-PRC95-01

This color picture, taken with the Wide Field Planetary Camera-2,  is a
composite of three images taken at different wavelengths. (red,
hydrogen-alpha; blue, neutral oxygen, 6300 angstroms; green, ionized
nitrogen, 6584 angstroms).  The image was taken on September 18, 1994.
NGC 6543 is 3,000 light-years away in the northern constellation Draco.

The term planetary nebula is a misnomer; dying stars create these
cocoons when they lose outer layers of gas.  The process has nothing to
do with planet formation, which is predicted to happen early in a star's life.

This material was presented at the 185th meeting of the American
Astronomical Society in Tucson, AZ on January 11, 1995.
