Abell 39


Abell 39 - Planetary Nebula

Abell 39, a faint planetary nebula in the constellation Hercules. This deep space bubble is a planetary nebula which appears nearly perfectly spherical. The spherical shape is due to an expanding, glowing shell of ionized gas which was ejected from the evolving star. The central star is evolving into a hot white dwarf star. Because the gas is ionized, it is an emission type nebula. Abell 39 is approximately 6,800 light years away from earth.
