| Description |
The Blinking Planetary Nebula is a beautiful remnant
from an ordinary star that has just recently gone through its red giant
phases, casting off most of it outer layers of matter, and is now a
degenerate white dwarf. The extreme ultraviolet from the hot young
stellar corpse is providing the energy to light up the nebula.
