Astronomers have named these features of a
planetary nebula "cometary knots" because of their resemblance to giant
comets. From an Electric Universe point of view, the resemblance may be
more than visual.
As long ago as the 1940¹s, an electrical researcher,
Dr. Charles Bruce of England, identified planetary nebulae as stellar
electric discharge phenomena.
Although the heads, or comas, of these "comets"
are twice the size of our solar system and much dustier than our comets,
their electrodynamics is essentially the same. The coma of a solar
system comet is generated by the difference in electrical potential
between the nucleus and the surrounding plasma. A charged body placed in
plasma forms a cocoon around itself, called a Langmuir sheath or plasma
sheath. The cocoon isolates the charge on the body from the surrounding
plasma. At the sheath boundary, two layers of charge, called a |"double
layer," take most of the electrical stress. If the electrical stress is
high enough the plasma sheath may glow.
The changing electrical stress on a comet is due
to its highly elliptical orbit. The Sun has a weak radial electrical
field. A comet spends most of its time far from the Sun and becomes
adjusted to the voltage there. As it zips in for a quick fly-by of the
sun, the voltage and charge density of the solar plasma changes rapidly,
generating increasing electrical stress on the comet. When the
electrical stress is high enough, the comet¹s plasma sheath lights up to
form the classic cometary spectacle. The comet nucleus begins
discharging and the resulting cathode jets sweep back to form a tail
that is "blown" in a direction aligned with the Sun¹s electric field.
The same thing would happen to an object of any
size on a cometary orbit through the Sun's electric field. If the Earth,
which is a charged body, were on a cometary orbit, its magnetosphere
would glow. Similarly, the objects forming the cometary knots of the
Helix Nebula are responding to the strong electric field centered on the
star outside the picture at bottom right.
