The Ring nebula has got its entire visible atmospheres completely flattened by its high intensity dual core polar vortices. This flattened atmospheres phenomenon has similar effects as the Saturn's Rings.

The Helix nebula is a short column hourglass shaped nebula, the mid intensity dual core polar vortices could not flatten its entire atmospheres, these have rendered the elongated eye-shaped hourglass pattern with a wobbling core. The Dumbbell nebula has this similar pattern.

The dual core polar vortices of these two nebulae are caused by their wobbling core.

The Hourglass nebula has low intensity polar vortices with a mildly wobbling core, these have rendered the long hourglass shape and a very circular column pattern.

The lower blue and white color atmospheres of these nebulae have been flattened to a disc shape.

The Southern Crab nebula has polar vortices of mid intensity with a mildly wobbling core, these have rendered the shorter column but very a circular hourglass pattern. The Red Square nebula has this similar pattern.

The Crab nebula and Cat's Eye nebula have extensively wobbling cores; the precession on rotating axis of those diffused stars has a very wide angle that causes the polar vortices pair to spin in a very unstable manner into these vortical asymmetric patterns. Crab nebula has low intensity polar vortices, unlike others such as Helix nebula, its lower blue and white color atmospheres were not flattened, and were also wobbling extensively. The combined effects of extensively wobbling polar vortices of several atmospheres rendered Crab nubela with these asymmetric patterns. The flame nebula has this similar pattern.

The Cat's Eye nebula believed to have a binary central star has mid intensity polar vortices and extensive wobbling core. The Stingray nebula has this similar pattern. See the force interactions of Cat's Eye nebula.

Do an experiment to spin an imbalanced hourglass structures held near the mid section to wobble them would yield optical images of asymmetric patterns similar to these nebulae.

The Butterfly nebula has low intensity dual core polar vortices and a moderately wobbling core. The green vortical glows are stellar jets and the hourglass shape purple grow is the upward vortical stream of ionized gas, these rendered the appearance of two long columns inside the hourglass pattern.

The NGC 6781 bubble-shaped nebula has high intensity polar vortices pair with an extensively wobbling core, These had caused the widely opened polar vortices pair to spin the atmospheres into a spherical shape pattern. The Abell 39 nebula has this similar pattern.

Do an experiment to spin a short cylinder object tied to a string as illustrated in the diagram on left, spin it fast enough would yield an optical image of a spherical shape. This would help to understand how NGC 6781 and some brown dwarfs have a spherical shape.

A nebula illustrated on left image with a flat disc shape atmospheres was not found, if existed it would have been caused by high intensity polar vortices pair with a mildly wobbling core.

The OTS 44, a brown dwarf, is remnants of stellar cloud that have consolidated into a disc shape. Its flat circular ring shape patterns are caused by high intensity polar vortices pair with a mildly wobbling core. Its faint grow is generated by a dynamo effect.

This flattened atmospheres phenomenon is similar to Saturn's Rings.

The images at right are some diffuse nebulae. Diffuse nebulae contain no well-defined boundaries, the atmospheres although have symmetrical patterns are still in chaos and have not yet consolidated from the diffused star. Its is known that the colors mainly come from scattered light absorbed by the atoms in the gaseous atmospheres.

The image on top right shows a false-color picture of Cat's Eye nebula, processed to reveal the enormous but extremely faint halo of greenish gaseous material, over three light-years across, which surrounds the planetary nebula. Excerpt from NASA - Astronomy picture of the day. This infers a huge torus shape spheroid of viscous mass that is encompassing this binary star system.

This is an evidence that infers there is a huge suspended spheroid of viscous matter encasing the nebula. Based on Universal Vortical Singularity, the rings suggest this is a top view on a polar region of the spheroid, these rings are the layers of torus shape magnetospheres of the binary star system. The spokes supposedly are long and thin satellite vortices formed around a huge polar vortex, this also infers that a huge spheroid of plasmic matter is encompassing the binary star system. With this suspended spheroid of viscous mass established, the vortices formed in its viscous mass can be logically comprehended based on singular vortex mechanism.

Torus shape structure

The pair of spiral arms suggest that the centre mass of this binary star system is rotating in anti-clockwise direction from this view. It is quite clear in the left image that the spiral arms are vortices and they are nicely formed. The invisible counter part of this visible dwarf star in the center is suspected to be a brown dwarf, the pair rotate and wobbles around each other in a common center. While one of the suspended spheroids is projecting forward in an angular momentum subjected to a cyclonical gravity field effect of the other suspended spheroid, the spheroid would thrust its lighter viscous mass vortically backward in the forward projection of its main mass, forming the very distinct vortical spiral arm as it has displayed. The similar effect on the other suspended spheroid within a common viscous mass in a mirrored manner would form the other vortical spiral arm in opposite direction, hence this opposite phases of vortices in corkscrew pattern are formed in a wobbling manner. This phenomenon is very similar to SS433 that are known to be a binary star system. Take a close look at these large vortices just inside their outer larger rings one can find satellite vortices around the rings; this is the vortical singularity of a singular vortex. Conjecturably this vortical force dynamics of satellite vortices in the outer rings could have consolidated plasma matter into comets by vortical compression, as would hailstones could be formed in whirling storm cloud in this similar manner.

These two stars of a binary star system would experience consistence rumbling earthquake-like oscillation on their surface as a result of strong external torque-induced precession on each other with their epic centers inside the main mass of the stars along the axes of the vortices. The force dynamics of spiral arim caused externally by the torque-induced precession would have pushed up a cone shape volcanoe on stratified surface that is encasing a suspended spheroid of molten matter, this force dynamics could also have caused volcano eruption. See a topic on earthquake and volcano eruption.

The asymmetric pair of spiral arms is caused by the binary stars revolving around each other, viscous mass of the revolving spheroids in the spin is pulled by an angular momentum therefore vortically dissipates away from the core by the drag. Although these spiral arms can be categorized as vortex by specification, and is a component of a singular vortex, they are not singular vortices.

See the image of comet Biela at right that has displayed a similar type of spiral arm when it got near the Sun, although a comet is too small relatively to Sun to able to cause a comparable spiral arms on the opposite side of the Sun from the comet, it could trigger sunspots on photosphere of Sun by its torque-induced precession. This spiral arm is formed inside the coma of this comet, the coma that encompasses a comet can be as big as one AU (astronomical unit) across. This image of comet Biela was taken in 1846 with spiral arms in its coma.
