Saturn’s Hexagon "Recreated"

Unread postby Solar » Tue Jul 04, 2017 8:44 am

Physicists Ana Claudia Barbosa Aguiar and Peter Read of the University of Oxford in the United Kingdom wanted to see if they could recreate the hexagon in the lab. They placed a 30-liter cylinder of water on a slowly spinning table; the water represented Saturn’s atmosphere spinning with the planet’s rotation. Inside this tank, they placed a small ring that whirled more rapidly than the cylinder. This created a miniature artificial "jet stream" that the researchers tracked with a green dye.

Additional Paper:

We report a novel and spectacular instability of a fluid surface in a rotating system. In a flow driven by rotating the bottom plate of a partially filled, stationary cylindrical container, the shape of the free surface can spontaneously break the axial symmetry and assume the form of a polygon rotating rigidly with a speed different from that of the plate. With water we have observed polygons with up to 6 corners. It has been known for many years that such flows are prone to symmetry breaking, but apparently the polygonal surface shapes have never been observed. The creation of rotating internal waves in a similar setup was observed for much lower rotation rates, where the free surface remains essentially flat. We speculate that the instability is caused by the strong azimuthal shear due to the stationary walls and that it is triggered by minute wobbling of the rotating plate. The slight asymmetry induces a tendency for mode-locking between the plate and the polygon, where the polygon rotates by one corner for each complete rotation of the plate. – Polygons on a Rotating Fluid Surface Thomas R. N. Jansson et al


All of which begs the question: How does one get hexagonal-like craters on dry rocky bodies? Do dust particles 'electro-statically' adopt the fluid-like jet stream flow patterns?

H2O and hexagonal geometry could be the usual suspects.

Fluid dynamics is a result not a cause.

The cause is incoming charge (ie photons and ions/electrons), the Birkeland current.

Because charge (ie photons) has chirality, left and right spins, these spins oppose and thus sheets are created of different spin, this sets up the cylinders sheets that spin in opposite directions and that causes the diocotron instabilities in the fluids and thus a shape forms, round, hexagon, square...

From the TPOD, Saturn's Polar Vortex:

Hexagons and other polygons can sometimes occur in hurricanes, so astrophysicists believe that fluid dynamics can explain what they call a “mysterious” phenomenon. In 2010 physicists from Oxford University spun a 30-liter cylinder of water, with a ring of viscous green dye inside spinning faster than the cylinder. Their thinking was that a “jet stream” analogue could provide a plausible description of what is happening on Saturn if several factors are ignored.

First, they did not produce concentric rings around the hexagon, each with different temperatures. Second, Saturn’s poles are hotter than theories predict. Third, there are aurorae at the poles. Fourth, there is electric charge flow connecting Saturn’s poles to its family of moons. Additionally, the winds in the polar vortex are four times faster than any hurricane, nor does it move around. Such kinetic experiments are insufficient in scope, since electrical effects are not considered. Perhaps the kinetic model should be stood on its head: the polygons in hurricanes should be reevaluated in the light of electrical theories.

Electricity flowing through plasmas can create a central column surrounded by concentric cylinders, as retired Professor of Electrical Engineering, Dr. Donald Scott proved. Filamentary structures form evenly spaced vortices surrounding the column. As the filaments rotate around one another, a hexagonal cross-section forms inside.

A picture is worth a 1000 words. At both ends of these filaments in a plasma ball, in proximity
to an electrical field, you will see that the stabilizing effect also produces hexagonal boundaries.

This image is focused on the root of the filament showing the hexagonal boundary.

Surely not Cassini's Final Image.

Cassini managed to take a final monochrome image hours before splashdown?
I thought hours would have been enough time to take a few more photographs.
Maybe even a last photo or two after entering the atmosphere?

I read on, to see why that was the last image, when the descent still had hours to go.
No explanation.
As if we should consider it normal that they switched the cameras off hours early.

But I cannot believe they did.
That is just the final image that they are giving us.

Then, they also show us this.

A natural color view, created using images taken with red, green and blue spectral filters, of the last image taken by the imaging cameras on NASA's Cassini spacecraft.
They take color filtered images of the monochrome image, to create a natural color view?

Does that sound right to you?

They're messing with us, I tell you.

It is my understanding, from the public radio discussions, that they turned off the camera when they no longer had enough time to transmit the photos.

Thank you, Jac.
I understand your point. The images files are big, and take time to transmit. But hours?

I expected the last image should have been a partial image, which got cut off when the transmitter failed, or the signal got obscured by the atmosphere.

I can't see the point in turning any instruments off during the descent.

STRONG ELECTRIC COUPLING BETWEEN RINGS AND IONOSPHERE

The instrument, a so-called Langmuir proble, was developed at the Swedish Institute of Space Physics in Uppsala. The upper atmosphere of Saturn is charged and consists primarily of hydrogen and hydrogen ions. The Langmuir probe can be compared with a weather station for electrically charged gas; it measures its density, temperature and velocity. It also measures particles’ energy and moreover gives a rough estimate of what the gas consists of.

”The first results are surprising,” says Jan-Erik Wahlund, IRF, principle investigator and responsible for the Langmuir probe on Cassini.
Strong variations in density indicate that the electrically charged part of Saturn’s atmosphere (the so-called ionosphere) has a strong coupling to the visible rings that consist primarily of ice particles. The ice particles are also electrically charged.

”It is as though the small ice particles in the D-ring suck up electrons from the ionosphere,” says Jan-Erik Wahlund. ”As a result of the coupling, electrical flows of gas to and from the rings along the magnetic field of Saturn cause the greatest variations in density.”

That is a great discovery and confirmation of Birkeland's model. This century could get known to be the century where most electrical predictions in our direct stellar neighbourhood will be confirmed.

Saturn's magnetic field is getting WEIRDER say scientists studying data from Cassini

Scientists are surprised by some of the data that the probe Cassini beamed back before burning up in Saturn's atmosphere
https://www.mirror.co.uk/tech/saturns-magnetic-field-getting-weirder-13361809

According to a new paper from Imperial College , Saturn's magnetic field is refusing to confirm to existing thinking.

The findings, which appear in a Cassini end-of-mission results article in Science, show that Saturn's magnetic field has a tilt of less than 0.01 of a degree.

Scientists had previously thought that a planet could only form a magnetic field if there is discernible tilt. Earth's, for example, is 11 degrees.

Professor Michele Dougherty explained that measuring the tilt itself is also challenging. "Each time we more accurately measure the tilt of Saturn's magnetic field, it gets smaller, until now we are in a position where it is smaller than a hundredth of a degree."

The tilt is important because it sustains currents in the liquid metal layer deep within the planet. On Sarth the liquid is iron-nickel surrounding the solid iron core.

Saturn's core is thought to consist of a metallic hydrogen layer around it's small, rocky core.

There's a possibility that the atmosphere on the planet is obstructing Imperial's magnetometer which was onboard the Cassini probe. However scientists still think this might change how they look at magnetic fields.

Saturn might also have more than one way of generating magnetic fields, with a deeper layer made up of liquid hydrogen producing small, stable fields.

Even weirder is the discovery that an electrical current flows from the D ring of Saturn to the planet's surface.

Despite burning up in Saturn's atmosphere in September 2017 the mission is still yielding interesting data.

The Imperial team is also considering combining results from the magnetometer with gravity data to build a more accurate picture of the size, mass and density of Saturn's core.

While it's unusual to hear scientists describe things as weird, but Saturn's mysteries do often give experts some real head scratchers.
