New research from NASA's Cassini spacecraft's up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its rings and its moon Enceladus. The observations show for the first time that the waves travel on magnetic field lines connecting Saturn directly to Enceladus. The field lines are like an electrical circuit between the two bodies, with energy flowing back and forth.

Researchers converted the recording of plasma waves into a "whooshing" audio file that we can hear—in the same way a radio translates electromagnetic waves into music. In other words, Cassini detected in the audio frequency range—and on the ground, we can amplify and play those signals through a speaker. The recording time was compressed from 16 minutes to 28.5 seconds.

Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The Radio Plasma Wave Science (RPWS) instrument on board NASA's Cassini spacecraft recorded intense plasma waves during one of its closest encounters to Saturn.

"Enceladus is this little generator going around Saturn, and we know it is a continuous source of energy," said Ali Sulaiman, planetary scientist at the University of Iowa, Iowa City, and a member of the RPWS team. "Now we find that Saturn responds by launching signals in the form of , through the circuit of connecting it to Enceladus hundreds of thousands of miles away."

Sulaiman is lead author of a pair of papers describing the findings, published recently in Geophysical Research Letters.

The interaction of Saturn and Enceladus is different from the relationship of Earth and its Moon. Enceladus is immersed in Saturn's magnetic field and is geologically active, emitting plumes of water vapor that become ionized and fill the environment around Saturn. Our own Moon does not interact in the same way with Earth. Similar interactions take place between Saturn and its rings, as they are also very dynamic.

The recording was captured Sept. 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn. The recording was converted by the RPWS team at the University of Iowa, led by physicist and RPWS Principal Investigator Bill Kurth.

Not to say it, but yeah told you...

The only message that actual 'plasma cosmology' advocates wanted to get through was that the ideas they support have real scientific merit.
It's not unforgivable belief into an obviously quack pseudoscience... its the idea that mainstream science has become built upon a shaky, biased foundation that has proved to be unfalsifiable.

In the smallest sense, this finding illustrates another possible energy source which can produce alternate mechanisms that more simply explain the moon's tiger stripes, 'cryovolcanoes', plumes, jets, surface heating, etc.

Why did it take so long to 'discover' these currents between Saturn and Enceladus?

I wonder how long before electrical interactions between the Sun and the heliosphere, comets, etc. are found...


Jul 10, 2018
Mainstream science doesn't deny solar wind travels out to the edge of the solar system. The issue is; there is no direct current (DC) flow within the solar system coming from outside the solar system, which powers the Sun.
How large does the voltage have to be outside the solar system to have a double-gap the size of the solar system? I can only figure the EU folks would question this.

Never, would be the answer to that, given that we have had spacecraft buzzing around the solar system as far as the heliopause for decades, and have recently completed a two year + mission at a comet, where we find precisely nada of the nature proposed by EU wooists.

This statement is a fallacy which I already addressed.

How long have we had spacecrafts buzzing around Saturn and we are only now confirming the existence of an electrical circuit between Saturn and its moons?

And pretty sure we've only just reached the heliospheric boundary... which led to "surprising magnetic bubbles."

Jul 10, 2018
LOL, who's claiming this woo is real? Given jonesdumb's continued ranting from ignorance he just doesn't get it.

A similar process is likely responsible for comet 67P and it's "singing".

Bit by bit the standard theory is falling apart while the Electric Universe cosmology is getting more and more robust.

Hmmm, I think I know the lead author of the paper on the 'singing comet'. Care to debate him on ISF? Given that he is qualified in plasma physics, and you aren't, expect an arse kicking. However, we all know that you'll never take your woo to an actual science site. Prove me wrong.

Hey, dumbo, read the literature. Try to understand plasma physics, yes? Just like Io, Enceladus is spewing out neutrals, which become ionised (look it up), and this ionosphere is orbiting within a magnetosphere of a planet at a different velocity than the magnetosphere. What do you expect to happen? Nothing to do with any idiocy dreamed up by idiots like Thornhill, yes?

Keep up, 691! The current is going INTO the Sun! Still invisible and undetectable, though. If you ask the EU loons, they'll tell you that it is due to it being a 'drift current', and therefore very difficult to detect. Totally overlooking the fact that the speed of the electrons (?) are irrelevant. It is the speed with which they hit the spacecraft detectors. Which are moving at the same velocity as the spacecraft. Which is considerable, relatively.

says gculpex

From your link: "Dr. Morley added: "Previously, drag forces from wind or thermals were thought responsible for this mode of dispersal, but we show that electric fields, at strengths found in the atmosphere, can trigger ballooning and provide lift in the absence of any air movement. This means that electric fields as well as drag could provide the forces needed for spider ballooning dispersal in nature."

also

"...a global electric circuit that is always present in the atmosphere..."

Hmm atmospheric electric circuits. Can this be?

Just wondering. Could that "singing" be compared to the old telegraph wires in the old mid and western parts of the US in the late 1800s. The Native-Americans of the time said that the telegraph wires were singing.

"Hmm atmospheric electric circuits. Can this be?"

Sometimes they are really powerful and go by the moniker of "lightening".

I really do not understand (nor do I wish to so no explanation necessary) as to why certain types rail against evidence and observations that have clearly defined mechanisms behind their manifestation when they could, instead, accept the enlightenment that comes with new understanding. These are the guys still wanting to throw virgins into the volcano to prevent it from erupting while the rest of the population comes to realize you can't plug a lava tube with a 90LB human.

It really does take all kinds....

You ridicule because you claim that the current is "invisible and undetectable" yet we see the expected results from this phenomena so we "know" it must exist.

Wait... are you describing dark matter?

Jul 11, 2018

The movement of plasma, neutrals, and electric charges within electromagnetic fields and interacting with charged bodies which absorb, store, and discharge the EM energy that travels through them is not a "valid scientific mechanism".
Alrighty then! De Nile is in Egypt, you however reside at intersection of denial and willful ignorance.

Typical double standard applied by the DM/BB religionists.

Of course. I was just being facetious with an attempt at being a smart-aleck. But I enjoyed the link that you provided. So much so that I decided to search for a more recent article...and found this:

And thanks again for that link.

No, we don't see it. The Sun is powered by nuclear fusion. Show me evidence to the contrary. And dark matter can be detected, and has been, due to its gravitational effects.

The priori of a gravity based reality forces the assumption of Dark matter because the math does not work without it. An EM based reality does not need it.

yep
Jul 13, 2018
This priori of gravity was also Eddington's template giving us a thermonuclear core that defies all observable evidence. More math taken as empirical evidence by consensus stooges worshiping at the alter of authority and its non falsifiable gravity god.
