Cassini sees something

That cant be moving withing the rings, it must be below them as theres no gravitational effects shown on the rings, if it was close or within the ring there wouldve been like a wave effect on the rings from the gravitational pull.

Colossal Structures Discovered Towering Above Saturn's Rings

This one is a 10 on the Galaxy wow meter: In images made possible only as Saturn nears equinox, NASA's Cassini spacecraft has uncovered for the first time towering vertical structures in the planet's otherwise flat rings that are attributable to the gravitational effects of a small nearby moon. The search for material extending well above and below Saturn's ring plane has been a major goal of the imaging team during Cassini's "Equinox Mission," the two-year period when the sun is seen directly overhead at noon at the planet's equator. This novel illumination geometry, which occurs every half-Saturn-year, or about 15 Earth years, lowers the sun's angle to the ring plane and causes out-of-plane structures to cast long shadows across the rings' broad expanse, making them easy to detect.

In recent weeks, Cassini's cameras have spotted not only the predictable shadows of some of Saturn's moons, but also the shadows of newly revealed vertical structures in the rings themselves. And these observations have lent dramatic support to the analysis presented in today's publication that demonstrates how small moons in very narrow gaps can have considerable and complex effects on the edges of their gaps, and that such moons can be smaller than previously believed.

"We thought that this vertical structure was pretty neat when we first saw it in our simulations," said John Weiss, the paper's lead author and a research associate of Cassini imaging team leader Carolyn Porco, another co-author on the paper, in Boulder, Colo. "But it's a million times cooler to have your theory supported by such gorgeous images. It makes you suspect you might be doing something right."

hey concrete nice find..I will copy your post into my thread topic4532-10.html ...it will be a good implication .ok

Could it not be a shadow behind the object?

Saturn is so fucking weird! I love it! Just too much strange sightings like all the motherships around it! That sphere sticking out of the rings does not look like natural phenomena to me. Nor does the 1300 ft sphere. We need more probes up at saturn! :flop:

If Saturn has so much strangeness to offer; I wonder what Jupiter has to offer. I think that both Saturn and Jupiter and their moons are magnificent by any standards, and that Jupiter was meant to be a second sun to make this a binary star system.

This solar system has so much to offer, and we have only touched on the ebb of this wonderful star system.

Jupiter was never meant to be a second sun, its just a large planet, there are planets similar to it in almost all systems weve looked at upto now, nothing strange about it.

If its not mars its suturn and its freaky rings, we need to get out there dont we? I hope someone with lots of money and friends who are engineers gets inspired by this and forms a nice shiny new space agency, free from the doubt and paranoia that surrounds NASA.

:wink:

Im not realy that sure, but as far as i knew Jupiter hasnt the mass to become a star, maybe if it had been able to accumulate more mass it couldve became one, also multiple Jupiter size planets have been found in other systems suggesting there not that rare or special.
We use the wobble observed in these other Jupiter like planets to find smaller ones, so there not that rare in other systems.

*Intresting about the radiation, i hadnt heard that before.

Yep, it was once thought jupiter was just shy of being a star. We now know that there are planets hundreds of times larger than jupiter that are not even close to ignition as well.

We also know now that two stars could not coexist that close in a stable system. Not even a brown dwarf could hold a steady orbit this close to sol. The extra radiation from jupiter is believed to be from the fact its a warm gas giant as opposed to a cold one like neptune or even Saturn.

We actually don't use jupiter like planets or their wobble to find planets. We use stars for that. Planets are too dim to observe. That's how we find out about these other jupiter types.

Oh yeah lol its the star we look at :bang;

, its not the plantes we see but the stars, and the effects the planets have upon them.
