World’s Biggest Diamond Ring – Reigning majestically from the chilly, dark outer kingdom of the Solar System, a quartet of enormous gaseous planets circle our Star. Saturn and Jupiter are our Solar System’s gas giant duo, and the two are shrouded by heavy, dense envelopes of gasoline. Saturn is the bigger of both gas-giants, but it’s larger than both other, more distant planetary denizens of the Solar System’s outer limits–Uranus and Neptune–which are classified as ice-giants since they contain larger cores shrouded under thinner gaseous envelopes of blanketing gas. Saturn is a gorgeous, distant world, famous for its enchanting, bewitching, and lovely system of rings, which are largely composed of a dancing multitude of tiny, twirling icy fragments. The rings of Saturn would be the most extensive planetary ring system of any planet in our Solar System, also in September 2015, a group of astronomers reported that their research indicating that the icy bits tumbling around in 1 part of Saturn’s rings are denser than everywhere, which this is possibly due to solid, icy cores. This finding could indicate that this particular ring is considerably more youthful than the others.

Back in August 2009, a distant sunset on Saturn’s mesmerizing rings had been closely observed by astronomers that were part of NASA’s Cassini mission. It had been the equinox–just one of 2 periods of the Saturnian year if our Star shines brightly on the planet’s immense and majestic system of gossamer rings edge-on. The event provided a valuable opportunity for the orbiting Cassini spacecraft to observe brief adjustments in the rings which could reveal important clues regarding their intriguingly mysterious nature.

NASA’s Cassini spacecraft entered orbit around Saturn on July 1, 2004, and started to shoot some very revealing pictures of this gorgeous planet, its rings, and its plethora moons. Although Saturn seems to be a calm, tranquil world when it’s observed from a fantastic distance, the up close and personal observations derived from the Cassini probe revealed how deceptive distant looks can be. Actually, Cassini successfully was able to picture the Great Springtime Storm that shook up Saturn in early 2011. The whirling, swirling tempest was reported by NASA on October 25, 2012, and this mad storm displayed an enormous cloud cover as big as our whole planet!

Saturn is tilted on its axis–just enjoy our own planet. Over the long passage of its 29-year-long orbit, our Sun’s vibrant and illuminating rays of light travel from north to south across the gas-giant and its bands, and back again. The changing sunlight causes the temperature of the rings–which are composed of trillions of glittering, frozen bits of somersaulting ice–to change from 1 season to the next. During the equinox, which lasts for only a couple of days, strange and weird shadows and wavy constructions seemed and, as they lingered from the distant twilight of this faraway world, the rings began to cool.

In a study published in the planetary science journal Icarus, the group of Cassini scientists noted that one element of the rings seems to get warmed up throughout the Saturnian equinox. This slightly toasty temperature supplied a one-of-a-kind peek through a window of opportunity into the secretive interior arrangement of ring particles not usually readily available to interested astronomers.

Bands and Icy Matters

In 1610, the great Italian astronomer Galileo Galilei turned his crude telescope to the starlit skies, and became the very first person to see the rings of Saturn. Although reflection from the rings raises Saturn’s brightness, they can’t be observed from Earth with the unaided human eye, and Galileo wasn’t able to see them well enough to discern their true nature. Galileo wrote to the Duke of Tuscany that “[T]he planet Saturn isn’t alone, but consists of three, which almost touch one another and never move nor change with respect to one another. Galileo went on to explain Saturn as possessing “ears”. The bewildered Galileo wondered, “has Saturn swallowed its kids?” , speaking to an early Greek and Roman myth by which Saturn (Greek, Cronus) devoured his own children to prevent them from overthrowing him. But, then, the mysterious architecture reappeared in 1613, further confusing Galileo.

In 1655, the Dutch mathematician and astronomer, Christiaan Huygens, became the first person to describe this mysterious arrangement as a disk encircling Saturn, and he did this using a defracting telescope that he had designed himself. This early telescope was really superior to that which Galileo had utilized, and Huygens was able to watch Saturn. Huygens noted that “It [Saturn] is surrounded with a thin, horizontal, ring, nowhere touching, inclined to the ecliptic.” The British scientist Robert Hooke was also an early observer of the Saturnian rings.

In 1787, The French scientist Pierre-Simon Laplace suggested that the rings were made up of a large number of solid ringlets, and in 1659, the British astronomer James Clerk Maxwell calculated that the rings could not possibly be solid since, if they had been, they would become unstable and fall apart. He then proposed that Saturn’s rings have to be composed of a profusion of small particles–all independently circling Saturn.

The rings form a very thin, broad, and scenic expanse that is roughly 250,000 kilometers across–but less than tens of hundreds of meters thick. Historically, the age and origin of Saturn’s rings are difficult for astronomers to determine, some stating they are very youthful structures, and many others stating they are actually primordial structures–as old as our 4.56 billion year old Solar System.

The icy fragments which compose Saturn’s glorious system of rings vary in size from frigid smoke-sized particles to boulders as large as some skyscrapers. These frozen, tiny, swirling objects jitter-bug around together in a distant dance around the world, interacting with one another, and twirling around together. The freezing ring fragments can also be influenced by their planet’s magnetosophere.

Saturn’s rings are named alphabetically according to the sequence they had been detected. There are several fainter rings which were found more recently.The D ring would be the one closest to its planet, and it’s extremely faint. The slim F ring is located just out of this A ring, and beyond which are a duo of considerably fainter rings dubbed G and E. The rings exhibit a good deal of structure on all scales, and some are influenced by perturbations due to Saturn’s moons. However, much still remains to be explained.

Data derived from the Cassini space research demonstrate that the Saturnian rings have their own setting independent of the of the planet. The air is made up of molecular oxygen gas which forms when ultraviolet light from our Star interacts with the water ice of their rings. Chemical reactions which occur involving water molecule fragments and additional ultraviolet interactions kind, and then toss out, oxygen gasoline–among other items. This ring setting, despite being very thin, was spotted from Earth from the Hubble Space Telescope. The rings themselves have a whole mass which amounts to only a small fraction of their whole mass of Saturn, and is just a bit less compared to the icy, mid-sized Saturnian moon Mimas.

Saturn’s Unusual Young Ring

“For the most part, we can not find out much about what Saturn’s ring particles are like deeper than 1 millimeter below the surface. But the fact that one part of the rings did not cool as anticipated allowed us to mimic what they are like on the inside,” explained Dr. Ryuji Morishima in a September 2, 2015 NASA Jet Propulsion Laboratory (JPL) Press Release. Dr. Morishima of this JPL in Pasadena, California, headed the study.

The astronomers carefully scrutinized data gathered from Cassini’s Composite Infrared Spectrometer through the year around equinox. The tool obtained valuable information regarding the temperature of the rings as they cooled. The scientists then compared the temperature data with supercomputer versions that was designed to describe the properties of this ring particles onto a single scale.

What the scientists found was a mystery. For the majority of the tremendous expanse of Saturn’s rings, the computer models correctly predicted just how the rings could cool off as they descended into the cold, mysterious darkness. However, one rather large segment–the outermost of the large, main rings, dubbed the A ring–has been considerably more balmy than versions predicted. The temperature spike was particularly intense in the middle of this A ring.

To be able to address the bewitching, bewildering, and bothersome puzzle, Dr. Morishima and his group conducted a detailed study of exactly the ring particles with varying constructions would warm up and then cool down throughout the departure of Saturnian seasons. Earlier research based on data derived from Cassini have shown that Saturn’s icy ring particles have fluffy exteriors, which are like fresh snow. This outer, fluffy, snowy coating–termed regolith–forms over the passing of time, as tiny impacts crush the surface of each frozen, icy particle. The team’s analysis indicates that the best explanation for its A ring strange equinox temperatures would be for the ring to be made up primarily of particles about 3 ft broad composed mostly of solid ice, with only a very thin coating of sterile regolith.

“A high concentration of dense, solid ice balls in this 1 area of Saturn’s rings is unexpected. Ring particles usually spread out and become evenly distributed over a timescale of roughly 100 million years,” Dr. Morishima mentioned from the September 2, 2015 JPL Press Release.

The piling up of dense ring particles in 1 region implies that some process either transferred the particles there in the recent geologic past or the particles happen to be confined there, for some undetermined reason. The astronomers suggest some possibilities to explain how this accumulation happened. A moon might have once danced around at the place within approximately the last hundred million years, but it had been doomed to destruction–maybe it was the luckless victim of a giant, catastrophic smash-up with a different object. If this really happened, debris in the effect might not have had adequate time to spread evenly through the ring. Alternatively, the astronomers suggest that tiny, rubble-pile moonlets–whose component fragments are only loosely held together by gravity to form what looks like one thing–could be carrying the frozen, dense particles since they wander around within the ring. The moonlets could disperse the icy fragments in the middle A ring because they disintegrate there under the merciless gravitational influence of Saturn and its larger moons.

Cassini project scientist, Dr. Linda Spilker of this JPL, and a co-author of this research, told the press on September 2, 2015 who “This particular result is fascinating since it implies that the middle of Saturn’s A ring might be a lot younger than the rest of the rings. Other parts of the rings might be as old as Saturn itself.

During its final close orbits around Saturn, Cassini will measure the mass of their gas-giant’s rings for the first time, using gravity science. Astronomers will subsequently use the mass of their rings to place constraints on their actual age.
