At the final days of the Cassini mission, NASA's spaceship placed a series of orders for space circles around Saturn, which was the first unseen scratch of the gun's prison ring. The astronomers have now looked at these images and other images by showing a new light on these fascinating and pioneering Sunday's moments.

Saturn has a circle of around 60 known moonlight, a little inside or working closely with the planet's ring system. New research published today in Science gives some new information about five of these ring circles – Pan, Daphnis, Atlas, Pandora, and Epimetheus – including details of their shape and shape. T shape. The new paper, led by Bonnie Buratti from NASA's Jet Propulsion Laboratory and California Institute of Technology, is also giving a new insight into Saturn's space system and how it might create.

Cassini's six-ring ring has met between December 2016 and April 2017, with the mission finishing in September 2017 when the trial first dried to Saturn. Cassini's pictures were wonderful, displaying parallels with anything previously seen.

Gabh Pan, for example, a five-mile (8 km) moon with distinctive ditches on its surface and a bulky-sized drum-like ridge. Daphnis is seated in a secluded area within a gap in the Saturn ring, and is also surrounded by a “skirt”.

Indeed the five moons within this are none – none wider than about 12 miles (20 km) – very strange, appearing unconventional shapes, surface features, and colors. What is bigger, there seems to be a close relationship, but not a good understanding, of the Saturn rings. With new Cassini data and these intriguing, close-up images, Buratti and her colleagues were able to look more closely at these secret items.

“We were trying to find out how the ring rings and the main ring system are connected,” Buratti said to Gizmodo. “Largely, are they like one?”

Buratti and her colleagues were also looking for ideas that told if Saturn's rings were created after a poisonous accident, and if the enormous mass of material inside the circles judged it. ring rings. In fact, the rock and ice disc around Saturn could be the same, and be involved in similar processes to the disc-protoplanetary plane of the Sun (from which the planets include) t Earth, formed in early days of the sunshine. Finally, the researchers hoped to find out if these chemicals have variable chemicals as well as having a rainfall.

The unique geology of these five wheels, from analysis, evolved from a complex multi-stage process in which the objects are made from concealed concrete objects. The strong pressure of the tide caused the moldy rump of rings, the grooves and the ridges to create on the surface. So it appears that the hills and ring system are formed from one great effect.

“The talons left behind are huge lumps“, Buratti said to Gizmodo. “The parts of the skirts around the circles are items from the rings that are forwarding. The way in which the hills get out in their pathway may be a smaller example of how planets make out of smaller tiny pieces. ”

In terms of the strange colors, Pan is the favor when Epimetheus is most beautiful. Buratti said she was very surprised when the color was red in Pan, saying that the hills are rising as you approach Saturn, which suggests that their arms are rising. The chemicals that depend on the colors, and that the processes involved are not fully understood, but there may be red chromophores – a variety of growth- looms and iron. Ice or water particles from the E-Sat ring and Saturn's water vapor from the moon's volcanic volcano could be affected by paper.

“The survey confirms the impact of the watercolor pieces launched from the Enceladus roots throughout the Saturn system,” said Tracy Becker, planet scientist at the South West Research Institute. was involved in the new survey, Gizmodo. “It's interesting to see how these small fragments change the color and luxury of the fumes closest to Enceladus, and also fascinating to find out how good Saturn's rings protect the embedded parts of some of the t of these pieces. ”

Just like the variables apart from the ice, it was not found that they had squeezed the ring rings.

“By depicting molluscs with more evaluation of the ice, that seemed to come from a colder area outside the Saturnian system,” the authors wrote in the new survey. “For example, when CO2 ice was discovered on the irregular outer moon Poebe suggested that it had originated from the Kuiper Belt. ”

The absence of volatiles is therefore a further testimony to the fact that the ring rings formed within the rings were intact and were not drawn up by intense Saturn graffiti.

“The results of this paper help us to gain a better understanding of the complex cosmetic play at work in the Saturnian system,” said Tanya Harrison, an astronomer at Arizona State University who is not connected to the project. new survey, to Gizmodo. “The moorlands, ring rings, and even Saturn itself all interact to create a world and environments that are nowhere else in Solar Supply.” T

The best part of the study, Harrison, said that the amazing players had found-Pan-Daphnis and Atlas – as they picked up ice fragments and dust from Saturn's rings around their media when they moved. in their coast. For her favorite moonlight, that difference goes to Pan.

“I want to find out what it is like to be at the bottom of the belt and to look at it,” she said, “He is looking very tricky, so I think he is a bit like the Wall. Game Thrones. ”

Like Harrison, Pan, particularly distinguished by Becker, is especially marked by the differences seen on his equator. She wants to know why the thickness and width of the lock are so variable around his surface. Becker said future research should look at and show how and where the ring circles are gathering on the moon surface.

Another interesting idea (though not entirely surprising), Harrison said that the moon is closer to Enceladus, the tweed that is – which could lead to the draining of water and the smoke from a shingle horse south of Enceladus'.

“That stuff makes up the whole Ringtone of Saturn and spores down on nearby moors,” Harrison said to Gizmodo. “Enceladus is making a big mess, albeit beautiful, over the Saturnian system. ”

Also, the new paper is important in the way that Saturn's circles can be used as a proxy for the discs around young stars where the planets are made – including the beginning of the Solar own plant.

“Obtaining the images and measurements of the satellites that are embedded within the circle is one of the best ways to learn about how planets do, grow, and interacting with the disc, ”said Becker.

Saturn is, of course, one of the most interesting and intriguing aspects of the entire solar system. It includes worlds within the world, and as a result of old friend Cassini, we are lucky enough to be able to find these places.
