Saturn in the lens
• Saturn in the lens
This mysterious planet is the second largest in the solar system, second only to Jupiter. Here, the average surface temperature of minus 180 ° C, and the wind speed reaches places 1,800 km / h. Saturn has more than 150 satellites and the most spectacular system of rings.
Today's look with the automatic interplanetary station Cassini, which is designed to study the planet Saturn, its rings and satellites.

The Cassini spacecraft has made a unique picture in which we can see the giant system of rings, the circumpolar vortex and the mysterious hexagon storm. The photograph was taken at a distance of the order of 2 200 000 km from the object, image resolution is 131 km per pixel.
A giant hexagon on Saturn's north pole, which could accommodate 4 Earth is still a mystery to us. It was first discovered by scientists in the 1980s. Each side of the hexagon has a length of about 13 900 km, and the period of rotation - 10 PM of the 39 minutes. (Photo by Nasa | JPL-Caltech | Space Science Institute):
The monstrous storm, covering the north pole of Saturn. The picture shows the eye of the hurricane is visible diameter of about 2000 km. Thin and bright clouds at the outer edge of the hurricane, moving at a speed of 150 m / s. The main difference from the Saturnian storm terrestrial counterparts - the huge size and amazingly high speed. (Photo by Nasa | JPL-Caltech | Space Science Institute):
Very fresh snapshot. Dazzling rings of Saturn with ice fragments, January 30, 2017. In 1921, a rumor spread that the Saturn lost its rings, and its particles move in including the Earth. Anticipated event so excited the minds of people that were published calculations, when the Earth will fall ring particles. The rumor came from the fact that the rings are simply turned edge-on to Earth observers, and since they are very thin, the instruments of the time they can not be seen. People understood "the disappearance of the Rings" in the literal sense, and that gave rise to the rumor. (Photo: NASA | JPL-Caltech | Space Science Institute):
A rare picture of three satellites of Saturn at the same time. The largest of the three - Tethys (1,062 km across). The second largest is - Hyperion - a natural satellite of Saturn (270 km in diameter). Hyperion density is so low that it is likely to consist of 60% of a conventional water ice with small amounts of stones and metals as the main part of its internal volume (up to 40 percent or even more) constitute voids. Tiny Prometheus (86 km in diameter) - moon, who is called the "shepherd" F. The rings (Photo Nasa | JPL-Caltech | Space Science Institute):
Enceladus - the sixth largest moon of Saturn. It consists primarily of water and ice is almost white surface with the record in the solar system cleanliness and reflectivity. (Photo by Nasa | JPL-Caltech | Space Science Institute):
Cassini station is found on Saturn's moon Enceladus snowman, which form three of the crater. Pictures received October 14, 2015, when the machine is at a distance of 1839 kilometers from the surface. (Photo by Nasa | JPL-Caltech | Space Science Institute):

In 2014 were published the results of studies, according to which there is a subsurface Enceladus ocean. The basis of this finding formed measurements of the gravitational field of the satellite, made during three close (less than 500 km above the surface) spans "Cassini" above Enceladus 2010-2012. The data allowed the scientists are confident enough to say that under the south pole of the satellite lies an ocean of liquid water. (Photo by Nasa | JPL-Caltech | Space Science Institute):
Two of Saturn - Dione (next) and Enceladus (more). Dione consists mainly of water ice with a large stone impurity species in the inner layers. (Photo by Nasa | JPL-Caltech | Space Science Institute):
A giant moon Titan. Saturn largest, the second largest satellite in the solar system (after Jupiter Ganymede satellite), is the only other earth body in the solar system, for which proved stable existence on the surface of the liquid, and the only companion planet having a dense atmosphere.
The pressure at the surface is about 1, 5 times the pressure of the earth's atmosphere. The temperature at the surface - minus 170-180 ° C. Cool. Titan's diameter - 5152 km, it is 50% larger than the Moon, while the Titan is 80% greater than the mass of the satellite on the Earth. (Photo by Nasa | JPL-Caltech | Space Science Institute):
The satellite Mimas in all its glory. With a size of about 400 kilometers, it is the twentieth-largest moon in the Solar System, as well as the smallest known cosmic body, which has a rounded shape due to its own gravity. (Photo by Nasa | JPL-Caltech | Space Science Institute):

Iapetus - the third-largest moon of Saturn and the twenty-fourth of the distance away from the 62 known his companions. Another unique feature of Iapetus - a series of mountain ranges and individual peaks, which stretches along the equator and is known as the Wall of Iapetus.

Phoebe - one of the remote irregular satellites of Saturn, W. Pickering opened in 1899 on photographs taken in Arekipskoy Observatory (Peru). Named in honor of Phoebe titanidy from Greek mythology. Phoebe is very dark body, but the interior of some craters composed of lighter material, presumably ice. (Photo by Nasa | JPL-Caltech | Space Science Institute):
The probe "Cassini" made "family portrait" of Saturn with its rings in all the Earth's environment, the Moon, Mars and Venus - NASA experts gathered this panorama of 141 wide-angle shots. The frame is put Venus, Mars and the Moon the Earth, they are seen as a weak Stars: bluish earth with a tiny spot near the moon, and yellowish white Venus Mars.
