This was based on Five Elements which were traditionally used to classify natural elements. [155][156], Cassini photographs have revealed a previously undiscovered planetary ring, outside the brighter main rings of Saturn and inside the G and E rings. [86][87][88], An apparent oddity for Saturn is that it does not have any known trojan asteroids. Saturn was never habitable all the time. The moon Phoebe creates one of Saturn’s rings, and Iapetus is flying through its debris. Titan, Saturn's largest moon, and the second-largest in the Solar System, is larger than the planet Mercury, although less massive, and is the only moon in the Solar System to have a substantial atmosphere. Unfortunately, during the flyby, the probe's turnable camera platform stuck for a couple of days and some planned imaging was lost. [131] In Hindu astrology, there are nine astrological objects, known as Navagrahas. Jupiter's thermal energy is generated by the Kelvin–Helmholtz mechanism of slow gravitational compression, but such a process alone may not be sufficient to explain heat production for Saturn, because it is less massive. “Headed forward, you get all the bug splats,” Spilker said. [160] In April 2013 Cassini sent back images of a hurricane at the planet's north pole 20 times larger than those found on Earth, with winds faster than 530 km/h (330 mph). Phillips Davis The Voyager and Pioneer flybys of the 1970s and 1980s provided rough sketches of Saturn’s moons. [148], Pioneer 11 made the first flyby of Saturn in September 1979, when it passed within 20,000 km of the planet's cloud tops. In 1990, the Hubble Space Telescope imaged an enormous white cloud near Saturn's equator that was not present during the Voyager encounters, and in 1994 another smaller storm was observed. ... beyond the inner limit of the sun's habitable … The average distance between Saturn and the Sun is over 1.4 billion kilometers (9 AU). [82], A precise value for the rotation period of the interior remains elusive. The outermost layer spans 1,000 km and consists of gas. This photochemical cycle is modulated by Saturn's annual seasonal cycle. [26] The outer atmosphere is generally bland and lacking in contrast, although long-lived features can appear. [74] When Voyager 2 entered the magnetosphere, the solar wind pressure was high and the magnetosphere extended only 19 Saturn radii, or 1.1 million km (712,000 mi),[75] although it enlarged within several hours, and remained so for about three days. [58] Whereas temperatures on Saturn are normally −185 °C, temperatures on the vortex often reach as high as −122 °C, suspected to be the warmest spot on Saturn. [101][102], On 6 June 2013, scientists at the IAA-CSIC reported the detection of polycyclic aromatic hydrocarbons in the upper atmosphere of Titan, a possible precursor for life. Its intelligence or beneficial spirit is 'Agȋȇl (Hebrew: אגיאל‎‎, romanized: ʿAgyal),[136] and its darker spirit (demon) is Zȃzȇl (Hebrew: זאזל‎, romanized: Zazl). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally a gaseous outer layer. [103] On 23 June 2014, NASA claimed to have strong evidence that nitrogen in the atmosphere of Titan came from materials in the Oort cloud, associated with comets, and not from the materials that formed Saturn in earlier times. As scientists continue to analyze Cassini’s data, they will likely solve more mysteries about Saturn’s menagerie of moons, and they will almost certainly find more mysteries that need solving. The effect is more than just a cool visual. Our solar system’s habitable zone. The water vapor emitted into Saturn's orbit by this activity becomes charged and creates a drag upon Saturn's magnetic field, slowing its rotation slightly relative to the rotation of the planet. More close-up images of Saturn's moons were acquired, as well as evidence of changes in the atmosphere and the rings. Its strength at the equator – 0.2 gauss (20 µT) – is approximately one twentieth of that of the field around Jupiter and slightly weaker than Earth's magnetic field. That would result in the Earth spending part of each year outside the habitable zone, the ring around the sun where temperatures are right for liquid water. [18] Most of the magnitude variation is due to the inclination of the ring system relative to the Sun and Earth. Made of a pair of two-wheeled vehicles, DuAxel is designed to descend craters and near-vertical cliffs on the Moon, Mars, and beyond. [98] Traditionally, most of Saturn's moons have been named after Titans of Greek mythology. Titan: first global map uncovers secrets of a potentially habitable moon of Saturn Menu Close [76] Most probably, the magnetic field is generated similarly to that of Jupiter – by currents in the liquid metallic-hydrogen layer called a metallic-hydrogen dynamo. [93] Saturn's second-largest moon, Rhea, may have a tenuous ring system of its own,[94] along with a tenuous atmosphere. “It’s curious. Saturn also appears brighter when the rings are angled such that they are more visible. [42][43] These descending droplets may have accumulated into a helium shell surrounding the core. The conditions of habitability for natural satellites are similar to those of planetary habitability. Hyperion is the only object in the solar system other than Earth’s moon that’s been confirmed as having a charged surface. [129][131] Ancient Chinese and Japanese culture designated the planet Saturn as the "earth star" (土星). Water ice clouds begin at a level where the pressure is about 2.5 bar and extend down to 9.5 bar, where temperatures range from 185–270 K. Intermixed in this layer is a band of ammonium hydrosulfide ice, lying in the pressure range 3–6 bar with temperatures of 190–235 K. Finally, the lower layers, where pressures are between 10–20 bar and temperatures are 270–330 K, contains a region of water droplets with ammonia in aqueous solution. [167], From time to time, Saturn is occulted by the Moon (that is, the Moon covers up Saturn in the sky). NASA Official: [51] Ultraviolet radiation from the Sun causes methane photolysis in the upper atmosphere, leading to a series of hydrocarbon chemical reactions with the resulting products being carried downward by eddies and diffusion. [48][49][50] The upper clouds are composed of ammonia crystals, while the lower level clouds appear to consist of either ammonium hydrosulfide (NH4SH) or water. Observations of its gravity and the contents of the plume suggested that Enceladus almost certainly contains a subsurface liquid water ocean near its southern polar region. The total mass of these heavier elements is estimated to be 19–31 times the mass of the Earth, with a significant fraction located in Saturn's core region. Most people will require an optical aid (very large binoculars or a small telescope) that magnifies at least 30 times to achieve an image of Saturn's rings in which clear resolution is present. [26] Saturn's magnetosphere, like Earth's, produces aurorae.[77]. [153] In May 2011, NASA scientists reported that Enceladus "is emerging as the most habitable spot beyond Earth in the Solar System for life as we know it". A Saturnian opposition occurs every year—approximately every 378 days—and results in the planet appearing at its brightest.
