The sixth planet from the Sun and the second-largest in the Solar System was the most distant of known planets to ancient civilizations. The gas giant appears to us in a pale yellow color because of its upper atmosphere contains ammonia crystals. It is made up of 94% hydrogen, 6% helium and small amounts of methane and ammonia. Hydrogen and helium are what most stars are made of. It is thought that there might be a molten, rocky core about the size of Earth deep within Saturn. Its ring system, extending hundreds of thousands of kilometers from the planet, is the most complex one in our Solar System. First observed in 1610, by the Italian astronomer Galileo Galilei. What he saw through his telescope he described as separate spheres. Saturn appeared to Galileo to be triple-bodied. In 1659, the Dutch astronomer Christiaan Huygens, using a more advanced telescope suggested that Saturn was surrounded by a thin, flat ring. He had the resolution to realize that the Galileo's 'separate spheres' on the sides of Saturn were actually rings: “a thin, flat ring, nowhere touching, and inclined to the ecliptic.” In the 1980s, NASA's Voyager spacecraft revealed us that Saturn's rings are made mostly of water ice. Hubble Space Telescope images show, that Saturn's polar regions have Aurorae similar to Earth's. Four Saturn Days. Video/Images: NASA's Cassini spacecraft stared at Saturn for nearly 44 hours in April 2016 to obtain this film showing four Saturn days. Cassini began a series of dives between the planet and its rings in April 2017, building toward a dramatic end of mission -- a final plunge into the planet, six months later. Sound: Cassini has been detecting intense radio emissions from the planet Saturn. They come from the planet's Auroras, where magnetic field lines thread the polar regions. The radio emissions can be captured by the specially designed instrument known as 'astronomical interferometer'. This device can convert the radio waves into the frequency within the range of human hearing (20 - 20,000 Hz). Interesting Facts about Saturn: Saturn - sometimes called 'The Jewel of the Solar System' is a giant gas planet. It is named after the Roman god Saturnus. Saturn was known to the ancient Greeks as Cronus. Saturn’s distance from the Sun is 1.4 billion km. A year on Saturn is more than 29 Earth years. A day on Saturn is 10 hours and 14 minutes. The interior of Saturn is scorching hot, reaching temperatures of up to 11,700°C. Saturn's rings are less than a kilometer thick. Saturn is the least dense planet in the Solar System. It is the second largest planet in our Solar System. Jupiter is the only planet that is bigger. Saturn has oval-shaped storms similar to Jupiter’s. Christiaan Huygens was also the first one to discover Saturn’s largest moon - Titan. Saturn's largest satellite, Titan, is bigger than the planet Mercury. Saturn has 82 known moons, or moons, and there are probably many more to be discovered in the future. Saturn gives off more energy than it receives from the Sun. Winds around the Saturn's equator can be 1,800 kilometers per hour. Just to compare - on Earth, the most powerful winds get to about 400 km. per hour. Saturn has been visited 4 times by various spacecrafts: The Pioneer 11, in 1979, the Voyager 1 in 1980, the Voyager 2 in 1981 and Cassini’s - in 2004, which actually went to orbit Saturn capturing photographs of the planet, its rings and moons. Other planets have rings too, but the Saturn's rings are the only ones that can be seen from our home planet. All you need is a simple telescope. Saturn can be seen with the naked eye. The distance to Saturn from Earth is constantly changing as both planets travel through space. When the two are closest, they lie approx. 1.2 billion km. apart, or eight times the distance between the Earth and the sun. Saturn is about 1.3 light hours away from the Sun. The day Saturday was named after Saturn. ☕️ https://www.buymeacoffee.com/stadst For more information about the Cassini-Huygens mission visit http://saturn.jpl.nasa.gov/ and http://www.nasa.gov/cassini. #soundofsaturn #nasa #soundsofplanets #isro #alien #alien
