Major storms that occurred in Saturn new record because it lasts up to 200 days or more than half a year. The storm was the biggest recorded over the past two decades is well recorded by the Cassini spacecraft of the formation, evolution, until gone.
Monitoring results show, the monster storm came on December 5, 2010 at the point of latitude 35 degrees north of Saturn. The storm then moved around Saturn enlarged first time in January 2011, extends to 15,000 kilometers from north to south before finally narrowed and then disappeared in June 2011.
Based on the records of NASA, the storm was recorded as the longest, beating the 1903 storm which lasted for five months. Coverage of the region affected by the storm reached 5 billion square kilometers or 10 times the Earth's surface area.
The velocity of the storm reaches 1756 km / hour. This is much faster than the fastest storms on Earth are only 66 km / hour. The storm is moving so fast it appears as colored mosaics that adorn the top of Saturn's equator.
In astronomy, the great storm known as White Spot of Saturn. This phenomenon tends to appear every 2-3 decades. This phenomenon has been detected also in 1990 by the Hubble Space Telescope, but it only lasted 55 days.
Andrew Ingersoll, a member of Cassini's imaging team at Caltech, Pasadena, said, "Storms of Saturn's more like a mountain fire than weather phenomena on the mainland. The pressure formed over many years before the storm bererupsi. Mystery is, no rocks that resist pressure to delay the eruption during many years. "
Another Cassini imaging team member, Kunio Sayanagi from Space.com quoted UCLA on Friday (11.18.2011), said, "The fact that the phenomenon takes place in a particular period and always occurs every 20 or 30 years says something about the inner planets it, but we do not know. "
Cassini orbiting Saturn since 2004, examined the rings and moons of Jupiter. Spacecraft will continue to orbit until 2017 it is estimated that there are many more surprises from jepretannya.
Cassini shots for storms that occurred in December 2010 to June 2011 can be seen in the picture above. The images on show in August 2011, although the storm had ended in June, the impact of white clouds can still be seen until later.
