The Saturn


This is the second biggest in our solar system and the only planet whose average mass does not exceed that of water so if there is a sea that surround Saturn could soar.
At Saturn from a modern telescope in 1610, Galileo draw it as a globe bounded by two smaller ones as a head with large ears (the first one who came up with the Mickey Mouse logo). Galileo thought it was moons but when two years later reviewed the planet had disappeared. Later in 1655 the Dutch astronomer Christian Huygens discovered Saturn having had a satellite orbiting Titan, announced that the planet should be surrounded by an equatorial ring.

The history of the solar storm


A geomagnetic storm turn off the electricity grid in most of Quebec,in march 1989.At that time,  millions of Canadians was leaving without power for hours.In March 1989,The NASA reports,in January 1994 the communications satellite 290 million Anik E2   Canada, was shat down by a solar storm, and took six  months and $ 50-70 million put back into operation.One of the most dangerous contributors to solar storms is a coronal mass ejection (CME), a great cloud of charged particles belched from the sun and sailing through space at supersonic speeds.

Storms are classified in various intensities


The Solar Wind, which had an average speed of 500 km / sec, reached in the three days following a speed of more than 50,000 km / sec. From there began to descend to 33,000 km / sec, speed was maintained for 30 days. Although this seemed impossible, what happened?
The event was mentioned in all the magazines in the world, and in major newspapers, but scientists did not know what it was. All they did was to publish the data at their disposal. In 1989, a class X19 solar flare, issued a radioactive storm hit Earth and knocked out the Hydro-Quebec power grid for several hours, to merge several generators.
