The interior of the Sun has a density and temperature such thermonuclear reactions that occur, releasing enormous amounts of energy. Much of this energy is released into space as electromagnetic radiation, mainly in the form of visible light. But also the Sun emits a stream of charged particles, called the solar wind. This solar wind interacts strongly with the magnetosphere of planets and helps clean interplanetary space by ejecting gas and dust outside the solar system. This pot makes its energy by nuclear fusion through the enormous pressure and temperature that exist in her heart. If a gas is heated sufficiently, the electrons are detached from atoms and move freely, the matter no longer behaves like a gas and gives him the name plasma. Solar flares send continuously high energy particles in space and time to time, a bubble of plasma superheated and radioactive reaches the Earth. From time to time, coronal mass ejections (CME) propel a huge amount of matter in the direction of the Earth. Observational data of the users of Internet performed for the Solar Stormwatch and STEREO mission, have enabled to modeled solar storms in this explicit animation. Amy Skelt student at the University of Reading, wrote a program to enable us see this analysis in this explicit video. It shows the characteristics of mass ejections and solar wind activity during the first three years of the STEREO mission from 1 April 2007 to 31 March 2010.
nota: Table of maximum activity solar cycles.
The coronal mass ejections (CME) seems to vary from maximum to another within an average cycle of 11.2 years, but the duration can vary between 8 and 15 years. The Sun constantly produces 380 billion billion megawatts, 3.826 × 1026 W and that for billions of years. The most spectacular manifestations in a period of intense magnetic activity, are the appearance of sunspots and prominences. The number of spots increases progressively during the 11-year cycle.<:p>
Video: Observational data of the Internet users performed for the Solar Stormwatch and STEREO mission, have enabled modeled solar storms in this explicit animation. The flow of plasma of the solar wind bursts into space as gigantic bubbles by touching moment some planets in line with the ejection and especially the Earth. Sun ejects not only photons but also protons and electrons extremely energetic that constitute solar wind. This wind emerges from superficial layers and propagates in space. Earth is not completely sheltered by his screen magnetic, solar wind at a speed of 400 km/s, seeping through cracks polar to show us beautiful northern and southern lights, gleams with white, green and red.
