Scientists devise new methods of observation, "see through" the sun.
<P Align=center> </ P> <P> latest news, according to Space News, NASA scientists have recently observed use of sunlight back to the spaceship according to a series of experimental observations, they found the experiment a .can be directly observed by the other side of the sun very long-range regional approach. .Previously, observations of this region can not achieve by traditional means. .</ P> <P> scientists at Stanford University in California Phil Siqie Siegel (sound), said, "application of this method can improve our understanding of solar magnetic storms forecast accuracy. When the storm the other side of the phenomenon of the sun .distance brewing, we will be able to find it, and take the appropriate measures to reduce storm moved to the direction of our planet caused by damage, protect the space station or the work is on track to run or the safety of astronauts. "</ P .> <P> intense storms is a manifestation of solar activity, which can fire a strong rays of the normal work of satellite and radio communications and other systems on the planet's operation. .Advanced warning systems can help us to stop the storms in the region of satellite and other systems work to the impact from the storm caused the paralysis of the system. .The sun's rotation period is 27 days, looking over the direction from the Earth, sun storms formed the other side of the phenomenon had been predicted has not succeeded. .</ P> <P> storm the sun will be the formation of sunspots under normal circumstances, it is the energy of the sun's surface magnetic field strong point. .Through this a new technology, we can see the sun on the back of what is happening, for the accurate prediction of geomagnetic storms has a huge boost. .</ P> <P> observation that a new technology is based on SOHO's Mai Kele Doppler imaging principle, through the acoustic response of the direct sun on the back of the observation area. .Around the sun has many one way or another the existence of sound waves, which are mainly due to the solar surface layer produced by gas convection. .This new technology by tracking the origin of these sound waves to speculate in the case of the other side of the sun. .</ P> <P> we can easily find the area of sunspot activity is frequent because these areas of magnetic energy is very strong, so that these areas faster running speed of sound waves. .And from the sun and the sun on the back of the front running speed of sound is not the same, scientists have determined that it is based on the origin location in the sound. .</ P> <P> Siqie Siegel explained that "the traditional long-distance imaging can only let us see the sun on the back of the center of the region, it is only a quarter of the sun back to a third of the entire region. .and this new technology allows us to see the sun but the back of all of the area. We have already began to use this new technology, hoping to create a full view of the remote imaging system, since 1996, according to observations from the sun back .spacecraft re-analysis of data collected. If we apply this new technology, analysis of these data is completed, we will be vast regions of the sun on the back of a more in-depth and detailed understanding of the region to enhance our study of the reliability level. ."</ P> </ p>.
