Scientists prove that ' magnetic ropes that cause solar storms '

George Mason University scientists recently discovered that the phenomenon called magnetic giant rope is solar storms. Confirm the existence of this formation is a major step in helping to mitigate possible negative effects on the solar storm blasts teleport on Earth.

This discovery by Professor Zhang JI and Zheng Xin using images from spacecraft NASA Solar Dynamics Observatory (SDO) for graduate students.


Although these rebellions believed to be due to the magnetic Lasso the Sun giant was scientists previously had been unable to prove the existence of this phenomenon given how fast transfer cord.


However, Zhang was able through strict examination of images taken from telescope aerial imaging Assembly (AIA) aboard SDO, identify the Sun as a magnetic rope. AIA telescope Suite capable of taking pictures of the Sun every 10 seconds, 24 hours a day. This unprecedented rate at the time of discovery.


"Magnetic cord running solar energy explosion. Scientists have debated whether this magnetic Lasso before erupting solar energy. Zhang says that as a result of this observation, I think an excellent help to resolve this contentious issue, and finally ".


Solar storm of violence of the Sun, sending billions of tons of cargo, also called plasma, space quickly over 1 million miles per hour. Plasma cloud holds strong magnetic field. When deposited magnetic cloud reaches Earth one to three days, a large amount of energy in the Earth's magnetic field.


Usually the Earth's magnetic field protects these harmful solar winds and protect the environment. However, the potential of solar storm to disable shielding effect and produce severe space weather, which could adversely affect a wide variety of technological systems, including the operation of satellite and power systems, communications and navigation.


Zhang research will help to give early warning of solar storms and help reduce the damage caused by space weather here on Earth.


"Understanding the outbreak of these storms will help us better predict," says Zhang. "We cannot prevent solar storms, just as we cannot prevent earthquakes or volcanoes. But evolution forecasting capabilities can help to mitigate the negative effects. For example, satellite operators can power down regulations to prevent possible damage to key systems. "


It is widely believed that the Sun's magnetic fields play an essential role in energy storage and solar storms. However, the precise form that magnetic field lines before highly controversial outbursts. Most field lines loops ?????? with foot rooted on the surface of the Sun. Cannot be transformed easily, in fact, often playing the role of preventing the outbreak.


Scientists suspected that magnetic Lasso, if any, in fact, is the phenomenon which powered explosion. Magnetic rope contains many lines of the magnetic field around the Centre axis and may twist around each other. Due to distortion, electric current can be strong magnetic Lasso. In theory, could produce electricity electromagnetic force sufficient to overcome the strength of other items tied it in the field and the magnetic power cord to go abroad.


AIA now reveal pictures is long and low Canal passes through the energetic heats to temperatures up to 10 million degrees and rising slowly, before the outbreak,. When it reaches a critical point, and quickly begins to erupt. They feature different surrounding magnetic field lines. These special hot channel magnetic Lasso believed they were looking for scientists is now.


Chang is a professor in the Faculty of physics and astronomy and mathematical sciences, and worked with "space weather laboratory at George Mason University. And reported his results at the American Astronomical Society Solar Physics Division, held in Las Cruces, New Mexico on 12-16 June, 2011.
