What is Solar Wind?

Solar wind is a stream of charged particles from the sun, or is called

The sun is a high-temperature gas sphere (strictly speaking, a plasma sphere), which can be divided into three layers. What you usually see with the naked eye is the "photosphere layer", and the "photosphere layer" is on the photosphere layer. Outside is "

Although the solar wind is violent, most of it will not hit the earth. This is because the earth has its own umbrella, the earth's magnetic field.

Astronomers have found one of two types of solar wind, according to NASA Space Network

A house whose windows have been blown by the wind, although it is generally resistant to violent storms, but the wind that breaks through the windows can make the house mess. The latest research shows that the earth s magnetic field is like a house that is easy to leak in front of the solar wind. Its holes will continue to wind through for hours, allowing charged particles from the sun to enter the earth s atmosphere, disrupting communication and power systems. And so on.

In 2012, the strongest solar storm in five years erupted on the morning of March 7th, and it was directly affected by wireless communication. After more than 30 hours of space travel, a large number of protons reached the outer layer of the Earth's atmosphere at about 8 pm on the 8th. Experts say this

August 2010

Severe solar storms on the surface of the sun have been observed by observatories in various countries. Scientists predict that the solar wind carrying a large number of charged particles will reach the earth on August 3, 2010, producing strong aurora phenomena at the poles.

On March 13-14, 1989, a solar storm hit a power station in Quebec, Canada, and the voltage burner caused power outages in the region. Many near-Earth satellites and geosynchronous orbit satellites were abnormal, orbitally changed, and even scrapped. Global radio communications were disrupted or Interruption, failure of navigation systems of ships and aircrafts: One communication satellite in Japan is abnormal, one orbiting satellite in the United States is down, four navigation satellites of the U.S. Navy are shut down one year in advance, and more than 6,000 tracking targets have been lost; astronauts and high-altitude aircraft Passengers received doses in excess of police.

On April 29, 1991, a severe magnetic storm caused catastrophic damage to a nuclear power plant in Maine, United States.

On January 20-21, 1994, two Canadian communications satellites failed.

January 6-11, 1997

At first, people thought that the solar wind might exist based on the phenomenon that the comet's "tail" (comet tail) always turned away from the sun. In the early 1960s, observations of satellites and spacecraft proved the existence of solar wind. Space observations in the 1970s found that there were strips or massive local dark areas on the X-ray corona photos, called coronal holes. Coronal holes are areas where the radiation and brightness of the corona are much weaker than the surroundings. It reflects the uneven distribution of the corona material.

The speed of the solar wind near Earth's orbit is generally about 450 km / s, while the speed of the solar wind from the coronal hole is much faster, about 1000 km / s. The solar wind can blow far, beyond Pluto, the farthest planet in the solar system, and into vast interstellar space. ^[4]
