Scientists wonder for decades what causes the solar wind. We were announced in December 2007 about Japan’s Hinode satellite orbiting earth, which offers an amazing view of the dynamics of the sun.

Earth’s magnetic field creates a bubble around which the solar wind must flow. But sometimes, strong gusts can disrupt power grids, satellites and communications systems on earth.

The sun’s secret has unveiled last week by Professor Louise Harra, a University College London researcher, at the Royal Astronomical Society meeting in Belfast.

He stated that phenomenon has been debated for many years, and that the process is violent, like most phenomena associated with stars. The images he showed were from Japan’s Hinode satellite. They showed magnetic fields linking two bright spots on the sun which are nearly 500 million km apart(the distance is equivalent to 40 earths- side by side).

The solar wind is a stream of electrically charged gas, mostly hydrogen, which flew out in all directions when the magnetic fields smash into each other. The wind blows outwards from the sun in all directions at a speed of about 1.6 million km/h.

Harra is full of enthusiasm because they have been finally able to locate exactly the source of the solar wind, adding that they try to figure out how the wind is transported through the solar system.

At this meeting from Belfast, astronomers spoke about volcanic-type explosions of gas from the sun’s atmosphere and the forces behind them.

These places of increased pressure, called fountains, are at the base of the sun’s magnetic fields. The pressure periodically decreases and allows the gases to fall back toward the sun’s surface.

They made computer simulations, using data from Hinode satellite, and discovered that any new section of magnetic filed which are constantly emerging across the whole of the solar surface, generates a continual cycle of fountains.
