The Sun is a giant nuclear reactor the size of a million Earths.
This is a giant cauldron, decimated violent atoms and occasionally has a bit of bad weather.
On Monday, the time has arrived in splendid style as millions of tons of superheated material was propelled into space in a spectacular event known as a solar flare.
Here on earth who does not feel anything - is relatively low and the explosion was not aimed directly at us. If you live in the far north you can see the aurora borealis in the sky as the growing number of high-energy particles to break the Earth's magnetic field.
The largest solar flare in recent history is known as the Carrington flare. On September 1, 1859, English astronomer Richard Carrington observed a series of flashes in a group of dark areas on the Sun's surface known as sunspots.
The sky darkens London was bathed in a spectacular display of northern lights, which are rarely seen in southern Britain. It said you could read a newspaper by its light.
But there is a far more threatening side. In 1859, the telegraph network as a whole is not as powerful electric current transmitted by the son. Operators of electric shocks and burned papers.
If a rocket fired Carrington size today, we believe that a large number of satellites in orbit may be permanently damaged, leading to a communications failure and the potential chaos.
Fortunately, these explosions occur only once every 500 years, but few signs of this week is a reminder of the power of our nearest star, friendly but menacing.
