THE SUN AND ITS STRUCTURE

The sun is the only star that allows life on the Earth.

The CORONa is the outer most part of the Sun made up of very thin oinized gas , its temperature can reach 1 million Kelvin. The solar winds are currents that can reach high speeds THAT GO from 250 to 800 km/s into inter stellar space and interacts with the solar system, for example the bombing of lunar rocks and the changing of their appearance.

THE SOLAR CORONA

SOLAR FAULTSWe call solar faults defects that we can see on the solar surface.

THESOLAR PROMINENCE

A prominence is a large, bright feature extending outward from the Sun's surface,

often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere,

and extend outwards into the Sun's corona.

THE SOLAR FLARES The solar flares

are the most explosive events in partnership to the sunspots. They last around an hour.The free enermous quantities of energy.

The mosts spectacular effects of the solar flares are the polar aurora. They are visible in proximity of the magnetic poles and you call northern auroras and southern auroras.
