The Sun is the superpower of our Solar System, a thermonuclear blast furnace, erupting with massive explosions. It can be the same amount of mass as mount Everest coming out from the Sun and flying out into space. At 93 million miles away it would seem that we are safe from the Sun's wrath. But, are we? It matters, especially in modern times, what the Sun is doing. From the center of the Sun, as it rotates around, is the "kill zone". With some experts predicting the most violent outbreak of solar activity in modern history. it’s never been more important to understand the secrets of the Sun. There are billions of stars in the Universe but one alone dominates our cosmic neighborhood: the Sun. It's an infernal sphere, of mostly hydrogen and helium, superheated into a plasma, that burns at millions of degrees. Its surface reages with violent explosions, as it spews out storms of deadly radiation, millions of miles into space. Our Sun is a type of star known as a yellow dwarf. Yellow because of the colour of its surface, and dwarf because it's small for a star. But small is relative. Within its boundaries, you could fit one million earths. In our Solar System, there's simply no bigger star than the Sun.
