A celestial wonder, the Sun is a massive star that formed from a massive gravitational collapse when space dust and gas from a nebula collided, forming into an orb that is 100 times bigger and weighs over 300,000 times that of planet Earth. Made up of 70 per cent hydrogen and about 28 per cent helium (plus other gases), the Sun is the centre of our solar system and the largest celestial body anywhere near us.

“The surface of the Sun is a dense layer of plasma at a temperature of 5,800 degrees kelvin that is continually in motion through the action of convective motions driven by heating from below,” says David Alexander, a professor of physics and astronomy at Rice University. “These convective motions show up as a distribution of what are called granulation cells about 1,000km across and which appear across the whole solar surface.”
