The sun; located in the centre stage of our star system, humbly start its lifetime inside relatively dense concentrations of interstellar gas and dust known as molecular clouds.
As the material drew together, gravity caused it to spin. The spin caused the cloud to flatten into an accretional disk. In the center, the material clumped together to form a protostar which is a ball of hydrogen and helium not yet powered by fusion.
As the pressure and temperature increases (>10 million kelvin!), hydrogen starts to fusion and eventually drives the sun that we know today.
A little announcement. Starting from this week, we will publish one new page on both Saturday and Sunday. Stay tune!
