What is the Sun made of? Pierre Robitaille, the world's greatest spectroscopist, has a detailed and interesting answer. Liquid metallic hydrogen in a hexagonal planar form (very similar to the bonds between carbon atoms in graphite). This is why the solar spectrum is identical to the spectrum of a 'blackbody'. The Sun is a liquid, not a gas.
