More severe symptoms include fever, chills, and a jaundice. Jaundice is a condition where bile is backed up into the liver when gallstones block the cystic duct. This causes the bile to be forced into the bloodstream, where it will travel and cause your skin and the whites of your eyes to turn yellow.
The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.
When the nuclei get close enough, the force that binds protons and neutrons together, the strong force, takes over and pulls the nuclei even closer together. The sunâs core is a natural fusion reactor. Before the sun formed, it was a cloud of gas mostly made up of hydrogen and some helium. At some point, the cloud became so massive that gravity caused it to collapse in on itself and it formed a star.
