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.
The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form the sun.
