Periodic Table of Elements
The periodic table is the "list of ingredients" for our entire universe. Most of the elements were formed in nuclear reactions, which took place inside stars or exploding stars called supernovas. Some of these nuclear reactions continue to take place inside our sun (shown in this X-ray photograph), which releases energy when the element hydrogen undergoes fusion and is converted to the element helium.
