      A version of the periodic table of the elements color-coded with where   
      each element is thought to have originated. Please see the explanation

      Explanation: The hydrogen in your body, present in every molecule of   
      water, came from the Big Bang. There are no other appreciable sources   
      of hydrogen in the universe. The carbon in your body was made by   
      nuclear fusion in the interior of stars, as was the oxygen. Much of the   
      iron in your body was made during supernovas of stars that occurred   
      long ago and far away. The gold in your jewelry was likely made from   
      neutron stars during collisions that may have been visible as   
      short-duration gamma-ray bursts or gravitational wave events. Elements   
      like phosphorus and copper are present in our bodies in only small   
      amounts but are essential to the functioning of all known life. The   
      featured periodic table is color coded to indicate humanity's best   
      guess as to the nuclear origin of all known elements. The sites of   
      nuclear creation of some elements, such as copper, are not really well   
      known and are continuing topics of observational and computational   
      research.
