Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                              2026 September 14
      [2]A chart is shown which a version of the periodic table of the
   elements. Each element has a thumbnail image that indicates how it was
     first created in the universe. Please see the explanation for more
                            detailed information.

                        Where Your Elements Came From

   Explanation: The hydrogen in your body and present in every molecule of
   water came from the [6]Big Bang. There are no other [7]appreciable
   sources of [8]hydrogen in the universe. The [9]carbon in your body was
   made by [10]nuclear fusion in the interior of stars, as was the
   [11]oxygen. Much of the iron in your body was made during
   [12]supernovas of stars that occurred long ago and far away. The
   [13]gold in your jewelry was likely made from neutron stars during
   collisions that may have been visible as short-duration [14]gamma-ray
   bursts or [15]gravitational wave events. Elements like phosphorus and
   copper are [16]present in our bodies in only small amounts but are
   essential to the functioning of all known [17]life. The [18]featured
   periodic table is [19]color coded to indicate [20]humanity's best guess
   as to the [21]nuclear origin of all known elements. The sites of
   [22]nuclear creation of some [23]elements, such as [24]copper, are not
   really well known and are continuing topics of observational and
   computational research.
