Where Do We Come From?

W1.3rd Day

In standard astronomy, the Big Bang produced hydrogen, helium, and traces of lithium, while all heavier elements are synthesized in stars and supernovae. Supernovae tend to enrich the surrounding interstellar medium with metals, which for astronomers means all of the elements other than hydrogen and helium and is a different definition than that used in chemistry.

A supernova is a relatively rare event occurring, on average, only once every 50 years in a galaxy the size of the Milky Way. However, supernovae have a significant role in enriching the interstellar medium with heavy elements, and the expanding shock waves from these explosions can trigger the formation of new stars.

Death of stars gives rise to new stars in cosmos: those elements spewed out of a dying star are what make up calcium in our bones and iron in the blood. Can we think of life on earth without oxygen? Or for that matter carbon? These two also are by courtesy of a supernova.
In a manner of speaking we are ‘star children’ shaped by stellar events.
