Why are Supernovas important to life on earth?

1 Answer

When universe started from Big bang there was only hydrogen and helium.


Other elements up to Iron in periodic table were cooked up in the core of stars due to fusion..But heavier elements were made in supernova explosions of massive stars..So most elements on earth is the result of a supernova. Sun a second or third generation star is also formed from the products of a supernova..With out Sun and heavy elements there will not be any life on Earth.
