Which elements are ejected back into space when stars die to help form new stars and planets?
Answer
Elements like carbon, oxygen, and iron
Dying stars act as cosmic factories, creating essential elements like carbon, iron, and oxygen during their lives or during the violent explosions of supernovae. When these stars die, they distribute these materials back into space. This material mixes into new nebulae, providing the building blocks necessary for future stars, planets, and the eventual development of complex life.
