Iron is not just a common element found in the Earth’s crust; it plays a pivotal role in the very fabric of the universe. In fact, iron is the most abundant element produced in massive stars during their life cycles. As these stars exhaust their nuclear fuel, they undergo supernova explosions, scattering iron and other heavy elements across the cosmos. This process is crucial because it enriches the interstellar medium with elements necessary for the formation of planets and life. On Earth, iron is an essential component of hemoglobin in our blood, allowing us to transport oxygen efficiently. This connection highlights how the life we experience is intricately linked to cosmic events that occurred billions of years ago, illustrating the profound relationship between stellar processes and biological existence.
