The universe is haunted by “cosmic ghosts” called neutrinos, and new research suggests they may be the “whispers” of stars that died in supernova explosions over the course of billions of years. The discovery is an important step forward in our understanding of the life and death of stars and how they enrich their environments with metals, elements heavier than hydrogen and helium. It…
