Galaxies are like giant kitchens where, in stellar cores, light atoms are fused into heavy ones — much like flour and water becoming bread. When a star dies, it spills its accumulated riches into the interstellar gas, seasoning it with 'spices': oxygen, carbon, iron.

A vast city lights new streetlamps every night. But then a hurricane sweeps in, rips all the fuel from the warehouses, and the lamps go out one by one. Something similar has been spotted by astronomers in a galaxy whose light has traveled 12.5 billion years to reach us.
