Stars, like human beings, have a lifetime and eventually collapse to form white dwarfs, dense planetary-sized cores made of carbon and oxygen. The explosion of a white dwarf, known as a supernova, such as SN 2018 gv, allows us to map the evolution of the universe by measuring distances to galaxies.
