The oldest stars in the outer regions of the Milky Way contain the fossil record of the events that occurred before they were born, specifically the explosions of the First Stars formed in the universe. The oldest stars have a chemical signature that is distinct from those of younger stars like the Sun. Observing these stars reveal events that occurred in the early galaxy, from the Big Bang to the lives and deaths of the First Stars to the formation of the elements of the periodic table.
Julie Hollek is an astronomer by day and a gastronomer by night, unless she’s observing in which case she’s also an astronomer by night.
