A star’s chemical composition strongly influences the ultraviolet radiation it emits into space and thus the conditions for the emergence of life in its neighbourhood.
A single star has provided information about the collision of the Milky Way with the dwarf galaxy Gaia-Enceladus. The event likely took place approximately 11.5 billion years ago.
