    Towards the end of their lives some 95% of stars evolve into red giants which lose their mass via a “stellar wind”. Eventually they end up as planetary nebulae, ionized gas with a central hot star, a white dwarf. Here we report ALMA data on massive red giant (asymptotic giant branch, AGB) stars, displaying a spiral structure which show that these stars are not individual and have a binary companion. This offers an alternative explanation to the high rates of mass loss which it was thought were present towards the end of the lives of the most massive AGB stars. We show that these stars lose
