Leveraging asteroseismology, stellar abundances and kinematics to derive precise ages for a sample of 95 stars, Montalbán et al. determine that the Milky Way was already host to a substantial population of stars when it was just 3.8 billion years old, at the time of the Gaia-Enceladus accretion event.
