    Gaia is so Accurate it Can Predict Microlensing Events
    The ESA’s Gaia Observatory continues its astrometry mission, which consists of measuring the positions, distances, and motions of stars (and the positions of orbiting exoplanets) with unprecedented precision.
    Astrometric microlensing can be used to make precise measurements of the masses of lens stars that are independent of their assumed internal physics.
