European Space Agency's (ESA) Gaia space telescope is instrumental to scientific research as it creates a 3D map of the Milky Way. The spacecraft measures the positions and trajectories of roughly two billion stars so that astronomers can witness the changing nature of the galaxy over billions of years. This astronomical mission has produced the most scientific papers since its launch.
