The Gaia era has started

Abstract

Within hours of the first data release of the Gaia space astrometry mission, a paper in the arXiv repository appeared with results based on it. “First Gaia local group dynamics: Magellanic Clouds proper motion and rotation” by van der Marel and Sahlmann (http://arxiv.org/abs/1609.04395) simply reveals how eager astronomers are to explore and exploit the exquisite parallaxes and proper motions promised by this ESA space mission. The Gaia era has started.
