“First Gaia local group dynamics: Magellanic Clouds proper motion and rotation” by van der Marel and Sahlmann reveals how eager astronomers are to explore and exploit the exquisite parallaxes and proper motions promised by this European Space Agency (ESA) space mission
Astrometry has kept his stronghold in Europe and the European Space Agency (ESA) has been a key player to continue this role
Summary
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. Astrometry, as the brand of astronomy in charge of measuring the positions and motions in the sky of stars and other space objects, is mainly concerned with the determination and definition of the most precise and accurate reference frame in space with respect to which astronomical observations can be located.
