We are pleased to announce the IAU symposium 330 - Astrometry and Astrophysics in the Gaia sky, to be held in Nice (France), from 24-28th April 2017.


The first release of the Gaia data has been made publicly available on september 14, 2016. Besides a catalogue of 1.1 billion source positions and broad-band G-magnitudes, this DR1 also includes the positions, G-magnitudes, parallaxes, proper motions for 2 million stars in common between the Tycho-2 Catalogue and Gaia (TGAS). Light curves for 3194 Cepheids and RR Lyrae are also part of the release as well as a special astrometric solution for 2152 ICRF quasars.
The goal of this IAU symposium is to ensure the world-wide sharing of the Gaia mission results that will cover the following topics: astrometry and reference frames, Milky Way galaxy and stellar physics and the Solar system bodies. 
More details are available at the conference website: 
We look forward to seeing you in Nice next April.
