A public ceremony will take place at Physics Faculty of the Universitat de Barcelona on the occasion of the Second Gaia Data Release tomorrow 25 April 2018.

Gaia’s second data release will include positions and brightnesses for nearly 1.7 billion stars, distances, proper motions and colours for 1.3 billion of them, velocities along the line of sight for a subset of seven million, and brightness measurements for half a million variable stars. It also extends the positions and brightnesses to more than half a million quasars, which will allow the celestial reference frame to be fully defined for the first time using optical observations.
