19/12/2016 Happy 3rd birthday to Gaia!

Since the launch of Gaia on 19 December 2013 Gaia performed an impressive number of astrometric, photometric and spectroscopic measurements. More than 60 billion times an object moved through the Gaia focal plane. The total amount of science data collected since launch can now be viewed through a new information page on mission status numbers.
