happy anniversary Gaia

Stumbled across the article at the European Space Agency site on the one year anniversary of the Gaia probe. It was interesting to learn that it is working well. It has recorded:
  • 272 billion positional or astrometric measurements 
  • 54.4 billion brightness or photometric data points
  • 5.4 billion spectra
On its way to improving our stellar epoch data.
