Counting stars with Gaia 03 July 2015 This image, based on housekeeping data from ESA's Gaia satellite, is no ordinary depiction of the heavens. While the image portrays the outline of our Galaxy, the Milky Way, and of its neighbouring Magellanic Clouds, it was obtained in a rather unusual way. Read more
Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population.

Surveying A Billion Stars - The Gaia Blog
Time-out for blog while catalogue production is underway 10 October 2014 Now that science data have started to flow, the main activity for scientists working on the mission is preparing for the first catalogue release, planned for summer 2016. So while they are busy with that important task, we will take a break on the blog. Read more
Gaia in your pocket - mapping the Galaxy with the new Gaia app 01 September 2014 Mapping one billion stars in our Galaxy may seem like an impossible feat, but that's exactly what ESA's Gaia mission aims to do, with the ultimate goal of creating the largest, most precise 3D map of our Galaxy ever made. And now you can follow the mission's progress with a new app created by the University of Barcelona. Read more

Gaia movie - Impressions from the AGIS meeting in Heidelberg 09 June 2015 Video on the Gaia mission and its goals. It features members of Gaia's Data Processing and Analysis Consortium (DPAC) explaining the Astrometric Global Iterative Solution (AGIS) – a mathematical procedure that will determine the positions, movements and distances of about one billion stars measured by Gaia, resulting in the most accurate star catalogue ever.
