Stellar Parallaxes - How to measure stellar distances with the Gaia satellite
This video explains how stellar distances are measured with the Gaia satellite using the parallax method. The first Gaia catalogue will be published on 14 September 2016 and will contain about 2 million parallaxes and proper motions of stars additionally to the 1 billion stellar positions. Even the first Gaia catalogue will be the most precise star catalogue ever. The video, produced by Stefan Jordan, is available on YouTube. Subtitles are available in German, Spanish and Catalan.

Gaia movie – impressions from the AGIS meeting in Heidelberg
On 8 - 10 April 2015, 22 members of the Gaia Data Processing and Analysis Consortium (DPAC) met at the Centre for Astronomy of the University of Heidelberg to discuss the current status of AGIS. AGIS is the Astrometric Global Iterative Solution, a mathematical procedure that will determine the positions, movements and distances of about one billion stars from the individual measurements of the Gaia satellite.
This DPAC outreach video, produced by Klaus Jäger and Stefan Jordan, uses footage from the AGIS meeting, explaining the Gaia mission and its goals. The movie contains interviews with Lennart Lindegren, the intellectual father of AGIS, Uwe Lammers, the Gaia Science Operations Manager, and Ulrich Bastian, the scientific manager of the Gaia core processing. These three scientists explain what AGIS is and what its challenges are. They describe the progress of the AGIS development which will finally result in the most accurate star catalogue ever.
A German version of the movie is available here. For the English version, visit this YouTube page.
