Gaia – Teamwork for a billion stars
From 16-20 November 2015 more than 200 scientists and engineers of the Gaia Data Processing and Analysis Consortium (DPAC) met in Leiden, Netherlands. They discussed the status and progress of the Gaia mission in preparation of the first Gaia data release, which is planned for late summer 2016.
The GENIUS documentary by Klaus Jäger and Stefan Jordan explains the main goals of the Gaia mission. It also contains interviews and statements from several scientists directly involved in the analysis of the Gaia data. The documentary shows that Gaia is a mission covering many different aspects in astronomy and physics, and also explains how the joint teamwork from more than 400 scientists and engineers will lead to the most precise star catalogue ever.
Gaia – with impressions from the AGIS Meeting in Heidelberg
A DPAC outreach movie by Klaus Jäger in collaboration with Stefan Jordan
On April 8 -10, 2015, 22 members of the Gaia Data Processing and Analysis Consortium DPAC met at the Center for Astronomy of the University of Heidelberg in order 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.
Klaus Jäger and Stefan Jordan have produced a 15 minute DPAC outreach video which explains the Gaia mission and its goals. The movie contains interviews with Lennart Lindegren, the intellectual father of AGIS, with Uwe Lammers, the Gaia Science Operations Manager, and with 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.
The movie is available in German and English.
