Gaia Data Release 3

The European Space Agency's (ESA) Gaia space observatory will release its third data catalogue on 13 June 2022. Numerous events around the world will celebrate this success from 10 am (CEST). More information and links to the registration as well as to the German-language event via Zoom is available on the corresponding news page.

On 13 June 2022, the third Gaia catalogue will be presented in parallel live streams from all over Europe: Gaia DR3 national events are offered in various languages from Belgium, Brazil, Croatia, Finland, France, Germany, Hungary, Italy, Poland, Slovenia, Spain, Switzerland and the United Kingdom.

In Germany, there are four institutions contributing to the Gaia catalogues: the Leibniz Institute for Astrophysics Potsdam (AIP), the Lohrmann Observatory at the Technical University of Dresden, the Max Planck Institute for Astronomy in Heidelberg, and the Astronomisches Rechen-Institut of Heidelberg University. They invite the interested public and journalists to a hybrid German Gaia DR3 opening event at the Haus der Astronomie in Heidelberg.

The German event will start at 11:00, after the central ESA/Gaia/DPAC press briefing stream on ESA WebTV at 10:00 in English. At 12:00 the data will become available to the public through the Gaia Archive and the Gaia partner data centres.
