Scientific results from the Gaia mission - A new view of our galaxy (MVSem, WS18/19)

Master Pflichtseminar

If the time of the seminar is not fitting into your schedule, please send an Email to In that case we may be able to find a new date.

This seminar aims at presentations of scientific results from the Gaia mission. The second Gaia catalogue containing data for more than 1.7 billion stars was published on April 25, 2018 and changed our view of the stars and our Milky Way. Within five months the Gaia Data Release 2 led to more than 400 scientific papers from dozens of different fields of astronomy. The idea of this seminar is to choose the most interesting and fascinating results as topics for presentations and to learn more about the Gaia data which will revolutionise our understanding of the Milky Way and the stars.
