On 30th of July 2017, the Max Planck Institute for Gravitational Physics and the Institut für Gravitationsphysik at Leibniz Universität Hannover invited the public for an Open Day at the gravitational-wave detector GEO600 south of Hanover. At six different detector stations researchers from the institute provided information about the importance of gravitational waves, their direct detection, the central contributions by GEO600, and the beginning of a new era of astronomy. An estimated 400 guests visited GEO600 on this Sunday afternoon.
On 12 November 2016 many institutes of Leibniz Universität Hannover opened for the public from 6 pm until midnight. Our institute was one of them and was visited by about 500 guests who attended our public talks, visited the supercomputer Atlas, talked to our scientists or played science-themed computer games.
On 31 July 2016 the GEO600 detector site was open to everyone interested in gravitational wave science. Apart from guided tours of the detector the visitor had the chance to chat with the scientists on site and to learn about LISA Pathfinder. About 800 guests visited GEO600 on this day.
