Measuring the Universe with the Gravitational Lens Effect

The series "Bonner Sternenhimmel" is a collaboration between the Bonn Observatory, the Argelander Institute for Astronomy and the MPI for Radio Astronomy. Dr Robert Reischke, from the Argelander Institute, will give a talk on "Measuring the Universe with the Gravitational Lens Effect" (in German).

It is not necessary to register for the event.

Weather permitting, observations may be done following the talk, at the telescope in front of the building after the lecture.
