Title: "The first double pulsar system - a unique testbed for relativsitic gravity"

We recently discovered the first double pulsar system. This system consisting of a 22-ms and a 2.8-s pulsar in a 2.4-hr orbit is the most relativistic system ever found. Its property of providing two clocks moving in a deep gravitational potential opens new ways of probing relativistic gravity and the study of neutron stars and pulsars in general. I will describe these opportunities, present the latest results and conclude with an outlook into the future where the Square-Kilometer-Array (SKA) promises the study of Black Hole physics with pulsars.
