The discovery of the double radio pulsar system, PSR J0737 -3039A/B, surpassed most expectations, both theoretical and observational, as a tool to probe general relativity, stellar evolution and pulsar theories. I will describe rich observational properties of the system, like eclipses, orbital variations in magnetospheric activity, evidence for relativistic reconnection, trapped magnetospheric particles.

The system allows a measurement of the relativistic spin precession and offers a new test of theories of gravity in strong regime. We can also pin-point the location and the shape of the region producing enigmatic coherent radio emission.
