Double pulsar PSR J0737-3039: Einstein is right again

The so far unique laboratory is located around 2,400 light years away in the constellation Puppis, the aft deck of the ship: There, two neutron stars orbit each other in just 147 minutes. They also rotate around themselves, and one neutron star only needs 44 milliseconds to rotate around its own axis. His companion is a bit more leisurely with 2.8 seconds. Researchers on earth notice something of this because both neutron stars act as pulsars that emit radio waves towards the earth. With the help of the radio signals from this double pulsar called PSR J0737-3039, an international team was able to thoroughly check Albert Einstein’s general theory of relativity. your results put it in the journal »Physical Review X« before.
