'''PSR J0737−3039''' is the first known double [[pulsar]]. It consists of two [[neutron star]]s emitting [[Electromagnetic radiation|electromagnetic waves]] in the radio wavelength in a relativistic [[binary system]]. The two pulsars are known as PSR J0737−3039A and PSR J0737−3039B. It was discovered in 2003 at [[Australia]]'s [[Parkes Observatory]] by an international team led by the Italian radio astronomer [[Marta Burgay]] during a high-latitude pulsar survey.<ref>{{Cite journal |last1=Burgay |first1=M. |last2=d'Amico |first2=N. |last3=Possenti |first3=A. |last4=Manchester |first4=R.
