Editing PSR J0737−3039 (section)

===Discovery===
PSR J0737−3039A was discovered in 2003, along with its partner, at Australia's 64&nbsp;m antenna of the [[Parkes Observatory|Parkes Radio Observatory]];  J0737−3039B was not identified as a pulsar until a second observation. The system was originally observed by an international team during a high-latitude multibeam survey organized in order to discover more pulsars in the night sky.<ref name="firstdp" />

Initially, this [[star system]] was thought to be an ordinary pulsar detection. The first detection showed one pulsar with a period of 23 milliseconds in orbit around a neutron star. Only after follow up observations was a weaker second pulsar detected with a pulse of 2.8 seconds from the companion star.
