An international team of scientists from the UK, Australia, Italy and the USA have announced in the today’s issue of the journal Science Express (8th January 2004) the first discovery of a double pulsar system.
They have shown that the compact object orbiting the 23-millisecond pulsar PSR J0737-3039A with a period of just 2.4 hours is not only, as suspected, another neutron star but is also a detectable pulsar, PSR J0737-3039B, that is rotating once every 2.8 seconds.
