SUMMARY: An international team of astronomers have discovered a double pulsar system - the first ever seen. The two objects orbit a common centre of gravity once every 2.4 hours; one rotates at 3000 times a minute, while the other spins at only 22 times a minute. This discovery is important because it will allow astronomers to test various theories of relativity as the two objects interact with each other. The two pulsars will probably merge to become a black hole in 85 million years.
