General relativity survives gruelling pulsar test
The Commonwealth Scientific and Industrial Research Organisation

Astronomers have used a pair of pulsars orbiting each other, found with CSIRO’s Parkes telescope in 2003, to show that Einstein’s theory of general relativity is correct to within 0.05% – the most stringent limit to date.
15 September 2006

They also hope to be able to use the two pulsars to determine the exact nature of the matter that pulsars and other neutron stars are made of.

Their results are to be published in the journal Science, and made available online in Science Express on 14 September 2006.

An international research team led by Professor Michael Kramer of the University of Manchester's Jodrell Bank Observatory, UK, has been observing the double-pulsar system since 2003 with three of the world’s largest radio telescopes: CSIRO’s Parkes radio telescope in NSW, Australia; the Lovell Telescope near Manchester, UK; and the Robert C. Byrd Green Bank Telescope in West Virginia, USA.
