The double-pulsar system PSR J0737-3039A/B, which comprises two radio pulsars that orbit one another quickly and with high acceleration, is the best system that has been identified for tests of general relativity. Kramer et al. (p. 97, published online 14 September; see the 15 September news story by Cho) report precision timing observations for a 3-year period. With mass measurements possible, four independent tests confirm the validity of general relativity at the 0.05% level in the strong-field regime.
