An ‘interstellar interferometer’ related to a double imaging of the pulsar PSR 1237+25 by refraction in the interstellar medium has been used to resolve the pulsar magnetosphere for the first time. With an interferometer baseline ∼ 1 AU, we have measured a typical transverse separation between the emitting regions of PSR 1237+25 to be ∼ 108 cm, or an angular separation ∼ 0.02 μas.
