last week, Gendreau and a team of NASA researchers announced that they had finally proven that pulsars can function like a cosmic positioning system. pulsar-measuring instrument the size of a washing machine, currently aboard the International Space Station) spent a weekend observing the electromagnetic emissions of five pulsars. With the help of an enhancement known as the Station Explorer for X-ray Timing and Navigation Technology (aka Sextant)
