Millisecond Pulsars Could Make 'Galactic GPS' Possible

By studying unknown high-energy sources detected by NASA's Fermi Gamma-ray Space Telescope, radio astronomers have uncovered 17 millisecond pulsars in our galaxy. The  discovery was made  in less than three months, and such a jump in the pace of locating these hard-to-find objects holds the promise of using them as a kind of "galactic GPS" to detect gravitational waves passing near Earth. read more
