CAMBRIDGE - The positions of the cataloged pulsars shown in a top-down view of the Milky Way. The red and orange symbols indicate millisecond pulsars, while the green and blue symbols indicate young, unrecycled pulsars. Some radio-quiet pulsars (blue symbols) do not have well measured distances, so their positions only indicate the direction towards these pulsars.
