Abstract: This paper proposes that pulsars can serve as beacons for the discovery of and
communication with extraterrestrials. The motivation for the communication strategy proposed is
discussed in detail, along with relevant astrophysical considerations. It is shown that millisecond pulsars
have characteristics and a distribution in space that make it possible to envisage communication being
targeted towards and away from habstars (as defined by Turnbull & Tarter) aligned with pulsars in a
specified way. Lists of candidate habstars and their pulsar alignments are included for those wishing to
conduct searches using the strategy described.
