Globular clusters, such as M3 pictured above at optical wavelengthes (Barbara Mochejska (Warsaw University), Andrew Szentgyorgyi (CfA), FLWO) contain as many as one million gravitationally bound stars. These high density clusters are ideal hunting grounds for millisecond pulsar (MSP) searches, as globular clusters are known to be populated by older stars, and MSPs are typically the oldest pulsars. Read this NRAO press release about the discovery of 21 new pulsars in another globular cluster named Terzan 5 for a general description of pulsar search techniques. McGill Pulsar Group member Jason Hessels and ex-member Scott Ransom have also been responsible for the discovery of 14 additional MSPs in globular clusters, described in the following publications: A Radio Pulsar Spinning at 716 Hz.
