This beautiful globular cluster harbours 22 millisecond pulsars with periods between 2 and 8 ms. Many of them have a binary companion. We can estimate that hundreds more of these objects are in the cluster, but they may be too weak to be detected.

The video is an animated tour of the cluster, with the pulsars occupying the 3D positions determined from timing observations. The sounds are the true sounds of the pulsars, but their images are rotating several hundred times slower than reality.
