Caption: The unusual PSR J1311-3430 pulsar system with the first millisecond pulsar discovered solely by its lighthouse-like gamma-ray emissions (magenta). The record-breaking pulsar system is so compact that it would fit completely inside our Sun. This schematic representation shows the Sun, the companion's orbit, and the companion at its maximum possible size true to scale; the pulsar has been greatly enlarged in contrast.
