Photograph of pulsar SXP 1062 in the Small Magellanic Cloud.
From the write-up at Wired Space Photo of the Day:
Most pulsars whirl around incredibly quickly, spinning many times per second. However, by exploring the expanding bubble around this pulsar and estimating its age, astronomers have noticed something intriguing: SXP 1062 seems to be rotating far too slowly for its age. It is actually one of the slowest pulsars known.
