Pulsars as Cosmic Lighthouses
Quick fact
The fastest known pulsar, PSR J1748−2446ad, spins about 716 times per second — faster than a kitchen blender.

Have you ever seen a lighthouse beam sweeping across the sea, appearing and disappearing with a steady rhythm? Now imagine that same effect happening on a cosmic scale, with a city-sized star spinning hundreds of times per second.
