Pulsars are rapidly spinning neutron stars which release blasts of radio waves with atomic clocklike accuracy. The fastest can be turning hundreds of times a second. But another class of pulsars turns agonizingly slowly in comparison, completing a rotation in hours. Astronomers have termed these "spider pulsars" because they have to feast on a binary companion star to slow down like this. Now researchers have discovered the fastest-turning spider pulsar, completing a rotation every 53 minutes, which fills in a gap in their observations.
