The Curious Case of the Vanishing Pulsars

In one of the more unexpected astronomical discoveries, scientists used the facility to detect two rather odd pulsars that stopped blinking for intermittent periods. The discovery, made in 2017, suggests pulsars don’t always blink, and that they have an “on state” and an “off state.” What’s more, this research suggests there may be more intermittent pulsars than “normal” pulsars.
