This month we learn about how pulsars can be used to detect gravitational waves. 1) Laura and Dusty provide an introduction to pulsars and pulsar timing 2) Dusty interviews Curran Muhlberger to find out what a gravitational wave is. 3) Laura interviews Prof. Maura McLaughlin of West Virgina University on the North American Nanoherz Observatory for Gravitational Waves (NANOGrav).
