A Pulsar Timing Array (PTA) is a scientific method used to detect and study gravitational waves through the precise monitoring of millisecond pulsars. Millisecond pulsars are highly stable rotating neutron stars that emit beams of radio waves, which can be observed from Earth. The timing of the arrival of these radio pulses can be measured with extreme precision, often to within nanoseconds.
