One of the fastest growing fields in astrophysics is gravitational waves – what scientists call ripples in the fabric of space-time, first predicted by Albert Einstein in 1915.
A hundred years later, in September 2015, they were actually detected by ultra-sensitive lasers.
But others are searching for gravitational waves with pulsars - the dead relics of massive stars. Astronomers detect pulsars by the radio pulses they emit at regular intervals.
Enter Justin Ellis, just 30 years old, from a rural area outside of Charles Town in Jefferson County, WV.
