NRL Scientists Use Pulsar Timing to Measure Gravitational Waves From the Distant Universe

WASHINGTON – The U.S. Naval Research Laboratory’s Space Science Division, along with a team of international scientists, discovered groundbreaking evidence for gravitational waves that stretch and squeeze spacetime. The gravitational wave signal was observed in pulsar observations taken over the past 15 years by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), a collaboration of more than a hundred scientists from the United States and Canada.
