NANOGrav (North American Nanohertz Observatory for Gravitational Waves)

NANOGrAV (North American Nanohertz Observatory for Gravitational Waves) is a scientific project that uses a network of highly precise radio telescopes to detect very low-frequency gravitational waves—ripples in spacetime caused by massive cosmic events like merging supermassive black holes. By monitoring the timing of signals from pulsars (rapidly spinning neutron stars), NANOGrAV looks for tiny deviations that indicate passing gravitational waves. This research helps us understand the universe’s most massive and energetic processes, opening a new window to study cosmic phenomena that occurred billions of years ago.
