A team of international scientists have found the first evidence of a cosmic gravitational wave background across the universe.
Supermassive black holes generate gravitational waves as they merge. NANOGrav, has collected high-precision data for over 15 years using ground-based radio telescopes.
Background ripples detected by NANOGrav help understand gravitational wave creation and the dynamics during propagation.
The discovery complements LIGO’s 2015 detection of shorter-wavelength gravitational waves from black holes 30 times the mass of the Sun. NASA supports the future Laser Interferometer Space Antenna mission for detecting gravitational waves in a wavelength range between NANOGrav and LIGO.
NANOGrav is a National Science Foundation-funded Physics Frontiers Center of more than 190 scientists from the United States and Canada, including scientists at NASA’s Jet Propulsion Laboratory in Southern California and other NASA centers.
