Today the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center released the results of 15 years of data in a set of papers published in The Astrophysical Journal Letters. This research is the first evidence of gravitational waves at very low frequencies. The team, comprised of 190 scientists, including SETI Institute researcher Dr. Michael Lam, transformed our region of the Milky Way Galaxy into an immense gravitational- Less
