First-seen neutron star collision creates light, gravitational waves and gold

Welcome to the era of multi-messenger astrophysics – a single event in the cosmos that gives off both gravitational and electromagnetic waves. That's what the Aug. 17, 2017, detection by the LIGO Scientific Collaboration of two neutron stars merging means for the scientific community, which is celebrating yet another discovery that confirms a century-old theory from Albert Einstein. Once again, School of Physics Professor Laura Cadonati, LIGO's deputy spokesperson, is proving to be very quotable. "We can now fill in a few more tiles in the jigsaw puzzle that is the story of our universe," Cadonati tells CNN.
