For the first time, astronomers detect gravitational waves from two neutron stars colliding

The Aug.17, 2017, detection of gravitational waves and light from the merger of two neutron stars set off a race against time around the globe. Astronomers scrambled to confirm data that could be seen by telescopes and measured by gamma-ray, x-ray and radio wave detection equipment before they all faded away. Laura Cadonati, associate professor in the School of Physics and LIGO Scientific Collaboration deputy spokesperson, explains how these gravitational waves lasted longer than those from four previous incidents caused by black hole collisions. Cadonati is a member of the Center for Relativistic Astrophysics.
