Gravitational Wave Event Likely Signaled Creation of a Black Hole

Client: NASA’s Chandra X-ray Observatory
Date: 2018
Caption: A new study using Chandra data of GW170817 indicates that the event that produced gravitational waves likely created the lowest mass black hole known. Artist’s illustration shows a key part of the process that created this new black hole, as the two neutron stars spin around each other while merging. (The purple material depicts debris from the merger.)
