Astrophysicists unveil glut of gravitational-wave detections

Gravitational-wave observatories have released their latest catalogue of cosmic collisions, including one featuring the lightest neutron star ever detected in this way, as well as two clashes involving surprisingly large black holes. The detections come from the LIGO and Virgo observatories in the United States and Italy, respectively, which made the landmark first detection of gravitational waves in 2015.
