She's referring to more than 70 observatories around the world that helped confirm the first-ever detection of gravitational waves and light caused by the merger of two neutron stars. The resulting explosion and lightshow those astronomers witnessed from the merger is called a kilonova, and it's the source of Earth's heavy elements like gold, silver, and platinum.
