Gravitational wave observations

LIGO and Virgo detect a gravitational wave from a galaxy 6 billion light-years away in the direction of Cassiopeia, with further details being released on April 10.

One week after LIGO switched back on, it has already detected the gravitational waves from another pair of merging black holes, marking the beginning of a new era of gravitational wave astronomy
