The Laser Interferometer Gravitational Wave Observatory (LIGO) in the US and the Virago Gravitational Wave Observatory in Italy captured the gravitational waves from the death spiral and merger of a neutron star with a black hole, not once but twice. The findings were recently published in The Astrophysical Journal Letters

The most massive gravitational waves ever

A binary black hole merger probably created gravitational waves equal to the energy of eight suns * "Bang" in the Ligo and Virgo detectors is a signal for the source of the most massive gravitational waves ever

"With the LIGO upgrade we will be able to discover dozens of gravitational wave events per year"

A collaboration between three observatories resulted in another discovery of gravitational waves

The Wirgo gravitational wave detector near Pisa in Italy is supposed to return to operation in the spring of 2017, and thus it is possible that three detectors of this type will operate together, in three different places in the world, for at least a month. Source: The Virgo collaboration.

A new detector will determine the origin of gravitational waves
