Since Einstein@Home hasn't got this news (yet): http://www.nature.com/news/european-detector-spots-its-first-gravitational-wave-1.22690
Physicists have announced their fourth-ever detection of gravitational waves, and the first such discovery made together by observatories in Europe and the United States.
The Virgo observatory near Pisa, Italy, has been hunting for ripples in the fabric of space-time since 2007. But it was being upgraded at the time of the historic first detection of gravitational waves by the twin laboratories of Virgo’s US cousin, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), and was also out of action for two subsequent sightings.
Virgo rejoined the hunt this year on 1 August, following a 5-year, €23-million (US$27-million) upgrade. And on 14 August, both it and LIGO picked up the spiral of a pair of rotating black holes, with masses of 31 and 25 times that of the Sun, as they merged together, physicists announced on 27 September at a press conference in Turin, Italy. The collision happened around 540 million parsecs (1.8 billion light years) away.
