100 years ago, Einstein predicted the existence of gravitational waves. These ripples in the space-time geometry propagate at the speed of light and are witness to some of the most energetic events in the Universe. Following a major upgrade, the two detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) held their first observation run between September 2015 and January 2016. On September 14th, 2015 the Advanced LIGO detectors observed the transient gravitational-wave signal GW150914, determined to be the merger of two black holes, launching the era of gravitational-wave astronomy. A second robust binary black hole coalescence was observed later in the year on December 26.
