LIGO and Virgo announce the detection of a black hole binary merger from June 8, 2017

News Release • November 15, 2017

Scientists searching for gravitational waves have confirmed yet another detection from their fruitful observing run earlier this year. Dubbed GW170608, the latest discovery was produced by the merger of two relatively light black holes, 7 and 12 times the mass of the sun, at a distance of about a thousand million light-years from Earth. The merger left behind a final black hole 18 times the mass of the sun, meaning that energy equivalent to about 1 solar mass was emitted as gravitational waves during the collision.

LIGO Detection of Colliding Neutron Stars Spawns Global Effort to Study the Rare Event

News Release • October 16, 2017

LIGO’s detection on August 17, 2017 of gravitational waves from merging neutron stars has spawned an explosion of new science across the global astronomical community. This detection is especially important to science because the waves were created by matter and not black holes. As such, a deluge of electromagnetic radiation was also produced in the process; something not associated with any of LIGO’s previous detections. Behind the scenes of this amazing discovery.
