Which branch of astronomy is inaugurated by the LIGO and Virgo laboratories in 2016?
Answer
On February 11, 2016, the LIGO-Virgo collaboration officially announced that on September 14, 2015, the two LIGO observatories detected gravitational waves, an event named GW150914, produced by the coalescence of two black holes. This event inaugurates gravitational astronomy, a new branch of astronomy.
