The Atlantic : Despite making history with their announcement in February of the first direct detection of gravitational waves, researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) aren’t resting on their laurels. On Wednesday they announced a second confirmed gravitational-wave detection. The gravitational waves detected on 26 December 2015 were caused when two black holes merged about 1.4 billion years ago.
