"A massive collision between two black holes 1.4 billion light-years away has yielded a second set of gravitational waves for scientists with theLaser Interferometer Gravitational-Wave Observatory (LIGO).
The news comes just a few months after LIGO scientists announced the world's first direct evidence of gravitational waves, and a century after Albert Einstein first described them in hisGeneral Theory of Relativity.
The first gravitational waves were detected on September 14, 2015, just three days after the LIGO facility was turned back on after a five-year upgrade to make the instrumentation more sensitive"
