  • The recent spate of gravitational waves may come from pairs of stars that lived and died together. These gravitational waves are created when two black holes orbiting each other spiral inwards arid merge, producing a massive burst of energy. Last week, the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced it had found a second such ripple in space-time. Krzysztof Belczynski of Warsaw University and colleagues modeled how binary star systems could evolve into binary black holes like the source of the first LIGO signal. They started with two stars formed around 2 billion years after the big bang, one 96 times the mass of the sun, the other 50 times.
