This artist’s conception shows two merging black holes similar to those detected by LIGO. The black holes are spinning in a nonaligned fashion, which means they have different orientations relative to the overall orbital motion of the pair. LIGO found hints that at least one black hole in the system called GW170104 was nonaligned with its orbital motion before it merged with its partner.

The Laser Interferometer Gravitational-wave Observatory (LIGO) has made a third detection of gravitational waves, ripples in space and time, demonstrating that a new window in astronomy has been firmly opened. As was the case with the first two detections, the waves were generated when 2 black holes collided to form a larger black hole...

LIGO’s 1st detection of merging black holes ‘perfectly consistent’ with Northwestern model. In a new study, the scientists show their theoretical predictions last year were correct: The historic merger of 2 massive black holes detected Sept. 14, 2015, could easily have been formed through dynamic interactions in the star-dense core of an old globular cluster. These binary black holes are born in the chaotic “mosh pit” of a globular cluster, kicked out of the cluster and then eventually merge into one black hole. This theory, known as dynamical formation, is 1 of 2 main channels for forming binary black holes detected by Advanced LIGO (Laser Interferometer Gravitational-Wave Observatory).

Colliding black holes do not emit light; however, they do release a phenomenal amount of energy as gr...

On Sept. 14, 2015, LIGO detected gravitational waves from two merging black holes, shown here in this artist’s conception. The Fermi space telescope detected a burst of gamma rays 0.4 seconds later. New research suggests that the burst occurred because the two black holes lived and died inside a single, massive star. Credit: Swinburne Astronomy Production

On Sept14, 2015, Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of 2 black holes 29 and 36 times the mass of the Sun. Such an event is expected to be dark, but the Fermi Space Telescope detected a gamma-ray burst just a fraction of a second after LIGO’s signal...
