The waves are generated by two black holes that spiral around each other, then collide and merge

In the bright green regions, the waves stretch space; in the dark green regions, they squeeze space. As the black holes near each other, the waves get stronger and the separation between them gets shorter, giving rise to a “chirp”. The two black holes collide and merge into a new black hole, bringing the waves to a crescendo. The newborn black hole vibrates briefly, then becomes quiet and stops generating waves. The waves depart from the hole’s vicinity, traveling out into the universe, carrying news of the black holes’ collision.
