To detect the gravitational wave background, astronomers studied fast-spinning stars called millisecond pulsars, which are dead stars that spin up to 700 times per second with astonishing regularity, blasting out beams of light from their magnetic poles, which are seen as "pulses" when they flicker in Earth's direction. Cosmic lighthouses as gravitational wave detectors Scientists report that the observed background hum of gravitational waves has grown in significance over time, providing tantalizing proof that there may be hundreds of thousands or even millions of supermassive black holes about to merge in the next few hundred thousand years, even though the gargantuan objects themselves haven't yet been spotted. During this process, they release energy in the form of gravitational waves that reverberate throughout the universe - waves astronomers now say they have detected. They say the signals may be coming from merging supermassive black holes that are caught in cosmic dances, circling each other in orbits that shrink across millions of years.

Hints of the same signal were announced in a series of papers published by scientists in China, India, Europe and Australia.
