Other so - called hypervelocity stars are thought to have been boosted to their high speeds by close encounters with our galaxy's supermassive black hole (see Hypervelocity stars: Catch them while you can), but this star is too young to have travelled all the way from the centre of the Milky Way.

Having three detectors also enables researchers to make a rough measurement of the wave's polarization — a property that indicates how the black holes» orbital plane (the plane on which they rotate around each other) is orientated with respect to Earth.

The two US detectors, one in Washington and the other in Louisiana, saw the signal of a black hole merger just a few milliseconds apart, but with just two detectors the location of the source couldn't be pinned down.
