Astronomers spot hyper-velocity star hurtling through space

Astronomers have spotted a star tearing through the Milky Way that appears to have been flung outwards following an encounter with the super massive black hole at our galaxy’s heart. It is travelling through the galaxy at a blistering speed of more than 1700 kilometres per second. Compare that to the stately 16.08 km/s of the Voyager 2 spacecraft launched in 1977 and you will have an idea of how far we still have to go to reach the stars.
