There is a giant black hole at the center of our galaxy, a study has confirmed.

German astronomers tracked the movement of 28 stars circling the centre of the Milky Way, using two telescopes in Chile.

The black hole is four million times more massive than our Sun, according to the paper in The Astrophysical Journal.

According to Dr Robert Massey, of the Royal Astronomical Society (RAS), the results suggest that galaxies form around giant black holes in the way that a pearl forms around grit.
