Black hole confirmed in Milky Way

I’m immediately reminded of that line from Red Dwarf:

Well, the thing about a black hole – its main distinguishing feature – is it’s black. And the thing about space, the colour of space, your basic space colour, is black. So how are you supposed to see them?

But, more to the point, this from the article:

There is a giant black hole at the centre of our galaxy, a 16-year study by German astronomers has confirmed.

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

The black hole, said to be 27,000 light years from Earth, is four million times bigger than the Sun, according to the paper in The Astrophysical Journal.

Black holes are objects whose gravity is so great that nothing – including light – can escape them.

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.
