A BLACK hole at the centre of the Milky Way will be discussed by astronomer Professor Patrick Roche tonight in Oxford.

In the free talk, the Oxford University professor, who is also the chairman of the UK Infrared Telescope Board, will explain how we know the black hole exists and the new technologies being used to investigate this part of space.

The free event, which has been organised by Science Oxford as part of British Science Week, will take place at the Cheney School from 7.30pm.
