Outflow from active galaxy NGC 3783 (artist���s impression)

This video shows an artist���s impression of the dusty wind emanating from the black hole at the centre of galaxy NGC 3783. Astronomers knew that dust surrounded such supermassive black holes in a doughnut-shaped torus, but new observations using ESO���s Very Large Telescope Interferometer now show that dust also lies in the polar regions. This material is pushed outwards by the black hole���s radiation, forming a cool, dusty wind.
