Windy black holes

Stories from Physics for 11-14 14-16 IOP RESOURCES

Scientists have observed incredibly strong ‘winds’ emanating from black holes. The ultra-fast outflows are emitted from the accretion disc of material that orbits a black hole and have been measured to reach velocities of up to a quarter of the speed of light. The flows absorb X-rays emitted from the black hole and are heated to millions of degrees.
