Magnetic Funnel Around a Supermassive Black Hole

August 23, 2013
The accretion disk of hot plasma swirling around a supermassive black hole generates powerful magnetic fields. The disk's rotation twists the field into a funnel shape. These field lines constrict and direct the outflow of high-speed plasma from the black hole's vicinity. The result is a narrow, tapered, extragalactic jet. Credit: NASA, ESA, and A. Feild (STScI)
