Figure 1 (IMAGE) Moscow Institute of Physics and Technology Caption At the center of a quasar, a black hole is surrounded by a spinning accretion disk composed of dust and gas, and there are two oppositely directed plasma jets emanating from it. The shape of the jets changes with distance from the center, and as a result, they look like the famous flared pants. In this artist's rendering, a twisted magnetic field and clouds of interstellar gas can be seen around the jet.
