This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “PIA19822-MagneticBlackHoleWaves-AlfvenS-waves-20150709.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

Summary

Description
English: PIA19822: Magnetic Black Hole Waves

http://photojournal.jpl.nasa.gov/catalog/PIA19822

This cartoon shows how magnetic waves, called Alfven S-waves, propagate outward from the base of black hole jets. The jet is a flow of charged particles, called a plasma, which is launched by a black hole. The jet has a helical magnetic field (yellow coil) permeating the plasma. The waves then travel along the jet, in the direction of the plasma flow, but at a velocity determined by both the jet's magnetic properties and the plasma flow speed. The BL Lac jet examined in a new study is several light-years long, and the wave speed is about 98 percent the speed of light.
