M87* and the Jets
@ehtelescope imaged a black hole in the M87 galaxy; previously, @NASASpitzer saw jets and shockwaves emanating from it in infrared light. Teamwork! https://go.nasa.gov/2mVkNtH

where it is accelerated by the second key factor, the magnetic field around the black hole. This artist's concept from a NuStar release does a good job of conceptually relating what we think happens:https://www.nasa.gov/feature/jpl/nustar-probes-black-hole-jet-mystery …
So, if we imagine the classical magnetic field which we think about when we think about magnetic fields around a planet or a star, there are the closed loops of field lines around most of the star, and then there are the open field lines at the poles.https://www.nasa.gov/content/goddard/suns-magnetic-field-flips …
