A new view of the region closest to the supermassive black hole at the center of the galaxy has shown important details of the magnetic fields close to it—and hints about how powerful jets of material can originate in that region.
A worldwide team of astronomers using the Event Horizon Telescope (EHT) measured a signature of magnetic fields—called polarization—around the black hole. Polarization is the orientation of the electric fields in light and radio waves, and it can indicate the…
