Incredible new image shows the magnetic fields at the edge of the M87 black hole

The Event Horizon Telescope (EHT) collaboration has published a new view of the black hole at the center of the M87 galaxy. The EHT published the first-ever image of a black hole in 2019. This time, the image shows the black hole in polarized light, which shows the magnetic field surrounding the black hole. This marks the first time astronomers have been able to measure polarization this close to the edge of a black hole. Polarization is a signature of magnetic fields, and being able to observe ...
