The Event Horizon Telescope has unveiled how Sagittarius A*, the supermassive black hole at the centre of our galaxy, looks like in polarised light, which tells us a lot about the magnetic field around this monster.
The lines overlaid on the image below mark the orientation of the polarisation, from which astronomers can work out the structure of the magnetic field around the black hole.

  Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way’s central black hole
  
  from @ESO
  
  A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organised magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarised light for the first time, this new view of the monster lurking at the heart of the Milky Way galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the centre of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes. This similarity also hints toward a hidden jet in Sgr A*. The results were published today in The Astrophysical Journal Letters.
