At the center of our galaxy lies a swirling, energy-spewing supermassive black hole called Sagittarius A* or Sgr A*, for short. For billions of years, surrounding gas and dust have been falling into it. Every 10,000 years or so, it swallows a nearby star.
An international consortium of scientists who are part of the Event Horizon Telescope project announced that they have imaged the magnetic fields around a black hole. Brandeis Professor John Wardle explains the significance of the new image.
