New image of the Milky Way black hole reveals powerful magnetic fields

Scientists of the Event Horizon Telescope (EHT) discovered the presence of powerful, organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*), at the center of the Milky Way.

Seen in polarized light for the first time, this new image of the “monster lurking” at the heart of the Milky Way revealed the existence of a magnetic field structure strikingly similar to that of the galaxy M87 black hole, suggesting that strong magnetic fields may be common to all black holes. This similarity also points to a hidden jet in Sgr A*.

The research is published in two articles in the journal The Astrophysical Journal Letters, led by the EHT collaboration, in which more than 300 researchers from Africa, Asia, Europe, North America and South America are involved.
