These images of M87*, located around 55 million light-years from Earth, show that the polarisation of the magnetic fields around the black hole reversed over a period of four years

The Event Horizon Telescope (EHT) has captured stunning, newly revealed images of the supermassive black hole that lies at the heart of the galaxy M87. The EHT made this black hole, known as M87*, famous in April 2019 when it was revealed as the first black hole ever imaged by humanity.

These images of M87*, located around 55 million light-years from Earth, show that the polarisation of the magnetic fields around the black hole reversed over a period of four years. The new observations of M87* also show the telltale signs of a jet of matter emerging from around the black hole, with its base connected to the bright ring around the outer boundary, or “event horizon,” around M87*.


The images could help further develop theories of how matter behaves in extreme environments around supermassive black holes, which have masses of millions or even billions of suns and are found at the heart of large galaxies.
