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 polarization 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*.

"Milky Way black hole"

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the center of our Galaxy: how it looks in polarized light.

This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of Sagittarius A*.

This image shows the polarized view of the Milky Way black hole. The lines mark the orientation of polarization, which is related to the magnetic field around the shadow of the black hole. Image
