Following the mind-boggling release of the first image ever captured of a black hole, astronomers have done it again, revealing a new view of the massive celestial object and shedding light on how magnetic fields behave close to black holes

In 2019, the Event Horizon Telescope (EHT) collaboration produced the first-ever image of a black hole, which lies at the center of the M87 galaxy 55 million light-years from Earth. The image showed a bright ring with a dark center, which is the black hole’s shadow. In capturing this image, astronomers noticed a significant amount of polarized light around the black hole. Now, the collaboration has revealed a new look at the black hole, showing what it looks like in polarized light.
