Located about 55 million light-years away from Earth, M87 harbors a supermassive black hole more than six billion times the mass of the Sun. It is designated as M87*. The Event Horizon Telescope (EHT), a global network of radio telescopes acting as an Earth-sized observatory, first captured the iconic image of M87’s black hole shadow in 2019. Now, by comparing observations from 2017, 2018, and 2021, scientists have taken the next step towards uncovering how the magnetic fields near the black hole change over time. The new images reveal a dynamic environment with changing polarization patterns near the black hole. Additionally, the scientists found the first signatures of the extended jet emission near the jet base, which connects to the ring around M87*. These new observations are providing new insights into how matter and energy behave in the extreme environments surrounding black holes.
