New observations of the black hole M87*, the first one to have been photographed, show that it changes shape, which was not planned by scientists. What are these strange evolutions hiding?
The supermassive black hole M87* was photographed first. Now there are more photos of the object and the show surprising changes.
New EHT Images Reveal Dynamic Magnetic Fields at M87*
September 16, 2025 — The Event Horizon Telescope (EHT) collaboration, with major contributions from the Max Planck Institute for Radio Astronomy (MPIfR), has unveiled new images of the supermassive black hole at the center of galaxy M87. For the first time, the EHT detects faint emission from the base of M87’s relativistic jet, while multi-year observations from 2017 to 2021 reveal unexpected flips in polarized light, showing that magnetic field…
New Images of M87's Black Hole Show its Changing Magnetic Field
New Images of M87's Black Hole Show its Changing Magnetic Field | ESOIn 2017, the Event Horizon Telescope (EHT)—a worldwide network of radio-telescopes—observed the supermassive black hole at the center of the M87 galaxy, leading to the first ever image of a black hole, released in 2019. Now, using observations from 2017, 2018 and 2021, astronomers have found changes in this now iconic image that could be caused by variations in the magnetic fie…
