Black hole evolution: By comparing EHT results from 2017 that were re-analysed using a Bayesian approach (left), to observations made in 2018 (right), astronomers can begin to understand how the black hole M87* evolves over time. (Courtesy: Ilje Cho)
New statistical analyses of the supermassive black hole M87* may explain changes observed since it w
