Core Insights - The Event Horizon Telescope (EHT) collaboration, involving the Shanghai Astronomical Observatory, has released new images of the supermassive black hole at the center of the M87 galaxy, revealing the evolution of polarized radiation over time [1][3]. Group 1: Research Findings - Scientists have discovered extended radiation connecting the black hole's ring structure to the base of its jets for the first time in EHT data [3]. - The M87 black hole is located 55 million light-years from Earth and has a mass approximately 6.5 billion times that of the Sun [3]. - The polarization direction of the black hole changed significantly from 2017 to 2021, indicating a reversal in 2021 after being stable in 2018 [3]. Group 2: Implications of Findings - The evolution of polarization reflects the turbulent environment around the black hole, with magnetic fields playing a crucial role in how matter falls into the black hole and how energy is released [3]. - Powerful jets like those from M87 influence star formation and energy distribution on a large scale, contributing to galaxy evolution [3]. - The latest findings provide important insights into the mechanisms behind extreme cosmic phenomena, acting as a unique "laboratory" for research [3]. Group 3: Technological Advancements - The EHT has enhanced its observational capabilities, improving sensitivity and imaging clarity with the addition of new telescopes in 2021 [4]. - Upgrades to existing telescopes, including those in Greenland and the James Clerk Maxwell Telescope, have further improved data quality [4].
