History

Historical Context

The Event Horizon Telescope (EHT) collaboration unveiled the first image of a black hole, M87*, on April 10, 2019, marking a pivotal moment in astrophysics. This achievement, involving over 200 researchers, tested Einstein's general relativity and provided insights into black hole dynamics. The recent observation of a shockwave in OJ287's jet builds on this legacy, potentially reshaping our understanding of gravity and the universe.
