M87* Throws a Gamma Fling

The Event Horizon Telescope (EHT) has spotted a rare gamma-ray flare from the supermassive black hole M87* on Dec 10, 2024. Lasting three energetic days, this flare emitted teraelectronvolt photons, outshining typical emissions by billions. Collaborators including Fermi, MAGIC, and HESS joined forces to capture the event, akin to a cosmic whale splashing near a bacterium-sized horizon. This discovery offers fresh insights into particle acceleration and the dynamic ballet of black hole jets, tickling scientists' curiosity and fueling cosmic conversations.
