In 2019, the Event Horizon Telescope captured the first image of the supermassive black hole in M87. 

 

Now, this black hole is once again in the spotlight with an extraordinary gamma-ray flare, emitting photons hundreds of billions of times more powerful than visible light. 

 

The flare, lasting three days, emerged from an area less than three light-days wide and provided new insights into how particles near black holes gain immense energy. 

 

The study, using data from multiple observatories, enhances understanding of high-energy particle acceleration and the processes within M87's powerful jet.
