In 2019, the first-ever image of a black hole captured global attention. This impressive achievement by the Event Horizon Telescope (EHT) unveiled the supermassive black hole at the heart of galaxy M87, also known as Virgo A or NGC 4486.

Located in the Virgo constellation, the black hole in M87 is again surprising scientists – this time with a gamma-ray flare that emitted photons billions of times more energetic than those of visible light.
