Summary:

- Astronomers have detected an enormous explosion from the supermassive black hole at the center of the galaxy Messier 87 (M87), which was the first black hole ever photographed.
- The explosion, known as a jet, is believed to have been caused by a massive flare of energy and material being ejected from the accretion disk around the black hole at nearly the speed of light.
- This discovery provides new insights into the extreme physics and energetic processes occurring around supermassive black holes, which play a crucial role in the evolution of galaxies.
