Summary:
- Astronomers have discovered the biggest explosion ever observed in the universe, which occurred in a galaxy cluster about 390 million light-years from Earth.
- This explosion was caused by a supermassive black hole at the center of the galaxy cluster, which released an enormous amount of energy equivalent to hundreds of millions of supernova explosions.
- The discovery of this record-breaking explosion provides new insights into the powerful processes that can occur in the centers of galaxy clusters and the role of supermassive black holes in shaping the evolution of the universe.
