Summary:
- Astronomers have observed a massive star explosion, known as a supernova, that released a powerful coronal mass ejection (CME) - a huge cloud of solar plasma and magnetic fields.
- This event, known as a "super-CME," is extremely rare and provides valuable insights into the violent processes that can occur during the final stages of a star's life.
- The energy released by this super-CME is equivalent to the output of our Sun over several million years, demonstrating the immense power of these cosmic events.
