Summary:
- Astronomers have discovered the power source behind some of the brightest supernovae in the universe. These supernovae are called "superluminous" supernovae.
- The power source is believed to be the rapid spin of a magnetized neutron star, also known as a magnetar, at the center of the supernova. The magnetar's intense magnetic field and rapid rotation produce a large amount of energy that powers the supernova.
- This discovery helps explain the extreme brightness of these supernovae, which can outshine entire galaxies for a period of time. Understanding the mechanisms behind these supernovae provides valuable insights into the life cycle of stars and the formation of heavy elements in the universe.
