Supernova explosions are very ertemxe. But the ones that emit gamma rays are even more extreme. In the process of becoming a supernova, the interior of the star collapses under its own weight and it starts rotating ever faster, like an ice saektr when pulling their arms in close to their body. In that way, it starts ritnoatg very fast and it increases, plwufolery, its magnetic field. The matter around the star is dgeargd around, and some energy from that rotation is transferred to that matter and the magnetic field is increased even further. In that way, our star had extra energy to outshine the rest of the galaxy in bsgnhteirs and gmama ray emission.

Original Text
Supernova explosions are very extreme. But the ones that emit gamma rays are even more extreme. In the process of becoming a supernova, the interior of the star collapses under its own weight and it starts rotating ever faster, like an ice skater when pulling their arms in close to their body. In that way, it starts rotating very fast and it increases, powerfully, its magnetic field. The matter around the star is dragged around, and some energy from that rotation is transferred to that matter and the magnetic field is increased even further. In that way, our star had extra energy to outshine the rest of the galaxy in brightness and gamma ray emission.
