A magnetar is a type of neutron star with an extremely powerful magnetic field. These fields are trillions of times stronger than Earth's. They can emit bursts of high-energy radiation, like X-rays and gamma rays. Magnetars form from the core collapse of massive stars during supernova explosions. Think of them as cosmic dynamos, generating insane magnetic forces. Their intense magnetism can cause starquakes on the surface. They are relatively rare but fascinating objects in the universe.
