A neutron star remains as the last trace of a star’s existence after it dies and goes supernova, resulting in a tremendous explosion. One of those neutron stars would be referred to be a magnetar if its extremely powerful magnetic field and extremely dense core were combined.

In addition to being magnetic stars, magnetars are the strongest magnetic stars in the entire universe, with magnetic fields over a trillion times stronger than Earth’s. Moreover, magnetars are tiny. Their masses are nearly twice as large as the Sun’s, even though they are only 20 miles across.
