This planet's magnetic field is 10,000 times stronger than Earth's, so it traps huge amounts of particles and supercharges them, meaning that the radiation levels around Jupiter are about what you'd get near a nuclear explosion.

这颗行星场强度是地球 1 万倍,所以它捕获了大量粒子并对它们增压,这意味着木星周围辐射水平与核爆炸附近水平相当。

But when that core collapses, the strength of the field skyrockets, and a neutron star can easily have a magnetic field several trillion times stronger than the Sun's.

但当其核心坍缩时,它们磁场强度会急剧上升,一颗中子星磁场很轻易就会比太阳强几万亿倍。
