Mystery of Galaxy

Welcome back to my blog "Mystery of Galaxy". Today our topic is neutron stars, which are among the strangest and most exotic stars in the universe. In fact, neutron stars really aren't proper stars at all, but instead are the stellar mutant power zombies that began their lives in the death of massive stars. As we know high mass stars evolve and die, the cores of these stars eventually become iron. Since iron can't fuse, it cannot produce the energy needed to hold itself up. For a while it hangs in there, but the pressure is so strong it's squeezed into electron degeneracy. But the core keeps gaining mass, and when it reaches 1.4 solar masses, the electron degeneracy fails and the core implodes. The core collapses from the size of Mars to the size of Manhattan in just a few milliseconds. But during those few milliseconds, protons and electrons are squeezed into each other to become neutrons and neutrinos. The neutrinos escape, but the neutrons are squeezed toge
