Neutron Stars: Crash Course Astronomy #32
In the aftermath of an 8-20 solar mass star’s demise, we find a weird little object known as a neutron star. Neutron stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars, flashing in brightness as they spin. Neutron stars with the strongest magnetic fields are called magnetars and are capable of colossal bursts of energy that can be detected over vast distances.
