Pulsars are neutron stars born in the aftermath of a supernova explosion. When a massive star exhausts its nuclear fuel and collapses under gravity, it undergoes a supernova explosion. This violent event ejects the outer layers of the star into space, while the inner core collapses further, forming a neutron star. If this neutron star rotates rapidly and has a strong magnetic field, it emits beams of radiation that can be detected as pulsating signals, hence the term "pulsar." Therefore, pulsars are directly linked to supernovas as the remnants of massive stars that have undergone gravitational collapse and explosion.
