The pulsar, a neutron star emitting a focused
beam of electromagnetic radiation.
This radiation is only visible when you are
standing in its path.
These pulsating pulsars are the dead relics
of massive stars.
They are highly magnetized and rotates at
enormous speeds.
They are detected by the radio pulses they
emit at regular intervals.
So how these pulsars are formed?
When a star having mass 4 to 8 times the mass
of our Sun goes Supernova,
the outer layers are blasted off into space,
and the inner core contracts down with
its gravity.
The gravitational pressure is so strong that
it overcomes the bonds that
keep atoms apart.
Electrons and protons are crushed together
by gravity to form neutrons.
The surface gravity of neutron star is about
200 billion the times of Earth.
So, the most massive stars detonate as supernovae,
and can explode or collapse into black holes.
