Neutron stars are astronomical objects celestial objects that exist in the observable universe. Basically neutron stars are the  remnants of giant stars like our sun will be, that died in a supernova explosion, after the explosion the Cores of these  stars compact into a extremely dense or a ultra-dense object with the mass of 1.4 times the mass of the Sun, but neutron stars are not much bigger then a size of a small city. But if you know that a teaspoon of neutron stars would weight about millions of tones. The gravitational field of neutron stars is very intense.

In today's time humans have made many discoveries about stars and also doing but this was not done before. The ancient people believe that stars never change and the astrologist of that time thinks that stars are immortal and never dies. But this is not true with the passage of time we found that every star has a lifetime in which they born and spend their lives and after which they dies. The death of this stars basically depends on their mass; extremely less mass stars dies the form of white dwarf and stars with extremely high mass dies in the form of black hole. But the stars having mass between white dwarf and black hole dies in the form of neutron stars.

How stars produce energy:


The Star produce energy with the help of of nuclear fusion, nuclear fusion is the process in which two hydrogen atom combine to form one Helium atom, in this process a lot of of heat is produced which helps stars to burn. This energy keeps coming continuously from the core of stars to the surface of the stars. In the centre of star (core) firstly hydrogen convert into helium. If stars are large and dense then Helium atoms convert into carbon and carbon's fusion into neon and neon into oxygen and oxygen's fusion into silicon and silicon into iron; after that nuclear fusion of iron is not 
possible. When the fuel of these stars exhausted, these stars do not handle themselves against their own mass and with a big explosion, this stars collapsed in their own centre. This explosion is also known as supernova
explosion. After this explosion the size of these stars sarts to shrink very rapidly and in the last these stars size changes to the size of an object of 25 kilometers in diameter but their mass is three times more than the mass of sun. These stars are very dense and their gravitational force is around 2000 billion times of Earth also 2×1011 times stronger than on Earth. According to law of conservation of angular momentum These stars revolve at a very high speed. Rotating at such a high 
speed, these stars form a strong electro-magnetic field and radiation continuously emanates from these stars. Because of which we see them blinking from the earth. Due to this blinking effect of these stars, they are also called Pulsars. After several million years, the energy of 
these pulsars dissipate and these stars become normal neutron stars. There are about 1000+ pulsars present in this universe. It was Dr Fritz Zwicky and Walter Baade Fizikus 
who first ever told about the origin of neutron star after supernova.The first neutron star was discovered in 1932 and calvera is the nearest neutron star to earth and it is situated in ursa minor constellation and it is about 250-1000 light years far from us. The the neutrons stars stars which is in front of our Earth is PSR-J0108-14831 which is 250 light years far from us.

So it is enough for now, hope you find it interesting and may you get some information about neutron stars and we will make more posts about neutron stars and our space and universe.
