The missing neutron star had found


    We know that many unidentified objects in the sky. Scientists are doing various experiments to find them at that time we talked about their discoveries. We can feel proud of these scientists because they have super minds. They are thinking differently than we think. It is true. If it is wrong, we all have to think of making spacecraft and travel to space. We know that they invented many things and discovered many things until now. Today I have to tell you about a discovery. This is depicted through the topic itself. This had missed for about 30 years, but now they have found it. 

  Do you know what a neutron star is? 

  Neutron Star 

Today I would like to talk about a neutron star. These are a type of small star. Neutron stars have a radius of about 10 kilometres, and mass is about 1.4 solar mass. A neutron star is a collapsed core of a giant star. Before collapsing it has a mass of approximately about 10^29 solar masses. In other than that this is a result of a supernova explosion of a star. 

  Now it is time to know some details about the supernova explosion.

Supernova Explosion 

This is an explosion of stars. This occurs at the end of a star’s life cycle. It is a type of massive explosion that takes place in the space. Scientists had discovered that type II could do damage to the ozone layer of the Earth. I think you have got more details about the supernova explosion. We will move to our main topic. 

      We can get some rough idea about the matter inside it through the name. This is a neutron star. So there have to be neutrons inside this star. What are those neutrons? 


 You know that there are subatomic particles inside matter. Neutrons are subatomic particles. Electrons and protons are some other subatomic particles. These particles are known as neutrons because they are neutral. They haven’t any electrical charge. As well as that they are more massive than the protons. The combination of protons and electrons produce the neutrons. 

 Properties of a neutron star 

A neutron star has a very high temperature of about 600 000 K. Therefore neutron stars are scorching. The magnetic field in it is more potent than about between 108 and 1015 as in the Earth’s magnetic field. The gravitational field of a star is greater than the gravitational field of a neutron star is about 2×10^11. There the matter inside it is very dense. As well as that usually newly formed neutron stars rotate a hundred times per one second. Some of the neutron stars emit light. It is not a light it is electromagnetic radiation. I told you some rough details, but now I would like to explain one by one to you. 


  Tolmen – Oppenheimer-Volkoff is the upper limit of the mass of a neutron star. Usually, it is about 2.2 solar mass. The lowest mass is about 1.1 solar mass.


  Approximately temperature is about 10^11 to 10^12kelvin. There is a classification of neutron stars according to their mass and the heat. In Type I – neutron stars with low mass and cooling rates

Type II- neutron stars with higher mass and cooling rates

Type III – neutrons with higher mass and with higher cooling rates. 


  The density of a star is about 3.7 ×10^17 to 5.9×10^17 kg/m^3. Neutron stars are so dense that one teaspoon of matter inside the neutron star is about 5.5×10^12 of mass. That is equivalent to 900 times about the pyramid of Giza. 

Gravitational field

  One teaspoon is about 1.1×10^25 N weight. 


 The pressure of a neutron star about 3.2×10^31 to 1.6×10^34 Pa. This pressure increases from the inner crust to the centre. 

Magnetic field

 The magnetic field is powerful about 10^4 to 10^11 Tesla. There is another name for neutron stars because of this powerful magnetic field. It is the magnetars. Magnetars have a range between 10 8 and 10^11 tesla. 

 Do you know that Antony Hewish and Jocelyn Bell Burnell had observed those radiations first? Yes, they are the people. They discovered there is a type of stars as neutron stars. 

 Do you know the fastest spinning neutron star? It is PSR J 17482446ad. It revolves 716 times per second. There are about 100 million about neutron stars in the Milky Way galaxy. But the detection of them is not easy. Through the Hubble Space Telescope, there can be identified that the stars that emit thermal radiation. Through the gravitational waves, even it can be detracted. 

  I told you about many details about what is a neutron star. Finally, I would like to say some examples of neutron stars. They are as follows. 

● PSR J0108-1431

● Black widow pulsar 

● LGM-1

● The magnificent seven 

● PSR B1257+12

Now I am sure you won’t create any doubt about neutron stars ever.


You know that my topic is about a neutron star that had found after 30 years. This was a hidden star for the past 30 years. But recently the Cardiff University team had seen this neutron star. You know that we can see only after a supernova explosion. The supernova is known as 1987A. It was named like that because it was first observed on the 23rd of February 1987. This is 160,000 light-years far away from the Earth. 

 Scientists of Cardiff University longed to see like this neutron star for the last few years. Now their dream had fulfilled. It is visible through this saying.

“for the first time, we can tell that there is a neutron star inside this cloud within the supernova remnant “. Dr Phil Cigan said this from Cardiff University. He is the lead author of the study. 

 Now they are trying to find more on this star. Scientists can quickly identify a place that a neutron star is placed. Do you know-how is that? One part of the cloud appears brighter than the elements around it. It is evidence that can find a neutron star around those clouds. 

 Now you know that the details about a missed neutrons for 30 years. I am sure that scientists found more secrets of space some more in the future. Therefore keep alert.
