What is a Neutron Star Truth and facts

Universe, we must have seen the stars from time to time. Sometimes small, sometimes big, sometimes bright, sometimes dim. Today we will talk about the smallest star in the universe: Neutron star. 

Neutron star is the smallest in size but the most powerful. A neutron star is a fragment of a normal star formed from a super explosion. whose shape is small but the mass is very high. Such stars are composed entirely of neutrons.

In other words, such a star is formed when a massive star is destroyed, i.e. when a star becomes 5 to 7 times its basic mass, an explosion occurs due to a supernova. As a result, a part breaks off and forms a sphere. 

In which neutrons are produced due to the collision of protons and neutrons due to their own gravity. Such a star is called a neutron star.

A strong force exists between the protons in the nucleus and the orbiting electrons that help keep the two apart, but as the star begins to contract, its gravitational pull becomes much greater. 

There comes a time when the gravitational force becomes greater than the nuclear force and breaks the nuclear force. Due to which protons and electrons together form neutrons. When a star is born, it is not blue in color, over time it becomes red in color and finally it is destroyed and transformed into a neutron star.

A teaspoon of neutron star weighs about the same as a giant mountain on Earth A full neutron star weighs about one and a half times that of the Sun. And its density is 23 billion more than the density of Earth. 

Such a star releases its maximum energy in the form of pulses. Astronomers have named it pulsar. Which was discovered in 1966. The energy released in the form of a pulse was detected on the ground in the form of a signal. 

A neutron star is believed to have the most powerful magnetic field in the universe, if any. Due to which earthquakes keep happening on its surface. It is called starquake. Such an earthquake remains active for 10 thousand years.

The speed of a neutron star is much faster than that of a normal star, but it starts to slow down over time. According to the findings so far, the smallest mass has been found to be 1.3 times more than the mass of the Sun. 

If this mass becomes 2.20 times or more, the star will automatically turn into a black hole. The mass of the neutron stars that astronomers discovered was between 1.3 and 2.11 times that. 

But if the size of the black hole starts to increase, all the neutrons around it will absorb the star into itself. Most of the neutron stars we see are extremely hot, with temperatures up to 600,000 Celsius. That is why they shine.

On December 27, 2004, scientists studied gamma rays from a star named SGR-1806-20 in the constellation Sagittarius Constellation, 50,000 light-years from Earth. Which is considered no bright star till now. It would take about one and a half million years to produce as many gamma rays as the Sun produced in one second.

According to scientists, despite being 50 thousand light years away, it shone like the moon. But if it comes a few light-years closer to our solar system, the entire earth will feel such a jolt that the people there experienced when the nuclear bomb was dropped on Hiroshima. 

But instead of coming close to it, if its gamma rays reach the earth, not a single organism will be left on the earth, besides this, such a terrible situation can be created such as tsunami, ozone layer break, volcano eruption, glacier break. 

And if it enters the solar system, the entire solar system will be disintegrated in an instant. All planets due to their different rotation and revolution will leave their orbit and collide with each other causing destruction. But will any living creature survive to see all this?
