Cosmic tower - Neutron star

In 1967, astronomers suddenly received a strange electric wave. This electric wave is played once every 1-2 seconds, just like the pulse of a human. It was thought to be the call of the universe, the shocking moment. Later, British scientist Anthony Hewish clarified what that electromagnetic wave was. It is an electrical wave emitted from a special unknown crystal that was previously unknown, known as pulsed pulse (Pulsars). This discovery led him to receive the Nobel Prize in Physics in 1974.

Currently, 300 pulse pulses have been detected. They are all in the Milky Way system. The Crab Nebula Center also has a pulse pulse.

Pulse pulse is one of the four major astronomical findings of the 60s (stellar, star organic molecules and 3K microwave radiation of the universe are the remaining two discoveries). The pulse circuit from that is continuous and intermittent is very stable, the time accuracy is no less than the electronic clock. The cycle is different for each star, up to 3.7 seconds long; Short is only 0.033 seconds.

Pulse star is a self-rotating neutron star . Neutron stars are very small, the diameter is usually only about 10km, but the weight is equal to the Sun, which is the heavy crystalline density is higher than the proportion of white dwarfs.

The neutron star's predecessor is usually a larger planet than the Sun. In the process of pressing the explosion has produced great pressure making its physical structure change completely. Not only was the broken atomic shell broken, the proton and neutron pressed together, protons and electrons pressed together into neutrons. Eventually neutrons pressed together to turn into neutron stars. On neutron stars, each 1cm3 mass of material weighs 1 billion tons.

After crystallization shrinks and turns neutron stars, the speed of rotation automatically increases, every second from several rounds to dozens of rings. Why does the neutron turn into a powerful "magnet" , a part of the "magnet"

broadcast out. When it turns itself at such a great speed, like a lighthouse tower, sweeping the electric wave toward the Earth in a regular and continuous way. When the broadcast unit turns toward Earth, we get the signal, when that part rotates away from the star itself, we don't get the signal. The electric wave we have obtained has a pause, this phenomenon is called "light tower effect".

The solar energy of neutron stars is 1 million times that of the Sun. Its total radiation energy in 1 second if converted into electricity is enough for Earth to use for several billion years.

Neutron stars are not the final state of crystallization, it will continue. Because of the very high temperatures, energy consumption is also fast, so its lifespan is only a few hundred million years. When its energy is depleted, neutron stars will become non-glowing black dwarfs.
