[SIZE="2"]What does Holy Quran says about the pulsar![/SIZE]
A
pulsar is a highly magnetized neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth, in the same manner as the beam from a lighthouse causes flashes. Being enormous cosmic flywheels with a tick attached, they make some of the best clocks known to mankind.
Pulsars originate when an old, massive star explodes as a supernova. In this process, the core of the star implodes. The core collapses through the white dwarf stage until its constituent protons and electrons combine to form neutrons. If it is not too massive (less than 1.4 times the mass of the Sun) it can stabilize at this point as a very hot, incredibly dense ball of neutrons with a thin crust of ordinary matter on its surface. Neutron stars are spinning rapidly when they form - up to about 800 and even one thousand rotations per second - and slow down as they age. These pulses of the pulsar are reminiscent of heart-beats or someone's knocking quickly at door.
The word "pulsar" comes from the verb to pulse. According to the American Heritage Dictionary, the word means to pulsate, to beat. Encarta Dictionary defines it as to beat rhythmically, to move or throb with a strong regular rhythm. Again, according to the Encarta Dictionary, the word "pulsate," which comes from the same root, means to expand and contract with a strong regular beat.
Following that discovery, it was realised that the phenomenon described in the Qur'an as "tariq," beating, bore a great similarity to the neutron stars known as pulsars
The Holy Quran mentions the pulsar by one of its most outstanding features ; Read the following verse from the Holy Quran :
Allah (God) says in the Holy Quran:

"I swear by Heaven and the Tariq ( The Knocker ) ! And what will convey to you what the Tariq is? The Star Piercing [the darkness]!"
[Quran, 86:1-3][/SIZE]
The word ( Tarek and the word Al-thakeb ) are two different Arabic words that are used in the above-mentioned verse to describe the Pulsar , the word Altarek means in English " the Knocker or that beats quickly and the word " Al-thakeb" means " piercing ", these two characteristics ( knocker and piercing ) are one of the most specific features of pulsar .
Allah (God) in the above mentioned verse , though He needn't swear , Did swear by that star.when God swears , he swears by something great and also what He swear on is assuredly great.
The word "Tariq," name of the Sura 86, comes from the Arabic root "tarq," whose basic meaning is that of striking hard enough to produce a sound, or hitting. Bearing in mind the word's possible meaning as "beating," "striking hard," our attention may be being drawn in this sura to an important scientific fact. Before analysing this information, let us look at the other words employed in the verse to describe these stars. The term "al-taariqi" in the above verse means a star that pierces the night, that pierces the darkness, born at night, piercing and moving on, beating, striking, or sharp star. Furthermore, the term "wa" draws attention to the things being sworn on-the heaven and the Tariq.
In the third verse of Surat at-Tariq the term "al-najmu al-thaaqibu," meaning piercing, moving on, or opening holes, indicates that Tariq is a bright star that pierces a hole in the darkness and moves on. The concept of the term "adraaka" in the expression "And what will convey to you what the Tariq is?" refers to comprehension. Pulsars, formed through the compression of stars several times the size of the Sun, are among those celestial bodies that are hard to comprehend. The question in the verse emphasizes how hard it is to comprehend this beating star. (Allah knows best.)

These sounds are from the brightest pulsars in the sky, recorded using some of the largest radiotelescopes in the world.
