Crab Nebula

When the crab nebula looks up at the night sky, you can see the stars lie on top of an endless black blanket. New stars are formed in this "blanket" called interstellar medium. The interstellar medium consists of 99% of gas and about 1% of dust particles. Hydrogen is a main gas in the form of atoms and molecules. As the place where the star was born, the interstellar medium also produces a beautiful nebula. A reflective nebula is created when light from nearby stars is reflected from dust particles in the interstellar medium.

The crab nebula is "the key to understanding the death of a mass star and its substance". I will understand what happens to the stars that astronomers explode by studying crab nebulae and other supernovae (sailing in the universe). For example, the explosion is only 50 light years away from the earth, and astronomers believe that all creatures on the earth will die of radiation.

Since 1054 BC many mysteries of the crab nebula have been revealed by the contributions of many astronomers and physicists. At first it was a new celestial body in the sky, but told the existence of wise and gentle individuals, misplaced comets and experienced various phenomena before astronomers came. Checking the nebula at the conclusion of modern theories and assumptions provides a rich journey through the history of astronomy

Crab Nebula is the latest and most attractive supernova remnant. In 1054, the stars of Taurus exploded in the supernova (star violent death), so it took more than a year in the night sky. (History of Crab Nebula) This nebula is composed of substances that are released from a supernova explosion with a diameter of 10 light-years and are currently expanding at a rate of 1800 km / s. (Major Object 1) Chinese astronomer discovered on July 4, 1040 that it is "a star of customers". And it is 4 to 6 times brighter than Venus. It is nearly 6500 light years away from us and the diameter is 6 light years, which can be seen during the day for 23 days and at night for 653 days. "Chinese astronomers express this star as sharp red-white on all sides" (Messier object 1)
