Brief introduction of Orion nebula

The Great Orion Nebula (M42, NGC 1976) is a reflection nebula and a diffusion nebula located in Orion. 1656 was discovered by the Dutch astronomer huygens, with a diameter of about 16 light years, an apparent magnitude of 4, and a distance of 1500 light years from the earth. The same position is also near the star name of China. Orion Nebula is a huge cloud of gas and dust, which is producing new stars in space. Through telescope observation, we can see that the Orion Nebula is shaped like a big bird spreading its wings, and its brightness is quite high, which is second only to the Callina Nebula in the whole day. It can be observed with naked eyes in areas without light damage. Orion nebula is the brightest gas nebula in the whole day.
