What kind of nebula is Orion nebula?

Let's see what kind of nebula Orion is. Orion Nebula Orion Nebula (M42, NGC 1976) is a reflection nebula and a diffusion nebula located in Orion. It was discovered by the Dutch astronomer Huygens in 1656. It has 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. The nebula features the Orion nebula, which has three bright stars arranged neatly and three small stars arranged obliquely. Without a telescope, you can see that one of the three small stars is faintly glowing red. It is not a star, but the Orion nebula. It is a luminous gas cloud in Orion, which can be directly observed in the middle of Orion sword. The nebula is connected with a star-forming region and illuminated by the young stars it contains, which is very spectacular in astronomical photos. The Orion Nebula is also one of the indicators to identify Orion. The square star in the center of the nebula is one of the targets for observing and studying the birth of stars, and photographing the details of the nearby nebula is also the object to test astrophotography, telescope resolution and post-processing kung fu. Orion Nebula is an X-ray source, which contains some Herbig arrow objects, a pulse source and some T-shaped Taurus stars. Because it is close to the earth, the Orion Nebula is one of the most thoroughly studied celestial bodies.
