Constellation characteristics of Orion nebula

The Orion Nebula is about 400 parsec (about 65,438+0,500 light years) away from the Earth, and it is part of a huge molecular cloud outlined by Orion that covers almost the whole sky. Some of the densest parts of the nebula absorb visible light and can only be observed by infrared or radio methods. These dense areas include hot spots related to the birth of stars. There are some stars in the nebula, which are only 654.38+0 million years old. They emit strong ultraviolet radiation, which is absorbed by the gas in the nebula and re-radiated in the form of visible light, thus making the nebula bright. The luminous part of the nebula is an ionization region.

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 very close to us, the Orion Nebula is one of the most thoroughly studied celestial bodies.
