Is the Orion Nebula part of the Milky Way? How far is it from us?

The Orion Nebula (M42) is a nebula in the Milky Way. It is about 1,500 light-years away from the Earth. It is located on the Orion cantilever of the Milky Way. It has a diameter of 16 light-years and is nurturing many young stars.

The Orion Nebula

The Orion Nebula is a huge luminous gas cloud. It ranks 42nd on Messier’s list of celestial objects, so it is also called M42. In telescopes , the Orion Nebula is like a bird with spread wings. It is also the brightest nebula in the sky and can be seen with the naked eye in places without light pollution.

As shown in the picture above, the brightest part of the circle looks like a star to the naked eye. In fact, it is not a star. After observing with a telescope, we can see that it is actually a nebula. It is the Great Nebula in the constellation Orion, with apparent magnitude 4.

The picture below is a photo of the Orion Nebula taken by the Hubble Telescope on November 29, 2017. You can see that there are many filamentous structures in the nebula. These are luminous points in the nebula formed by shock waves. They are young stars, many only about 1 million years old.

In the Orion Nebula, there are thousands of young stars and dense clouds that are about to become stars. These stars emit intense radiation and are then absorbed by the surrounding interstellar gas. These interstellar gases then Radiating energy in the form of visible light forms the Orion Nebula we see.

Horsehead Nebula

There is a protruding cloud in the Orion Nebula. This is the famous Horsehead Nebula. It is named because it looks like a horse's head when viewed from Earth. ?Horsehead?is about 1 light-year tall.

The Horsehead Nebula is a dark nebula that is set off by the bright nebulae around it. In the Horsehead Nebula, the brighter points are newly formed stars, which may be only a few hundred thousand years old.
