The Carina Nebula is an example of a diffuse nebula. Most nebulae can be described as diffuse nebulae, which means that they are extended and contain no well-defined boundaries. [24] Diffuse nebulae can be divided into emission nebulae, reflection nebulae and dark nebulae.
The Messier catalogue comprises nearly all of the most spectacular examples of the five types of deep-sky object – diffuse nebulae, planetary nebulae, open clusters, globular clusters, and galaxies – visible from European latitudes. Furthermore, almost all of the Messier objects are among the closest to Earth in their respective classes ...

It is referred to as the Northern Trifid because of its similar appearance to the Trifid Nebula, which is located in the southern celestial hemisphere of the sky. It is a H II region, a region of star formation. [4] The star cluster contains the emission-line star LkHα 101, which provides much of the ionizing radiation in the nebula. [5]
