One thing you really notice is the complex, feathery, knotty structure of the gas and dust in our galaxy. If you look around, you can see a couple more objects that might be good candidates for being other galaxies with their own star-forming regions. What are these objects called

Orion Nebula & cone nebula

Explanation:

From the huge, youthful stars that are forming the nebula to the pillars of thick gas that could be the homes of burgeoning stars, the Orion Nebula is a picture book of star formation. The four heaviest stars in the nebula reside in the bright central field. Since the stars are arranged in a trapezoid shape, they are known as the Trapezium.

These stars' ultraviolet radiation is cutting a hole in the nebula and stars that are already young enough to have disks of material encircling them can be seen near the Trapezium stars. Protoplanetary disks, also known as (proplyds) are too small to be seen distinctly and the disks are the foundation of solar systems.

The Cone Nebula is a monstrous creation, which resembles a nightmare beast flaring up from a crimson sea, is simply a benevolent pillar of gas and ashes. The Cone Nebula is so identified because it has a conical appearance in ground-based photographs. This massive pillar is located in a tumultuous star-forming area with gnarled mountainpeak of cold gas and dust is visible.

this is a good question! i'll do some research and come back when i have the answer!
