No, we believe that nebulae probably exist in every galaxy, and possibly between galaxies as well.
No. Nebulae exist in almost every galaxy.
Nebulae can exist both within and outside of our galaxy, the Milky Way. Nebulae are vast clouds of dust, gas, and plasma in space where stars can form. They are found in many different galaxies throughout the universe.
No, nebulae are not unique to the Milky Way, there are hundreds that have been identified outside it, and are generally assumed to be present in most if not all other galaxies.
no
Galaxy exists because stars and nebulae exists.
The types of nebulae that exist in the universe include bright, dark and emission nebulae. Different nebulae are often named for their shape. More information can be found on "Sea and Sky".
Yes. There are many planetary nebulae in our galaxy.
Ionization nebulae in the galaxy M51 are predominantly located in the spiral arms of the galaxy. These regions are where massive, young stars are found, which emit high-energy ultraviolet radiation that ionizes the surrounding gas, creating the colorful nebulae. The ionization nebulae are often observed in regions of active star formation within the galaxy.
within or on the edges of the spiral arms of the galaxy
If you look it up, you will see that the distance from Earth is estimated at 3300 light-years (with an error estimate of 900 light-years). This is well within our own galaxy (the Milky Way), which has a diameter of about 100,000 light-years.Pressumably, nebulae exist in other galaxies, but the more well-known nebulae are in our own galaxy, because, being closer, we can observe them best.

Nebulae are found in most galaxies
