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.
The eye of god is a Helix nebula. Close to a Planetary nebula.
Considering the size of the Milky Way Galaxy and the amount of "empty" space, the amount of space an emission nebula occupies is so small as to be infinitesimal and impossible to equate to a volume.
Not much other than that they both emit light in large quantities.A nebula is a grouping of billions of stars, while a supernova is a single star exploding at a stage in its development.Comments: That meaning of "nebula" as a galaxy (or a star cluster within a galaxy) is a bit out of date now. Nowadays a nebula usually means a cloud of gas and dust. It doesn't usually emit much light.Actually there is a connection between a supernova and a nebula.Some of the stuff found in nebulae comes from supernova explosions.
Nebula was played by Karen Gillan. She is best known for her role as Amy Pond in the Doctor Who series.
You might be asking about the Milky Way, the part of the sky where we are looking through the edge of our galaxy.
Considering the distance to the Cats Eye Nebula is only 3,300 light years away, it is going to be within our own Milky Way Galaxy.

The Cats's Eye Nebula is a perfect example of a planetary nebula. See related link for a pictorial.
Earth is IN a galaxy - as is the nebula.
A Galaxy is far bigger than a nebula.
A nebula galaxy does not exist.
The Andromeda Nebula, now known as the Andromeda Galaxy, has no discoverer as it is visible to the naked eye. The idea that it was a galaxy and not a nebular was fist proposed in 1917 by Heber Curtis and proven in 1925 by Edwin Hubble.
According to Wikipedia: Radius Core: 0.2 ly
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.
The eye of god is a Helix nebula. Close to a Planetary nebula.
Not "a" - it's the name of one specific planetary nebula. You can find pictures of it in Google Images.
Yes. A nebula is just a big gas cloud. A galaxy will contain many nebulas.
