||NGC 6894 is a seemingly typical planetary nebula. It has a diffuse
spherical outer shell with a more convoluted inner structure. The overall
pinkish color to this nebula may be due to the reddening of light caused
by intervening clouds of gas and dust in this direction. This nebula also
has a unique attribute- in deep images (not shown here) this nebula may be
interacting with the local interstellar medium (latent galactic gas clouds). Notice
that the top left quadrant of the nebula has an oval bright area. This
could be a symptom of this interaction. Futhermore, these deep images
reveal that the gas released from this nebula has aligned itself with the local
magnetic field of the galaxy. These observations help to probe the nature of
our galaxy 4000 light years away!
