NGC 6894
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. Furthermore, 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!
