The "Cygnus Bubble" nebula may actually be a cylinder that is being seen from one of its ends. This image was taken with the Kitt Peak Mayall 4-metre telescope in Arizona (Image: Travis A. Rector/U of Alaska Anchorage/Heidi Schweiker/NOAO)]

IT LOOKS like a soap bubble or perhaps even a camera fault, but the image at right is a newly discovered planetary nebula. [...] The bubble, which was officially named PN G75.5+1.7 last week, has been there a while. [...] "It's a beautiful example," says Adam Frank of the University of Rochester, New York. "Spherical ones are very rare." One explanation is that the image is looking down the throat of a typical cylindrical nebula. However, it is still remarkably symmetrical, Frank says.
