A gas nebula powered by a Wolf-Rayet star in the center. The star has ejected several times the mass of the sun into the surrounding gas remaining from the formation of the star only several million years ago. The star is more than 20 times as massive as the sun and has almost burned its fuel. In about a million years from now it will go supernova providing a spectacular firework.

Also visible on this image is PN G75.5+1.7 or Soap Bubble Nebula. It is a Planetary Nebula of a more gently dying star. Interesting fact is that is was only recently discovered by an amateur astronomer in 2007/2008.

Some cropped versions of the above image show it more clearly. It is on the bottom a bit to the right.
