The Soap Bubble nebula (PN G75.5+1.7) is a planetary nebula near the Crescent nebula (NGC6888) in the constellation Cygnus. The soap bubble is in the bottom left quadrant of the image. This bubble of ionized gas was ejected from a red giant - something that the Sun will eventually do. As this nebula is very faint and is surrounded by other diffuse nebulosity, it is difficult to image and spot. It was discovered recently in 2008. #astrophotography
