The Soap Bubble Nebula is a planetary nebula discovered as recently as July 2008. David Jurasevich first and, independently, Helm and Quatrocchi a few days later, imaged this area, close to NGC 6888, the Crescent Nebula, and reported to the IAU, the presence of an uncatalogued nebula.
This nebula has not yet been the subject of much research and is similar, in visual structure, to other simple (but beautiful) planetary nebulae like Abell 39, Abell 33 or even the very faint Pre-8. The central star responsible of the formation of this nebula can be seen in the cropped image below. Its magnitude has not been published (it seems to be around mag +21) and it has been enhanced in order to appear in the image.
