The Soap Bubble Nebula, Ju 1 (also known as PN G075.5+01.7) is a planetary nebula in the constellation Cygnus, [4] near the Crescent Nebula (NGC 6888). The nebula derives its name from its symmetrical spherical shape which resembles a soap bubble. [5]
Discovery
It was discovered by amateur astronomer Dave Jurasevich using an Astro-Physics 160 mm refractor telescope with which he imaged the nebula on June 19, 2007 and on July 6, 2008. [6] The nebula was later independently noted and reported to the International Astronomical Union by Keith B. Quattrocchi and Mel Helm who imaged PN G75.5+1.7 on July 17, 2008. [7] The nebula measures 260 ″ in angular diameter with a central star that has a J band magnitude of 19.45. [2]
Due to the faintness of the nebula and the fact that it is embedded in a diffuse nebula, this made the diffuse nebula hard to discover. [8]
