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
[edit ]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, it was difficult to discover.[8]
