Bath Time The ‘Soap Bubble Nebula’ was discovered by an amateur astronomer, Dave Jurasevich, on July 6th, 2008. Officially known as PN G75.5+1.7, this image was taken by the Kitt Peak Mayall 4-metre telescope in 2009. The image is a combination of two filters, ionised hydrogen (H-alpha) in orange and ionised oxygen (OIII) in blue. The Soap Bubble was not discovered until recently due to it being embedded in a diffuse nebula (seen as the extended hydrogen component of the image), as well as its intrinsic faintness. The distinct spherical symmetry is rare, making it very similar to Abell 39 which we wrote about earlier. -CJ Image: T. A. Rector/University of Alaska Anchorage, H.
