Sitting in a rich field of OIII and Halpha emission nebulae, a remarkable and beautiful, striated, teal coloured,
almost perfectly spherical, bubble, is being blown in the interstellar medium by the intense stellar wind from a
very hot and massive Wolf-Rayet star at its centre. Wolf-Rayet stars have surface temperatures of between 30 000K
and 210 000 K, compared to our Sun, which has a surface temperature of just 5800K!
