Where is the centre of the Egg Nebula? Like a baby chick pecking its way out of an egg, the star in the centre of the Egg Nebula is casting away shells of gas and dust as it slowly transforms itself into a white dwarf star. The Egg Nebula is a rapidly evolving pre-planetary nebula spanning about one light year towards the constellation of Cygnus. Measuring the orientation of the polarised light for the Egg Nebula gives clues as to location of the hidden source. The image taken by the Advanced Camera for Surveys on the Hubble Space Telescope is false-colour coded to highlight the orientation of polarisation.
