Messier 76 is a beautiful and dramatic looking planetary nebula living in the magnificent, far-northern constellation of Perseus. Planetary nebulae are the short-lived end-point in the lives of Sun-like stars, their outer layers expelled with the hot core exposed as an ever-cooling white dwarf remnant, its strong ultraviolet radiation ionising the tenuous surrounding envelope and producing an incredible variety of beautiful nebulae. M76’s hourglass figure Messier 76 exhibits a remarkable bi-polar structure in deep images, a central, brighter area that has been variously coined a ‘box’, a ‘cork’ or
