The central region of a planetary nebula is shown in a box. Labels indicate “Shock waves”, “Outflow collisions”, and an “Ionised jet” in the dust on both sides of the nebula. Close to the centre, “Dusty torus” and “Ionised torus” are marked. In the very middle, a faint dot inside a blotchy pink cloud is labelled “Dying star”. Bright stars surround the nebula and can be seen through the dust layers.
