Long description

The figure consists of four parts labelled (a) to (d) that illustrate images of different astronomical sources. Part (a): Image of the nebula NGC 6302 with left and right lobes of a central star. Part (b): The multipolar planetary nebula NGC 6543 with two axes of symmetry and a blue cloud at the centre of a reddish brown cloud at the intersection of the axes. Part (c): A composite view of the AGB star L2 Puppis in the visible light (blue). A red giant is seen as a yellow dot at the centre between top and bottom light regions labelled ‘plume’. On the left of the red giant is a small reddish patch. On the right of the red giant is a larger bright orange patch labelled ‘ALMA candidate planet’. Part (d): A reddish brown spiral in the material around the AGB star R Sculptoris, as viewed tunnelling through the spiral.
