NGC 6210 is the last gasp of a star slightly
less massive than our Sun at the final stage of its life cycle.
The multiple shells of material ejected by the dying star form a
superposition of structures with different degrees of symmetry,
giving NGC 6210 its odd shape. This sharp image shows the inner
region of this planetary nebula in unprecedented detail, where
the central star is surrounded by a thin, bluish bubble that
reveals a delicate filamentary structure. This bubble is
superposed onto an asymmetric, reddish gas formation where
holes, filaments and pillars are clearly visible.
