Planetary Nebula NGC 6210

The remarkable features of this nebula are the numerous holes in the inner shells with jets of material streaming from them. These jets produce column-shaped features that are mirrored in the opposite direction. The multiple shells of material ejected by the dying star give this planetary nebula its odd form. In the 'full nebula' image, the brighter central region looks like a 'nautilus shell'; the fainter outer structure (colored red) a 'tortoise.' The dying star is the white dot in the center.
