A selection of Hubble’s planetary nebulae

This mosaic shows a selection of stunning images of bipolar planetary nebulae taken by Hubble.

A new study using Hubble observations has found that bipolar planetary nebulae located towards the central bulge of our Milky Way appear to be strangely aligned in the sky — a surprising result given their varied histories. The nebulae shown here were not involved in this new study, but demonstrate the varied forms of these spectacular objects.
