Searching for Jets in Asymmetrical Nebulae with the Hubble Space Telescope

The jets seen in NGC 6543 motivated us to search for similar features in other PNe. Our HST snapshot program looked for jets using the [N II] and H-alpha narrow-band filters. Although spectacular jets are found in proto-PNe, true jets seem rare among mature PNe. In the later group, IC 4593 is the best case in our sample. We distinguish between jets and a number of interesting ``jet-like'' features, e.g., ``cometary'' structures with a dense globule at the end facing the central star.
