The globular cluster (GC) system of our Galaxy contains four planetary nebulae (PNe): K 648 (or Ps 1) in M15, IRAS 18333-2357 in M22, JaFu 1 in Pal 6, and JaFu 2 in NGC 6441. Because single-star evolution at the low stellar mass of present-epoch GCs

The WFPC2 camera aboard the HST was used to obtain images of the planetary nebula BD+30 3639 at two epochs separated by 5.663 years. The expansion of the nebula in the H-alpha and [N II] bands has been measured using several methods. Detailed expansi

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
