||The extremely bright and concentrated globular cluster, M15, is home
to a unique planetary nebula called Pease 1. As shown in the bottom image,
a typical groundbased (amateur) image can just barely discern the color
of the shell of this dying star. The inset Hubble Space Telescope image
easily resolves the nebula and stars it the field. A triangle of three
stars that are represented in both images are labeled for easier comparison.
M15 is one of three globular clusters known to harbour a planetary nebula.
