Near the end of their lives, stars like the sun blow off a cloud of gas. Radiation from the star makes the gas emit light and form a beautiful glowing cloud called a planetary nebula. We'll see how slides and demonstrations can be effectively used to show why planetary nebulae glow in different colors and have the strange variety of shapes that are observed. There are interesting puzzles about planetary nebulae that make them topics of current research. We’ll discuss some of these puzzles and understand how modern technology (and, perhaps, you) will help provide answers.
