The Calabash Nebula is a protoplanetary nebula 1.4 light years long and located approximately 5,000 light years from Earth. It is sometimes called the Rotten Egg Nebula because it contains a relatively large amount of sulfur. The densest parts of the nebula are composed of material ejected recently by the central star and accelerated in opposite directions at incredibly high speeds. What do astronomers believe will happen to the Calabash Nebula 1,000 years from now? Discuss
