Sugar Candy Nebula is a protoplanetary nebula associated with a star that is at the stage after the asymptotic branch of giants . [2] The protoplanetary nebula is an astronomical object at such a stage of stellar evolution, in which the star begins to drop outer layers and gradually passes to the stage of planetary nebula . First observed by the IRAS spacecraft. IRAS was launched in January 1982 and subsequently observed about 97% of the sky. [3] The facility is also known as IRAS 17150-3224. The nebula is an example of a protoplanetary nebula of the DUPLEX type. [four]

The nebula is difficult to observe because it has an angular size of only 16 '' and is dimly lit. IRAS 17150-3224 and its nebula are located in such a way that light from a star is blocked by the nebula, so that you can explore the ring-shaped structures surrounding the nebula. [3] The spherical structures around the nebula are created at the stage of the red giant , the final stage of star evolution. [3]
