Cotton Candy Nebula

Nebula in the constellation of Scorpius

The Cotton Candy Nebula is an astronomical object in the constellation of Scorpius. It is considered to fall into an unusual category of nebulae known as protoplanetary nebulae or post-AGB stars. A proto-planetary nebulae is an astronomical object that is in a stellar evolution phase where the star begins to discard its outer layers and is about to proceed to becoming a true planetary nebula, which is another astronomical object made up mostly of gaseous materials that was originally discovered by the IRAS satellite. IRAS was launched in January 1982 and overlooked about 97 percent of the sky. It is also known as IRAS 17150-3224. It is a good example of a DUPLEX-type protoplanetary nebula.
