The Water Lily Nebula, in the southern constellationofAra, is a pre-planetary nebula also known as IRAS 16594-4656, in the process of developing to a planetary nebula. It was discovered by Bruce Hrivnak and Sun Kwok in 1999.[3] The Water Lily is one of the pre-planetary nebulae containing polycyclic aromatic hydrocarbons, organic hydrocarbons otherwise constituting the basis for life.
