It may take some imagination for some to picture a rose when they see the picture, however since most nebula's are named for their shape, nothing fits this one more than a rose.
A nebula is one of the last stages of life most normally sized stars. After the star has collapsed it leaves behind the cloud like gasses.
Imagine how romantic it would be if you could actually buy that rose nebula and present it to your significant other in the sky. Currently there are way to buy stars, however not entire nebulae If the day does come however, whoever is the first to pick this one up is going to be one lucky person!
