The shape of the nebula is due to the central star expelling its layers as its core nuclear fuel supply diminishes. M27 resides 1,200 light years away. Portrayed in this image is the different atoms the make up the nebula complex. The green and blue consists of ionised oxygen (OIII) and the red, Hydrogen Alpha (Ha).
