M27, Messier 27, Dumbell Nebula (363 words)
Messier 27 is considered by many to be the finest planetary nebula in the sky. Messier 27 is estimated to be approximately 1.5 light years wide [easily encompassing our entire solar system]. The visible part of Messier 27 is an expanding shell of stellar material that is set aglow by the central star which has since become a very strong source of ultraviolet radiation.
