One Fine Ring Image courtesy ESOThe Fine Ring nebula, seen in a picture released August 1 by the European Southern Observatory, is an unusual example of a planetary nebula. Such space objects form after a sunlike star dies, expanding into a red giant and then shedding its outer gas layers, leaving behind a stellar corpse known as a white dwarf that’s surrounded by a shell of debris.
