The Apple Core Nebula

Messier 27 (M27) as known as the Apple Core Nebula, is a planetary nebula in Vulpecula. M27 is approximately 1,360 light years away. Discovered by Charles Messier in 1764 who added it to his now famous catalog used by amateur astronomers around the world. A planetary nebula has nothing to do with planets but is created when a star blows off its outer layers after it has run out of fuel to burn. Our own sun will suffer this fate without some external intervention in some 5 billion years.
