M27

M 27 is a planetary nebula, and is also known as the Dumbbell Nebula. It resides more than 1200 light years away from Earth in the constellation of Vulpecula and is about 3 light years in diameter. M27 hosts many knots of gas and dust, some of which are elongated and seen trailing away from the central star. Their sizes typically range from 17 billion to 56 billion kilometers, which is several times larger than the distance from the sun to Pluto. Also seen here is the faint outer shell of the nebula which makes its presence known when photographed using hydrogen alpha and oxygen III narrowband filters. These filters are designed to pass the spectrum of light associated with ionized hydrogen and ionized oxygen gasses.
